- By user request, a feature to suppress access to S.M.A.R.T. hard drive sensors has been added to the command-line version of the program.
- The output channel “Screen Display” will no longer try to keep its screen position if the user changes a multi-monitor configuration while the program is not running. This makes sure the Screen Display cannot become invisible when its target monitor has been removed.
- The default number of displayed digits behind the decimal point is now automatically set to zero in cases where it is known that the sensor hardware does not provide more significant digits.
- When exporting readings, it is now possible to also use history windows in overlay mode as sources to get combined tables of readings for different physical quantities.
- If the application loses the network connection to a remotely monitored computer, related warnings will now be suppressed automatically when a change of the network configuration on the monitoring computer itself is the main reason for the disconnect. This is useful when a mobile computer monitoring a network leaves the WiFi area, for example.
- When remote-monitoring multiple computers with repaired logic boards that have invalid or erased hardware serial numbers, the application will now better keep track of the individual identifications of the affected systems.
- If the application is set to automatically reconnect to a set of remotely monitored computers on startup, the reconnect will now be performed less aggressively, one by one. This avoids temporary network overload when monitoring a large number of computers.

- Added a feature to detect a common damage of Leopard installations where users have intentionally destroyed the system’s speech synthesizer to save storage space.
- The readings of non-working GPU-load sensors provided by some of Apple’s graphics drivers for Leopard are now correctly suppressed by the application. Instead of displaying a constant zero value, the sensor will be removed entirely.
- Support for monitoring the frequency of Intel processors based on 45 nm technology (“Penryn”) has been withdrawn. The sensor might not reflect the true performance mode under all operating conditions.
- The mechanism to detect ambiguities in machine production dates has been optimized. Computers built in 2008 are now always displayed with their correct dates of production.
Release 4.5 (Build 080312)
- Added support for new portable Mac systems with Intel T8000 processors.
- Added temperature sensor support for the standard PATA hard drive of the MacBook Air.
- Support for on-core temperature sensors of Intel processors based on 45 nm technology (“Penryn”) has been modified: As confirmed by Intel, the core sensors behave no longer linear enough for the display of absolute readings in low temperature ranges. For this reason, support for core temperature sensors in 45 nm technology has been removed in Temperature Monitor. Hardware Monitor will display them as logical sensors showing “Core Hot” status information.
- The application will now detect first generation Intel Core processors which are affected by a hardware problem that can cause the core temperature sensors to stop working after the system wakes from sleep mode.
- Enhanced support for CPU clock frequency monitoring, especially on systems with Xeon 5400 processors and MacBooks running Leopard or running without a battery unit.
- Added a workaround for a security problem in Mac OS X which affects systems containing a GPU of the ATI Radeon X1000 series. In those systems, the GPU driver can crash, causing the screen content to freeze. Hardware Monitor now tries to avoid situations that could increase the likelihood for this defect to become noticable. NOTE: It is our policy not to discuss security holes in third-party products before giving the vendor (Apple) six months time to fix this problem.
- Corrected a problem with the display of Intel processor model codes when the model code was greater than 15.
Release 4.4 (Build 080211)

- The markers for showing extreme values in history windows can now also be selected via keyboard while the history drawer is open.
- The panel for connecting to remotely monitored computers now uses better support for multi-homed systems.
- The application no longer locks its history features when it detects a corrupt file for storing long-term history values. In this case the damaged data will be ignored and be removed automatically.
- The application now correctly suppresses frequency readings of Intel processors when the battery is removed from portable computers and the system has switched to restricted frequency control (Hardware Monitor only).
- Corrected a problem where the application did not show the sensor name in the user’s preferred language for the exhaust fan rotation sensor of the MacBook May 2006 model (Hardware Monitor only).
Release 4.2 (Build 070619)
- Added support for the new MacBook Pro series introduced in June 2007.
- Added support for a variety of internal temperature sensors of new hard drive models. This affects old Macintosh computers not supporting the AHCI standard.
- Users can now create a new artificial sensor type which monitors the current number of running processes (Hardware Monitor only).
- Users can now create several new artificial sensor types to monitor the network interfaces present in the system. It is possible to monitor the current number of incoming and outgoing packets, the current number of incoming and outgoing bytes, the current number of incoming and outgoing network errors, the current number of network collisions, and the total cumulative number of incoming and outgoing bytes. Sensors can be defined for each interface (Hardware Monitor only, requires Mac OS X 10.4 or later).
- Alert panels now display the exact time when the alert situation was detected.
- Selected display preferences for the Dock icon can now be set directly via the context menu of the Dock icon.
- By user request, the Lite version has a new menu item to immediately refresh the display of readings independent of the regular update interval.
