Limitations due to AppStore sandboxing and other Known Issues:
An AppStore App is not allowed to read system sensors (SMC), so we cannot show detailed temperatures and other sensor data such as fan speed.
An AppStore App is not allowed to read all processes on the system. This means that the Top-3 App List will not necessarily contain the processes that are currently using the most resources. The List will, however, show the applications that are using the most resources.
MONIT will underreport Memory usage for Applications in the Top-3 List that spins of sub-processes which we are not allowed to read. In practice, MONIT is quite accurate given the sandbox restrictions it operates under, but for certain applications, it will underreport. If you compare with Activity Monitor, you should compare with “Real Memory” and aggregate memory usage of sub-processes.
The thermometer uses an Apple API that does not seem to work properly on older Macs. On MacBooks from 2015 and later it appears to work fine.
- This is a bigger update which brings sensors information to the widget and exact process resource usage. A small Monit Helper program is needed for the cool stuff in this release. The Helper program is free and can be downloaded from our Web-Pages. Here is a summary of changes in this version.
New: Show CPU and GPU Temperature
New: Show and animate Fan speed. The fan icon correlates rotation with the physical fan rpm
New: Report CPU and Memory usage for the top 5 Processes that use most resources. [*]
New: Show Processes using Disk i/o. [*]
New: Show Time on Battery since Boot for MacBooks.
Fixed: Support for both macOS High Sierra 10.13 and Mojave 10.14
Fixed: UI and DarkMode improvements
* With the Helper, the ‘top five lists’ of processes using CPU, Memory, and Disk i/o is exact and include all processes running on the system. Values are aggregated into the parent process so it is possible to, for instance, see how much Memory Safari is using by including all its sub-processes.
macOS 10.12 or later, 64-bit processor
