System Monitor Add-On
This application is an add-on for System Monitor, designed for Macs with Apple Silicon processors. System administrators can use it to install or remove an additional software library that allows System Monitor to get access to more temperature sensors. The library must be published separately, because Apple doesn't permit unrestricted access to Apple Silicon sensors within Apps from the Mac App Store.
The program uses a simple two-button approach to either add or remove the software package, which behaves like a plug-in. When you installed the plug-in and activated it in your preference settings of System Monitor, supported temperature sensors will be added as a dedicated section in the main sensors menu of System Monitor.
Most aspects of Apple hardware are not documented. Details about hardware sensors are considered a trade secret of Apple, and there is no official way to get readings and their exact meaning. For this reason, the temperature sensor equipment shown by System Monitor might strongly vary between different model series. The shown list of sensors is usually not complete, but has been pre-selected to present a characteristic temperature behavior of each computer model. Recently released models may not be fully supported yet.
System Monitor Add-On is electronically distributed software. You can download the product free of charge.