- By user request, the Lite version has now support for sensor alerts. The actions to display alert panels, to play the warning sound, and to run external applications are supported.
- The handling of repaired or refurbished Macintosh systems which don’t have a valid serial number has been enhanced.
- Modified preference values are now committed to stable storage immediately when the preferences window is closed. This can reduce the likelihood that changes are lost when the application is used to diagnose problems on a computer with defective hardware.
- The application now correctly suppresses the display of electrical sensors for NVIDIA 7600 GT MXM cards in the 24-inch iMac. In that special configuration, the power supply of the GPU cannot be monitored (Hardware Monitor only).
- A problem was corrected where artificial sensors for monitoring RAID status could only be defined for one subset of a RAID 10 configuration. It is now possible to monitor all 3 RAID subsets of a RAID 10 with three artificial sensors (Hardware Monitor only).
- Corrected a problem where the application could crash when an artificial power sensor was created but one of the dependent voltage or amperage sensors was removed (Hardware Monitor only).
- Corrected a problem where the preferences to control an external LCD box could not be deleted (Hardware Monitor only).
Release 4.11 (Build 070207)
This is a small maintenance update which only enhances minor issues in the user interface:
- The menu-bar display will now be highlighted when the menu is open.
- It is now possible to delete the full sensor preferences set of a remotely monitored computer by a single mouse click when that machine has been taken offline and is no longer connected to the local computer.
- Corrects a scaling issue affecting the display of history curves when a long term history display had been zoomed out and the window width resulted in a horizontal time sampling resolution between 1 and 2 minutes per pixel.
- The resize behavior of the remote connection window was optimized.
- Enhanced compatibility of the disk saver feature with Mac OS X Jaguar.
- The internal hard drive sensor of Maxtor MaXLine Pro 500 (7H500F0) drives is now also detected by PPC-based Macintosh systems.
Release 4.1 (Build 070104)
- Added support for a large number of voltage, current (amperage), power, and light sensors for Intel-based Macintosh systems.
- Added full support for the new Apple Xserve Quad Xeon.
- Added support for S.M.A.R.T. temperature sensors in SATA drives connected via an SAS bus.
- Removed support for the internal Intel CPU sensor monitoring the target value of the core voltage. This is now superseded by the voltage sensors monitoring the actual core voltage supply.
- Added new “disk saver” preference which allows users to stop monitoring of internal hard drive sensors when the system is idle. Idle drives can now enter sleep mode and be held in sleep mode, independently of S.M.A.R.T. monitor time interval settings.
- The user interface for drawers in the history windows has been consolidated. There is now a single drawer for colors and extreme values.
- The color preferences for the visualization of sensors can now also be set via the color drawers of history windows.
- Added feature to add small labels to history curves. The labels use the sensors’ short names configured in preferences.
- Added feature to automatically recover from situations where one sensor stopped responding and the application was about to be halted by the operating system. (These situations can typically occur in machines where hard drives need more than 12 seconds to wake up from sleep mode, or where third-party applications are blocking the ATA busses for extended periods of time.) When such a situation is detected, the application will automatically stop all its activities, allowing the operating system to resolve the problem. After a certain amount of time, the application will reactivate itself and resume operation.
- The rounding of readings from frequency sensors of x86 processors has been updated according to Intel’s recommendations.
- Access to sensors where the user preference “Don’t acquire readings” was switched on is now prevented completely at the hardware level.
- Corrected a problem where the installation of the driver for extended x86 sensor support could fail if the application had been put in a folder which had a name with non-ASCII characters.
- Corrected a problem where a memory sensor in portable Core 2 Duo systems was misidentified as being a memory riser-card sensor.
- Corrected a problem where the internal temperature sensor of Hitachi Deskstar 7K500 drives was no longer seen as functioning sensor.
- Corrected a problem in the preference panel where some settings in the user interface were not updated correctly when the configuration tables for history windows and alerts were only controlled by keyboard, not by mouse.
Release 4.0 (Build 061108)
- Added support for a large number of new temperature sensors of Intel-based Macintosh systems. This includes thermal diodes monitoring the processors externally, GPU sensors, drive bay sensors and FB-DIMM sensors of the Mac Pro, etc.
- Added new feature to combine multiple history windows, making it possible to put sensors with different quantities into direct relation with each other. The user can define overlays for any selection of graphs.
- Readings of sensors which have raised an alarm are now displayed with warning markers in the sensor window, the screen display, and the menu-bar.
- The display of sensor readings in some output channels has been optimized further. No additional space is added in front of the readings which consumes less screen real-estate and enhances the appearance in windows where left-aligned layouts were selected.
- Corrected a problem where the curves of history graphs could show a flicker effect under very special circumstances.
