Endurance: CPU Stress Test

Endurance is a free tool to benchmark battery life as well as run CPU stress tests. 

To test battery life, it's as simple as clicking the start button and waiting until the battery has depleted to zero percent. Once that occurs, the total time that the Mac lasted will be available along with all the details in a handy CSV log file.

For testing the thermal limits of the CPU, again, it's as simple as choosing the number of cores to test (which is preset to the max number) and clicking test. The CPU will run at as close to 100% capacity as possible, which will provide an easy way to test how hot it gets and if the fans are working properly. No more opening up Terminal, typing in cryptic commands, or trying to find outdated apps to test the CPU, just use the free Endurance app!

There's no cost for Endurance. 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.

It's compatible with both Intel and Apple Silicon architectures so it's ready for all current and future Mac models.
