TinkerTool System 4 Version History

Version 4.97 (Build 180411)

  • Added new user interface to the product activation and evaluation features in order to be compliant with the General Data Protection Regulation of the European Union (EU Regulation 2016/679).
  • Fixed a problem where the processing of group memberships of a user could fail if the user was in more than 16 groups.
  • Fixed a problem where notification center messages for available software updates and Time Machine issues could crowd each other out.

Version 4.96 (Build 170929)

This version clarifies the (unsupported) state of removing privacy-related files from Safari 11 and adds the associated documentation.

Version 4.95 (Build 170829)

  • Performance of the Diagnostic pane has been optimized to better support configurations with a network-based Time Machine backup device.
  • Added an assistance mode for product registration.

Version 4.94 (Build 170712)

  • Added a user notification to indicate temporary performance problems when TinkerTool System is communicating with a slow Time Machine device.
  • Fixed a problem where the feature for the enforced emptying of the Trash might not have shown the system volume as possible candidate under specific circumstances.
  • Several small optimizations.

Version 4.93 (Build 170125)

This is a maintenance update, enhancing performance in situations after Time Machine diagnostic features have been used on systems with slow Time Machine destination devices.

Version 4.92 (Build 161212)

The user interface for Time Machine diagnostics was simplified. It now works more reliably with network-based backup sets or when using multiple destination disks.

Version 4.91 (Build 161017)

  • The handling of custom permissions, access control lists and extended attributes when deactivating and restoring caches was enhanced.
  • Added a workaround for a design issue of OS X El Capitan, relevant when users are switching back and forth between enabling and disabling System Integrity Protection while using the smart cache deactivation features of the application.
  • To guarantee perfect cache restoration under all circumstances, smart deactivation for the user’s personal high-speed caches is no longer offered when using OS X El Capitan.
  • On OS X El Capitan, conventional cache cleaning is added as last-resort alternative for the user’s personal high-speed caches and the core operating system caches, which is otherwise prevented or limited by System Integrity Protection.

Version 4.9 (Build 160912)

  • The features to remove hidden Macintosh support files, to clean Macintosh support files from removable disks, to create links, to protect files, and to change Macintosh file attributes have been modified to no longer require privileged operations if they are executed on disks which are set to ignore file ownership.

  • Added new feature for OS X El Capitan to change the computer setting for optimizing system performance for server operations with OS X Server.
  • Analyzing log files is now automatically decoupled from application startup if a high number of logs is detected. Excessive log files on a computer no longer slow down the launch of the program.
  • The use of different workarounds for bugs in OS X Yosemite and OS X El Capitan could create subtle compatibility problems with version 4.8 if operating system, main application, privileged auxiliary program, and the Standalone Utility have been updated in a specific order. Launching version 4.81 analyzes this situation and replaces the helper programs if necessary to resolve such problems.

Version 4.8 (Build 160823)

  • Added support for upcoming versions of Safari.
  • Added additional features and documentation to detect cases where System Integrity Protection is causing internal failures of OS X El Capitan.

  • Fixed a problem where specific files of synchronized iOS devices were shown with an incorrect date for the feature to clean outdated log files.
  • Fixed a problem where the evaluation of memory size could be wrong under specific circumstances.
  • Prepared application for upcoming operating systems.
  • Added support for TinkerTool 6 Preview edition.

Version 4.6 (Build 160518)

  • Added new registration features for licensing with immediate gratification and volume licensing.
  • Added new feature to detect a common corruption of the System Integrity Protection of OS X El Capitan which is the reason for a series of system malfunctions.

  • The behavior of the security component was optimized for cases where the operating system was temporarily overloaded exceeding the maximum number of open files.
  • Fixed a problem with specific versions of OS X where display of the modification time of the Xprotect anti-malware database stopped updating.
  • Fixed a problem with the user interface of the Special Permissions tab item of the ACL pane where the Apply button could have the same function as the Revert button.

Version 4.51 (Build 160229)

This is a maintenance update which doesn’t change core functionality.

  • Web communication during software update and evaluation checks is now fully compliant with Apple’s new App Transport Security guidelines.
  • Fixed a problem where the security component of the application could stop responding due to an overload of the task dispatch management of OS X El Capitan. The application will now give OS X more time to clean up its internal communication channels before sending new requests.

Version 4.5 (Build 160120)

  • Added new feature to disable support for IPv6 on active network interfaces (OS X 10.10.4 or later).

  • Enhanced support for El Capitan users that run a customized configuration of System Integrity Protection.
  • Many small optimizations in the user interface.
  • Fixed a minor problem with the presentation of System Management information on some Macintosh model series where the program did not correctly differentiate between unavailable and unimplemented fields.

Version 4.31 (Build 150925)

  • The reference manual has been updated for OS X El Capitan.
  • Corrected a problem where the menu item to go back to the preceding control pane did not work as expected.