- Corrected a problem where the speeds of switched-off fans were displayed as “—” instead of “0 RPM” on some specific PowerBook models.
- Corrected a problem where S.M.A.R.T. status probes could not be created for drives if the support status of the drives’ internal temperature sensors could not be determined.
NOTE: Some specific sensor location labels for Intel-based systems are subject to change and may not be final. Compatibility Reports for the new Core 2-based Mac series created via the Help menu of Hardware Monitor are welcome. Intel Xserve models are not fully supported yet. Support will be added when these systems become available.
Release 3.95 (Build 061010)
- Due to recent efforts in reverse-engineering Apple’s System Management Controller, it is now possible to support all fan sensors of all Intel-based Macintosh systems. The sensors and their parameters for permissible limits are found automatically. Additional temperature sensors are expected to be supported in the near future.
- The application can now control additional types of external LCD displays. The USB modules of the series CFA–632 and CFA–634 from Crystalfontz America, Inc. are supported. Additional free device drivers from Future Technology Devices International Limited (FTDI) are needed to make the modules accessible by Mac OS X.
- The application now contains a “backlight saver” for external LCD modules. The timeout intervals can be set individually for each connected module.
Release 3.9 (Build 060918)
- Added support for the 4 new iMac series introduced in September 2006.
- Added support for temperature sensors in some old hard drives which are not fully compliant with today’s implementation of the S.M.A.R.T. industry standard.
- By user request, Hardware Monitor now additionally supports monitoring of the case security lock for all Xserve systems. The lock position is monitored by a logical status sensor, where 1 denotes the normal, locked position, and 0 the unlocked setting.
- Artificial sensors to monitor storage space on volumes can now also be created for network volumes, not only for local disk partitions (Hardware Monitor only).
- If rulers are enabled for history windows, the application will now always try to keep the position of the crosshairs, no matter how the window or the selected time interval are resized.
- By user request, the old feature to display history curves in a scaled down fashion has been reinstated. Clicking on a new zoom button now allows to switch between a scaled down time axis, and display in full time resolution.
- Output of readings has been optimized to avoid leading blanks whenever possible. This produces better output, especially in the Dock and menu-bar channels, and in cases where the user has selected a combined Celsius/Fahrenheit display.
- The panel to display processor details will now better differentiate between logical processors, number of cores per processing unit, and physical number of processing units. It will also correctly reflect the number of currently deactivated processors.
- Corrected a problem where the marketing name of Xeon 5100 processors was not displayed in the processor detail panel.
- Corrected a problem where the application could raise a low sensor reading alert when the sensor was temporarily in a disconnected status.
Release 3.8 (Build 060825)
- Added support for the Apple Mac Pro.
- Added support for Growl notifications when defining sensor alerts. This makes it easier to receive alert messages by e-mail independently of the operating system version. (For more information see www.growl.info.)
- Users of large screens can now activate up to 8 sensor displays in the menu-bar.
- By user request, sensor readings in the menu-bar can now be configured to use the definable sensor display colors.
- The format preferences for sensor readings now allow to define up to 4 instead of 2 digits behind the decimal point. This change is necessary to allow the exact display of core voltages for Intel processors (Hardware Monitor).
- By request of many users, history windows are now resizable. The time axis is no longer scaled down, so users can scroll over the entire history data set in full resolution.
- By user request, the application will now track for each individual history window if it was open when quitting the application. Upon next startup, the application will restore the exact state of the history windows and no longer open all histories if only one was open. For roaming network users who use the application on different computers, different history window groups for different computer types will be respected individually.
- The application can now detect if a processing core of an Intel processor was shut down by the user, so the digital thermal sensors of that core no longer update their values. The sensor display of the affected core will switch to the usual “disconnected sensor” reading after some time.
- The application can now detect if it is being launched on Intel-based systems before the operating system is fully started. On very fast systems which were configured for automatic login and which launched the application as a login item, this could cause the program to run before the Intel support driver was started by Mac OS X. To avoid this problem, the application will now automatically wait 10 seconds for the CPU driver to become active.
- Corrected a problem where the display of precision and accuracy of temperature sensors could be switched to Fahrenheit (which is inappropriate) in the sensor detail panel.
- Corrected a problem of an early build of 3.7 where the application could crash when being used on an “Intel® Xeon® 5100 Sequence” processor.
- Corrected a problem of an early build of 3.7 which did not automatically open the history windows on startup if they were open during last shutdown.
Release 3.7 (Build 060618)
- Due to quality problems and intellectual property issues, support for the third-party software “SpeedIt” has been removed. The application now comes with its dedicated own driver to access internal information of x86 processors. The driver can easily be installed or uninstalled from within the application. The program will automatically notify the user if installation of the driver is recommended.
