SystemLoad for Mac helps you diagnose cooling and power supply issues before they become major problems. Straightforward and streamlined, this app is not limited to tech experts but can be installed by any Mac user who wants to test out his or her processor.

SystemLoad for Mac installs quickly and greets you with a straightforward interface that allows you to easily generate additional processor load by using a drop-down box and a slider. You can choose how many processors to diagnose, as well as how much of a load to give them. Also, you can put a constant load on processors or play with the voltage supply circuits. Once the app is up and running, you must launch the activity monitor in OS X to view a graph with each processor load and test cooling and power supply viability. If you're not sure how to interpret the data, the Help section accessible through the app menu will no doubt come in handy.

A capable processor diagnosis tool, SystemLoad for Mac is useful if you want to check the performance of your processor and ensure that the cooling fan does its job. The app is easy to use and stable, making it a good choice for any Mac user.

Full Specifications

What's new in version 4.1

  • Added full menu controls and keyboard shortcuts for all features of the application.
  • Added Touch Bar controls for all features of the application.
  • Added new status line that shows the number of available processors on the tested Mac.
  • Configurations where processors have been deactivated via operating system settings are now supported correctly.
  • The application now disables sleep mode while running and declares itself as needing real-time performance. This improves the accuracy of results on battery-powered Macs and in situations where multiple applications are competing for processor access.
  • Corrected a problem where the search for updates always returned an error message.

Developer's Description

SystemLoad is a diagnostic application assisting you in the detection of cooling or power supply problems with Apple Macintosh computers. The tool can put a user-definable load onto one or more processors. This can help in diagnosing the following issues: problems with the cooling system or temperature sensors, problems with chirping noise caused by oscillating parts in the voltage supply circuitry of specific computer models, problems with battery units of portable computers.
When desired, the tool can put the processor(s) under the maximum load possible, generating the highest possible temperatures and highest load on the power supply. This way you can verify if all components (CPUs, sensors, cooling subsystem, power supply unit, battery unit) are working correctly when they are being pushed to their design limits. No installation is required, no administrator permissions are needed, nothing is changed in the operating system.
