TG PRO: STAY ALERT TO HOT FANS AND HOT CHIPS ON A MAC

Apple includes many hidden thermometers in its Macs and a tachometer for models with one or more fans.

 In normal usage, you may never give a thought to how hot your performance cores are or how fast a fan is running. But we live in times of extreme temperatures, and some Macs-particularly Intel models-run hot already.

TG Pro (fave.co/3PRZNAF) exposes low-level information Apple tracks and lets you set alerts in case values exceed what's considered safe for long-term operation. You may want to have a fan or fans kick in sooner or faster than Apple's default behavior or run your Mac cooler to preserve its longevity.

You can view current information via a lengthy dropdown system menu you can customize to reduce the number of entries.

Its menu bar item provides a concise summary you can tweak to show the highest or average temperature across all sensors, among other choices. You can also bring up the app's sole window to view a graphical display of regularly updating temperature information.