- The following additional sensors will be accessible on current x86-based Macintosh systems when the driver is active: the internal digital thermal sensors for each CPU core of Intel processors, current core voltage value of Intel processors (Hardware Monitor only), current true clock frequency of Intel processors (Hardware Monitor only).
- In addition, the System Information window of the application will be capable of displaying family, model and stepping numbers, as well as the internal identification of x86 processors after the aforementioned driver has been installed.
- Added new preference values to adjust the ratio of the font sizes for display of the sensor labels in relation to display of the sensor readings. The preference settings are available for the sensor window and the screen display output channels.
- The policy for detecting temperature sensors that are built into hard drives has changed: If the application detects a SATA drive under control of an Intel-based Macintosh system using AHCI, it will automatically assume that this drive contains a working temperature sensor compliant with the latest version of the ATA and S.M.A.R.T. standards. Up-to-date hard drives will no longer need explicit support by the application but will be accepted automatically. The column for temperature sensor support in the Drive Overview window has been removed.
- The reference manual now gives an example on how to define a sensor alert trigger to automatically shutdown the system when readings exceed adjustable threshold values.
Release 3.6 (Build 060504)
By request of many interested customers, this update is published earlier than initially intended. You only need to update from 3.5 if you like to use one of the following modifications:
- Due to very high demand, this version adds support for the third-party software “SpeedIt” by InCrew Software, Spain. SpeedIt is a kernel extension for Mac OS X which grants user applications permission to access the on-chip CPU temperature sensor of Intel-based Macintosh systems. The monitoring application will automatically detect if SpeedIt is running on the system. If yes, the features of SpeedIt will be used to acquire readings from the CPU. For additional information, please see the FAQ chapter of the reference manual.
- Enhanced support for the first generation iBook G4, where temperature sensors of the type Analog Devices ADT7460 did not deliver their readouts fast enough with specific Mac OS X versions, causing intermittent display of zero values.
- Corrected a problem where temperature sensors controlled by the G4 version of the Apple System Management Unit were displayed as being disconnected.
Release 3.5 (Build 060428)
The following items have been added to Hardware Monitor. They are not available in Temperature Monitor:
- Added new feature to create artificial software sensors which monitor aspects of the operating system. This includes the load on each processor core, disk usage, free storage space and used storage space for each volume, free memory, used active memory, used inactive memory, used non-pageable memory, current number of page-ins and page-outs, allocated swap space, S.M.A.R.T. drive verification status for each drive supporting the S.M.A.R.T. standard, RAID operation status for each software RAID set created by Mac OS X, electrical power for user-definable pairs of voltage and amperage sensors, remaining battery capacity for each battery unit.
- Added new feature to control external alphanumeric LC display modules, connected via USB by a Code Mercenaries IO-Warrior USB controller chip. Output on the LCD is fully user-configurable. Next to sensor output and text elements, an external display box can be configured to show current date, time, computer name, kernel version number, OS version number, OS build number, IPv4 addresses of all physical network interfaces, and bar-graphs for sensors representing percentage values.
- Added a new user preference to allow the sign of battery current sensors to change, reflecting whether the respective battery is charging or discharging.
- Added support for ACPI-compliant battery units of non-Apple computers.
- History records for non-temperature sensors are now automatically added in the same user session if Hardware Monitor is switched from demo to unlocked mode. It is no longer necessary to restart the application to get history data of the previously locked sensors.
The following items apply to all variants of the software:
- Added support for several new S.M.A.R.T. hard drive sensors.
- The format of labels for the y-axis of history graphs has been enhanced.
- The policy for the display of alert messages has changed: The application no longer locks its user interface until the user has acknowledged an alert. If multiple alert messages arrive before the user has acknowledged a message, new alerts will overwrite previous ones.
- The panel for computers which don’t contain sensors has been enhanced.
Release 3.4 (Build 060302)
Added support for new Macintosh systems which use the “smart battery” industry standard. Production dates and serial numbers of “smart” battery units can be displayed in a new battery detail panel.
Note to users of Temperature Monitor: If you are already using version 3.3 of Temperature Monitor, you only need to update to 3.4 if you want to remotely monitor the battery of a MacBook Pro running a licensed copy of Hardware Monitor Remote 3.4. In all other aspects, version 3.4 is identical to 3.3.
Release 3.3 (Build 060216)
- Added a new system information detail window for Intel-based Macintosh systems. The window displays system management data like component serial numbers, hardware details, and vendor information for the following categories: Computer system, processors, cache units, memory devices, firmware, system mainboard, system enclosure, internal and external connectors, expansion slots, onboard devices, and jumpers.
- Added extended support for nVidia graphics cards containing more than one equally named temperature sensor. The application now better keeps track which sensor is which.
