Release 2.0 (Build 231212)

  • Added new internal diagnostic features.
  • Added support for M1 Ultra processors.
  • Added support for the MacBook Pro (14 inch, M3, 2023)
  • Added support for the MacBook Pro (14 inch, M3 Max 16 cores, 2023)
  • Added support for the MacBook Pro (16 inch, M3 Max, 2023)
  • Confirmed official support for the MacBook Pro (14 inch, M3 Pro, 2023)
  • Confirmed official support for the Mac Studio (M2 Ultra, 2023)

Release 1.91 (Build 231127)

Minor optimization for System Monitor 6.

Release 1.9 (Build 231115)

  • Added preliminary support for Macs with M3 processors. Configurations with more than 12 CPU cores may only be partially supported at the moment. Full support is planned to be provided later.
  • Modernized organization of language support files.

Release 1.8 (Build 230829)

This version adds a new feature to detect situations where the system is an overload status in which additional load created by acquiring process statistics should be avoided. The "top 5" process monitoring functions in System Monitor will now automatically pause for one or two minutes when such a situation arises.

Release 1.7 (Build 230821)

  • Added full support for Macs with M2 Ultra processors.
  • Added new statistics and debugging features.
  • Fixes a performance problem for Macs with more than 800 internal hardware sensors where collecting sensor data could have negative impact on the communication between System Monitor and System Monitor Plus.

Release 1.6 (Build 230615)

  • Added temperature sensor support for the new Mac Studio (2023) and the new MacBoook Air (15-inch, 2023).
  • Added support for power supply temperature sensors on specific Macintosh models with Apple Silicon.
  • Fixes an issue with CPU core sensor identification for 8-core M2 processors.
  • Fixes a minor issue with diagnostic support for Intel-based Macs.

Release 1.5 (Build 230227)

  • Better sort order for temperature sensors on specific Macintosh model series with Apple Silicon.
  • Fixes a problem where a wrong temperature sensor was selected to be the characteristic CPU sensor for display in the menu bar. This only affects specific M1 models from 2021.

Release 1.4 (Build 230207)

  • Added support for new Macintosh models with M2 Pro and M2 Max processors.
  • Added support for monitoring an external temperature diode next to the CPU available on specific Mac model series with Apple Silicon.

Release 1.3 (Build 220905)

  • Added preliminary temperature sensor support for the MacBook Pro (M2, 2022) and MacBook Air (M2, 2022).
  • Added new feature to provide sensor information for total internal electrical power.

Release 1.2 (Build 220321)

Added preliminary temperature sensor support for the Mac Studio (2022).

Release 1.1 (Build 211118)

Added temperature sensor support for the MacBook Pro 2021 (all models).

Release 1.0 (Build 210906)

First official version of System Monitor Plus.
