Using the Application

What is Hardware Monitor?

Hardware Monitor is part of an application suite for the macOS operating system.

The application makes it possible to read out available hardware sensors in Macintosh computers, to process their measured values, and to store them. This includes the following sensor types:

Moreover, the application can display additional technical information about your computer. Among other data this includes:

We try to access sensors on as many Macintosh computer types in the supported time range (see below) 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.

Additional Applications

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

Another application, the add-on Hardware Monitor Remote allows you to monitor remote computers as well, transferring the sensor data over a network. The following table summarizes all available variants of the applications:

Application Name Part of download package Description
Hardware Monitor Hardware Monitor main program with all features
Hardware Monitor Lite Hardware Monitor version running in the menu-bar only
Hardware Monitor Remote Hardware Monitor Remote “agent” program running on remote computers in a network
hwmonitor command-line tool Hardware Monitor version for the Unix command-line of macOS

Data output and processing

The applications support the following operations on the measured readings:

System Requirements

To use Hardware Monitor 5, you need an Apple computer which has one of the following operating systems installed:

It is recommended to update macOS to the latest version which is available from Apple. This can be done using the Automatic Software Update feature of the operating system.

Only Apple computers officially compatible with OS X 10.10 or later, and released before November 2016 are supported by Hardware Monitor.