- Added support for hard drive sensors accessed by SATA controllers that follow the AHCI standard, which is a new feature of Mac OS X 10.4.4.
- Added support for several new S.M.A.R.T. hard drive sensors.
- Added preliminary support for the iMac Intel Core Duo.
- Added new feature to automatically correct raw firmware sensor labels if sensor preferences had been set with an old version of the application which did not officially support a specific sensor yet.
- The FAQ chapter in the reference manual has been revised.
- Corrected a problem where the load sensor of the ATI Mobility Radeon 9700 was erroneously detected as temperature sensor.
- Corrected a problem where roaming network users which access more than one computer could not correctly import preference sets from a computer of the same model type.
Release 3.2 (Build 051125)
- Added support for the third-generation iMac G5 (iSight). If you used a release prior to 3.2 on the new iMac G5, it is recommended to delete your preferences file to get updated sensor labels.
- Added support for several new S.M.A.R.T. hard disk sensors.
- Added new option to let history windows show absolute instead of relative time designations.
- The extreme value tables in the drawers of history windows will now remember their size settings, and the drawers will now open with more appropriate initial widths.
- The wait panel of the menu-bar version (Lite application) was replaced by a message in the menu-bar.
- The display of detail information for some production sites and the Dallas 1631 sensor chip have been optimized.
- The reference manual has been revised.
Release 3.1 (Build 051110)
- The new version contains a workaround for the problem that Mac OS X did not update the readings for some specific low-priority sensors of certain Macintosh models. Now all sensor values are refreshed under all conditions. This affects temperature sensors of the 15-inch and 17-inch PowerBook G4 models released in 2005, as well as the ambient air temperature sensors of PowerMac G5 models.
- Added support for the new PowerMac G5 Dual Core systems.
- Added support for the new PowerBook G4 (Super Drive Dual Layer) systems.
- Added support for ambient light sensors found in the latest PowerBook models (Hardware Monitor only).
- Added support for several new S.M.A.R.T. hard disk sensors.
- The display of the extreme value table in the drawer of the history window has been optimized.
- Corrected a problem where keyboard navigation in the sensor preference outline view did not update the entry fields.
- Corrected a problem where curves in the history graphs were displayed with the wrong time scale for certain intervals.
- Corrected a problem where the clock frequencies of the local computer were displayed in the system info window although a remote computer was selected.
Release 3.01 (Build 050908)
3.01 is a maintenance update which only affects a small minority of users. If you are using release 3.0 with a Mac OS X system not among the problematic cases outlined below, it is neither necessary nor beneficial to download version 3.01.
- Added support for Mac OS X installations with incomplete or unusual configurations. In particular, this affects the following situations: Mac OS X systems where the computer name has been deleted, Macintosh computers with repaired or replaced mainboards where the hardware personalization fields in Open Firmware were empty, system installations that are very slow in waking up from sleep mode.
- Corrected a problem wheren the Connect button in the remote connection panel might have stayed in disabled mode when you manually entered data to connect to a remote computer in a different subnet.
Release 3.0 (Build 050826)
- The application can now monitor remote computers via a TCP network connection. The user can connect to an unlimited number of remote computers using Bonjour technology. The add-on Hardware Monitor Remote and an additional registration key for each computer monitored simultaneously is required to use this feature. It is not necessary that a user has logged in at the remote computer.
- The application has now a multi-threaded architecture and its core was rewritten completely.
- The history curves are no longer interrupted when the application waits for a user response in a dialog window.
- The version numbers of Hardware Monitor and Temperature Monitor have been synchronized to avoid confusion. (This means Hardware Monitor has been updated from release 1.5 to 3.0, skipping version 2.)
- Added new feature to display S.M.A.R.T.-compatibility and S.M.A.R.T. verification status of all disk drives.
- Added new feature to display the admissible limits for all sensor locations for which Apple’s specifications are known. The limits are displayed in additional columns in the Sensor Overview window.
- Added new feature to locate and visualize extreme values in the history windows.
- Added support for S.M.A.R.T. temperature sensors of several new hard disk models.
- Added preliminary support for Intel-based Macintosh systems.
- Added support to differentiate between multi-processor and multi-core/multi-thread systems.
- Added a user preference to keep the position of the screen display fixed, so users can no longer shift the display by mistake.
- Added user preferences to set customized speech output names for each sensor.
- Added feature to let the program open an application or document when a sensor alarm is triggered.
- Added feature to change the alignment for the display of readouts in the sensor window and screen display.
- Added user preference to change the background color of each history graph.
- Added feature to restore the time intervals selected in each of the history windows when the application is relaunched.
- Sensor types are now visualized using additional icons.
- The System Information window has been simplified.