Version 4.3 (Build 150818)

  • Added new privacy feature to remove entries for Recent Searches in the search field of Safari.
  • Added new feature to remove adware applications of the category “Buca/Bundlore Ltd”.
  • Added new feature to enable the diagnostic startup option to enforce stricter separation between kernel memory and user memory. It can be used to protect the system against specific security attacks published in August 2015, at the expense of performance.
  • Added feature to change the permission filter for applications running on the graphical user interface. Apple has reintroduced this possibility in the latest versions of OS X Yosemite or later, after removing it for the second time in the history of the operating system. (OS X 10.10.4 or later is required.)
  • Added support for future versions of Safari.

Version 4.0 (Build 141016)

TinkerTool System 4 requires OS X 10.10 Yosemite or later. It is a paid upgrade for users who purchased a license for TinkerTool System Release 2 before July 1, 2013. TinkerTool System Release 2 remains available and can be used on the operating systems Mac OS X Snow Leopard (10.6), Mac OS X Lion (10.7), OS X Mountain Lion (10.8), and OS X Mavericks (10.9).

Version 4.0 (Build 141016) is a pilot release to give early adopters of OS X Yosemite the chance to use TinkerTool System already. Because Apple did not disclose all necessary documentation on Yosemite at this early time, this version only contains context help, but not the complete 180-page reference manual.

Version 4 focuses back on the operating system itself. All features related to third-party software or external applications have been removed. The only exception are functions for programs which had been part of OS X in the past, such as Adobe® Flash® Player or Xcode.

  • The application can now exhaust modern hardware to its limits, making full use of multi-core processors and flash/SSD storage. Depending on computer model, some features may run up to 20 times faster compared with previous versions of the software.
  • All used technologies have been modernized to comply with the latest guidelines for OS X Yosemite.
  • The user interface has a completely new layout, but maintains the known overall design.
  • The security architecture complies with Apple’s latest standards for system utilities and uses multi-tier privilege separation.
  • Support for full keyboard control has been enhanced. The application can be used without a pointing device.
  • Accessibility features have been redesigned, enhancing support for handicapped users.
  • The Info pane has been rewritten completely and uses a new user interface.
  • Added new feature to search for features by keyword.
  • Added new preference setting to disable any animations when switching between panes.
  • Added new feature to clear the DNS client cache as option during the cleaning of the directory services cache.
  • Added new feature to recreate the XPC helper cache.
  • Added new feature to diagnose Time Machine operation by comparing two selected backups.
  • Added new feature to show the system’s blacklist for automatically disabling App Nap in specific applications.
  • Added new feature to show the system’s blacklist for automatically disabling high-resolution (“Retina display”) functions in specific applications.
  • Added new feature to show the system’s blacklist for automatically preventing the launch of incompatible applications.
  • Added new feature to show the system’s blacklist for automatically deactivating incompatible drivers and other kernel extensions.
  • Added new feature to assess the security impact of applications, regarding App Store curation, Gatekeeper, and Application Sandbox settings of individual programs.
  • Added new feature to select if Access Control Entries should have implicit or explicit inheritance when propagating permissions in folder hierarchies.
  • Added new feature to permit the system to use unsigned kernel extensions
  • Added new startup setting to disable the compressed memory feature of the operating system
  • The settings to define the style of the login screen have been reinstated.
  • The feature to remove support for processor architectures from applications now additionally supports the pre-configured setting “keep 64 Bit Intel code only”.
  • The functions to run the periodic maintenance scripts and for code thinning in applications have been moved to a pane for legacy features.
  • The feature to remove unused preference files was removed, because the current manner in which such files are handled today no longer allow to safely determine the usage state of the files.
  • The pane System Issues has been removed temporarily, giving Apple a chance to resolve open problems in Yosemite. It will be reinstated in future free updates of TinkerTool System 4.
  • The option to ignore applications from Adobe® when removing language packages is now always enforced. Applications from Adobe® and Microsoft® won’t be touched.
  • The user interface to reset permission settings on the system volume has been removed, because features of the operating system should not be duplicated in the application.
  • The user interface to control visibility of the user’s Library folder has been removed, because it has been superseded by the Finder.
  • The user interface to define custom MTU setting has been removed, because it has been superseded by System Preferences.
  • The user interface for the following system settings has been removed, because OS X 10.10 is no longer supporting the related options: launch applications via the creator code of documents, disable Bonjour Sleep Proxy notifications, disable access to the “App” part of the App Store, permission filtering for new file system objects created by graphical applications.

TinkerTool System 4 begins a new product line. The section above lists changes in comparison to TinkerTool System Release 2 version 3.4. For more information about the version history of TinkerTool System Release 2, please see the respective application of Release 2.
