CPU Stress Tests solves the problem of having a way to test the thermal limits or battery life of a Mac. Instead of opening up Terminal, typing in cryptic commands, or trying to find outdated apps to test the CPU, it’s as simple as choosing the number of threads to run and clicking start. It will keep the CPU busy from a low percentage or all the way to 100% for as long as it’s needed.

Want 50% CPU usage? Choose half the number of threads compared to cores and click run. It’s easy to customize from between 1-64 threads. There’s no cost for CPU Stress Test. No purchase, no in-app purchase and no ads. We wanted to make a simple to use utility that was useful to the Mac community at large, for everyone to use.