- Hardware Monitor has got a redesigned icon.
- The preference window has been redesigned completely.
- Panther systems affected by security problem CVE-ID: CAN–2005–0985 are now handled automatically, so user intervention is no longer necessary. Defective Mac OS X fan drivers are no longer accessed.
- The application now contains a workaround for a bug in nVidia graphics card drivers: If the drivers of GeForce 6800 cards mistakenly report that the cards’ sensor identifications have changed, the application will no longer generate new preference settings for the “new” sensors of the supposedly “replaced” card.
- Corrected a problem where pulse-width controlled fans of GeForce 6800 cards have been mistakenly reported as fans with RPM sensors.
- Corrected a problem with the labels of history rulers where minutes and seconds could be confused when a time interval of less than 1 hour was monitored with the ruler crosshair.
- Corrected a problem where not all non-refreshing sensors were detected on some specific PowerMac G5 models without liquid cooling system.
- Corrected a problem where a short-term history window was not updated when the sensor update interval was increased in the same user session.
- Corrected a problem where the Dock tile was not restored to show the application icon when the user launched the application via a permanent Dock entry and had defined a very short update interval.
- Corrected several hyper-links in the English version of the reference manual.
- Several new sections have been added to the reference manual.
Release 2.5 (Build 050228)
- Added support for the 12-inch, 15-inch, and 17-inch PowerBook G4 models released in February 2005. Note that current versions of Mac OS X are not capable of refreshing most temperature sensor readings of the February 2005 15-inch model, and the February 2005 17-inch model.
- Support for temperature sensors of several hard disk models has been added.
- Added new feature to display disk monitoring detail data for Apple Xserve drive modules.
- Added new feature to display the number of charge/discharge cycles as well as the maximum capacity of battery units of portable computers (Hardware Monitor only). This feature is only available on Mac OS X versions which are capable of supporting this.
- History data and current sensor readings can now also be exported in CSV format in addition to text files.
- Because different versions of Mac OS X handle the sign of the battery amperage values differently (indicating that the battery is charging or discharging), Hardware Monitor will now display positive values only to avoid confusion.
- By user request it is now possible to launch the Lite version from the preferences panel of the full version. This allows a simple switch between the Lite and full version when the user wants to change preference settings for the menu-bar display.
- Fixed a problem where the option to display readings in Celsius and Fahrenheit simultaneously could cause an incorrect display of temperature extreme values in the minimum/maximum window.
Release 2.4 (Build 050128)
- Support for many new hard disk models has been added.
- Support for some previously undetected sensors of the Xserve and the Xserve G5 has been added.
- A workaround for a bug in Mac OS X 10.3.7 has been added: On computers with incorrect DNS configurations, Panther 10.3.7 imposes a delay of approximately 1 minute to applications which have to know the computer’s TCP/IP name. Among many other programs, Temperature Monitor and Hardware Monitor were affected by these delays. The applications will now detect this problem and cancel the request after 3 seconds. This allows the programs to be used in incorrectly configured TCP/IP networks with Mac OS X 10.3.7.
- Alarm triggers for temperature sensors now automatically recompute their thresholds when the user switches to a different temperature unit.
- The boot ROM version is now additionally displayed in the system overview.
- The application notifies users who have forgotten to define different colors for curves in the history graphs.
- Fixes a problem where old readouts could be displayed in the Dock when the application was quit.
- Many small changes and optimizations in the user interface.
Release 2.3 (Build 041123)
- Support for all sensors of the iMac G5 has been added.
- Support for sensors of nVidia GeForce 6800 graphics cards has been added.
- Preliminary support for the sensors of the Power Mac G5 October 2004 model has been added. Compatibility reports for this model sent with the respective option in Hardware Monitor are welcome.
- Support for a large number of additional hard disk temperature sensors has been added.
- The floating window has been renamed to screen display window. It can now either float on top of all windows (as the previous version), or support a new setting “backdrop window”, which attaches it to the background image of the Desktop.
- A new status window was added which can display minimum and maximum readouts of all sensors for a selectable time frame of up to one week.
- An option was added to automatically save history data not only when quitting the application but also in a regular, selectable time interval. This allows you to save reference data for cases where your computer is affected by emergency shutdowns due to overtemp conditions.
- By customer request, the readouts in the sensor window and the screen display window have been made user-selectable. So the current values can be easily copied to other applications without having to use the export feature.
- A new feature was added to move the screen display window back to the middle of the screen after you have made layout changes or modified your multi-monitor configuration to the effect that the window was placed outside the visible screen area.
- Long sensor names in the sensor window or the screen display window are no longer cut off if they are very large. The windows automatically adjust to the best layout possible. For this reason, window locations and sizes may change when you upgrade from a previous release to version 2.3.
