What is Hardware Monitor?

Hardware Monitor is part of an application suite for the macOS operating system. The applications are designed to read out the hardware sensors built into specific Macintosh models. Additional information can be retrieved as well. Among other data, this includes:

Hardware Monitor Usage Situation

We try to access sensors on as many Macintosh computer types as possible. However, a prediction which sensors are available in which models is not possible.

Please note that Apple does not support an official or standardized way of reading out sensor data in macOS (the only exceptions were the former model series officially declared as “servers”). Moreover, there is no documentation or other technical note about the individual function of the sensors. For this reason, the development of Hardware Monitor is very costly because the necessary data has to be determined by reverse engineering and tests run on a variety of computer models. Please support the development of the application by purchasing a registration key for Hardware Monitor.

Output and Processing

The applications support the following operations on the measured readings:

Additional Applications

The distribution package not only includes the full version of Hardware Monitor, but also two additional variants of the software:
