After experiencing crashing and freezing on 15" MacBook Pro 2017 (macOS High Sierra), I started eliminating running programs that I thought might be causing the crashing as advised by an apple support employee.

I immediately suspected that it might be smc fan control (A program that hasn't been updated since 2016)

After removing the program I noticed that the problems stopped.

However it is useful to pre-emptively turn fan speed up before using a resource intensive program. My lap has also threatened to leave me if I don't resolve this issue.

Has anyone else experienced this or am I alone? Are there other alternatives for fan control in osx.

Here is a short list of apps that you can try. I've listed them by price (lowest to highest). All of them specifically state that they support High Sierra.

  • I tried Macs Fan Control (tended to make fan speed up and slow down rapidly. Then tried and bought TG Pro, which works well so far and has a flexible way to define rules to boost fan speed based on temperature. – RichVel Mar 30 '20 at 8:28