- The preference panel now shows a warning if the access interval for hard disk sensors is in contradiction with Mac OS X energy saver preferences you have set for hard disks.
- The preference panel allows you to reset the fonts for sensor and screen display windows to their default settings.
- The application no longer deletes preference settings of sensors that have been removed from the system or are temporarily offline. This also includes cases where hard disk temperature sensors have been categorized as being unreliable. Sensors which have been removed finally can be deleted manually from preferences.
- The filter method that rejects values of unreliable hard disk sensors has been optimized.
- The application now automatically detects if the sensor of an offline hard disk is reconnected to the system.
- A new menu item which allows an enforced re-scan of the current connectivity of sensors has been added.
- Several menu items which open or close status windows have been moved from the Monitor menu to the Windows menu to match the user interface of future versions of Mac OS X.
- By customer request, the command line version of the application contains new options which can be used to generate reports in CSV format.
- The panel for demonstration mode has been redesigned completely.
- Fixed a problem where the import of sensor preferences for roaming users working on several similar hardware models in a Mac OS X network did not work reliably.
Release 2.21 (Build 040924)
This is a maintenance update only affecting minor issues.
- Corrected a problem where the sensor window was not resized correctly after it was moved off the main screen in a multi-monitor setup, or the layout was changed for a position near the screen border.
- Corrected a problem where the color wells in the preference window could not be clicked under certain circumstances.
- Corrected a problem where alerts were triggered for the wrong threshold value.
- The user interface for the warning of an unstable operating system version was changed (Hardware Monitor only). It is now possible to set a user preference that disables the warning per computer. The preference panel contains a new button to re-activate all disabled sensors.
Release 2.2 (Build 040908)
- Translated descriptions for some sensors of the PowerBook G4 (12 inch, 1.33 GHz) and the cooling pumps of the Power Macintosh G5 (dual 2.5 GHz) have been added.
- Support for temperature sensors of some hard disks of the Western Digital Raptor series has been added.
- If the menu-bar display is switched off, the Lite version of the application will now display a small icon in the menu-bar only. This reduces consumption of screen real estate for the Lite version to the smallest amount possible.
- The font for the menu-bar display can now be configured by the user.
- The acquisition of data can now be disabled by the user for each sensor individually.
- Readings of hard disks which send invalid data after waking from sleep mode are now filtered out if they are implausible.
- When the feature to announce monitored sensor readings on value changes has been activated, an additional tolerance value can be configured now to control speech output.
- The application detects operating system versions which are eqipped with defective fan control drivers. If access to fan control bears the potential danger a Kernel Panic is triggered due to these defects, the application will display a warning and will offer to disable access to affected sensors.
- Corrected a problem where standard sensor window and floating window could move a few pixels in vertical direction after the application has been relaunched.
- Corrected a problem where values were added to the short-term history diagrams in an incorrect time frame if certain values in the preference panel were changed.
- An incorrect multiplier for the display of pulse-width controlled fans on Power Macintosh G5 systems has been corrected.
- Several minor changes in the user interface.
Release 2.1 (Build 040804)
- Support for new voltage and fan sensors has been added.
- Support for temperature sensors on the hard disk models Seagate ST340015A, Fujitsu MHT2080AT and Western Digital WD800JB–00FMA0 was added.
- Font types and font sizes for the sensor window and the floating window can now be set by the user.
- Horizontal and vertical layout of the sensor window can now be set independently of the floating window.
- A new function was added which tests for systems with variable clock frequencies.
- The System Info window now differentiates between nominal and actual clock frequencies at startup time.
- A new menu item was added to the Lite version which allows to launch the “big” version.
- If multiple monitors are connected in a vertical setup, the floating window can now be dragged to the screen “above” the menu bar.
- The FAQ section in the documentation has been extended.
- A problem was corrected which could prevent the hwmonitor command line program from being unlocked.
- The command line program tempmonitor which was missing in some distribution packages was added.
- A problem affecting the incorrect display of production data for some particular models manufactured for the US markets has been corrected.
- An incorrect multiplier for the amperage display of batteries has been corrected.
Release 2.0 (Build 040719)
- The program now supports an unlimited number of sensors per computer. It tries to support all Macintosh systems equipped with sensors that are accessible by Mac OS X without needing third-party device drivers.
- Support for on-die temperature measurement of G5 processors has been added. This the first Mac OS X application with this capability that is distributed publicly.
- Support for temperature measurement of hard disks has been added. With this feature the application will now also support older Macintosh models that neither have temperature sensors on their mainboards, nor are capable of processor-based temperature estimates. (This feature is only supported with Mac OS X 10.3 or later. For technical reasons it cannot be offered for Jaguar.)
- The temperature sensors of a variety of iBook and PowerBook computers as well as sensors in some graphics cards are additionally supported.
- The program is no longer terminated when no sensor has been found. In this case it is still possible to read the documentation or use the system information feature.
- Rendering issues in connection with shadows not updated correctly for the floating window have been resolved.
- The application now makes sure speech output uses exactly the same update interval as graphical output, so there are no longer discrepancies between spoken and displayed values.
- By user request, a feature was added to optionally display temperature values in degrees Celsius and degrees Fahrenheit simultaneously.
- By user request, a feature was added to optionally zoom the visualization of history data into the current value range, so the curves are presented without losing details.
- By user request, the display size of readings in the Dock has been enlarged.
- By user request, readings in the Dock can optionally by displayed as plain text lines, enlarging the display even more.
- By user request, the application can be launched in a “Lite” version which only displays readings in the menu bar but doesn’t use any space in the Dock.
- By user request, the number of digits after the decimal point is held constant when displaying readings. The format can now be specified for each sensor.
- By user request, a feature was added to monitor if values exceed or fall below definable limits and announce this by alarm messages. Optical, acoustical and spoken alerts are possible.
- The history graphs now contain an additional feature to display rulers that allow to exactly determine history values and their time.
- Long-term history data is now saved persistently when the application is quit. One week of readings per sensor, per computer is stored.
- The application supports “roaming” users in networks who use different computers with central private folders on a file server. In this case, the application stores individual sensor preferences per computer, allowing the user to take over configurations of similar machines. History data is stored per sensor, per computer, per user.
- The history graphs no longer show unavailable readings by horizontal lines. Time intervals that have not been recorded will appear as interruptions in the curve.
- The user can define an unlimited number of history windows and map sensors to them. An unlimited number of curves for the same type of physical quantity can be super-imposed in one graph.
- A feature to display processor type, frequencies, production date and production place, memory and cache sizes, as well as operating system version has been added.
- A feature to display the MPU product data of G5 processor cards has been added.
- A new window to display an overview of all sensors has been added. The window allows that technical detail information about each sensor hardware can be queried.
- Sensors can be identified by customized colors and names. For each of the different output channels, a different sensor list can be configured. Windows can display sensor readings in vertical or horizontal layout. A color legend can be displayed in a drawer of each history window.
- Windows can now be printed.
- Current readings or history data can be exported to text files.
- A feature was added allowing the software to check for newly available updates on the Internet.
- The BSD command line version of the program was revised and now supports an unlimited number of sensors as well.
- The menu was restructured.
- The documentation was rewritten completely.
- The program is now also distributed in a “pro” version under the name Hardware Monitor. The pro-version additionally displays battery data of portable computers, as well as fan, voltage, current, capacity and power sensors on supported computers. The pro-version is distributed as shareware. Temperature Monitor remains available for free.
Release 1.4 (Build 031103)
Support for temperature sensors of the next generation aluminum PowerBooks (Apple PowerBook G4 15-inch FW800) and support for the PowerMac G5 have been added. Please note that the temperature reading displayed for G5 models is not the CPU core temperature. See the Release Notes for further information.
Release 1.31 (Build 030721)
This is a maintenance update which fixes minor bugs in the user interface. No feature has been modified or added.
- Corrected a problem that could cause temperature degree symbols not to be displayed correctly if the program was launched by a user with non-Latin scripting systems. This affects system installations where Chinese, Japanese, or Korean is pre-selected as primary language.
- Corrected a problem where temperature display was delayed after program launch, depending on the update interval preferred by the user.
Release 1.3 (Build 030716)
Support for temperature sensors of aluminum PowerBooks (Apple PowerBook G4 12-inch and 17-inch) has been added. Thanks to Kevin Francis Besig for beta-testing the new release.
Wording in the menu bar of the English user interface was changed.
Release 1.2 (Build 030621)
- The shadow of the floating window can be switched off to improve readability.
- Documentation has been updated.
- The hardware survey was completed. Application development will now be frozen until Apple ships new hardware that makes changes necessary.
Release 1.1 (Build 030620)
- Because a few users are under the mistaken belief it is a software problem when their hardware is not supported, the support status panel has been completely redesigned. The program now returns very detailed information why it is technically impossible to run the software on some systems.
- The application now supports an additional display of the temperature in the menu bar.
- It is no longer necessary to press the return key when entering a new update interval in the preferences panel.
- A problem with the Apple Help Viewer not automatically displaying the title page of the online documentation when launched with a non-English primary language has been corrected.
- The FAQ page has been extended.
- The hardware compatibility list has been updated.
- Typos in the online documentation have been corrected.
Release 1.0 (Build 030618)
First official version of Temperature Monitor.
