Why does my new Mac mini M4 randomly restarting?

All lies... Those companies bad mouth EtreCheckPro, because we use it to ferret out their paid poorly made junk-ware that creates problems for Mac's.

EtreCheckPro is an excellent tool for finding and sorting out junk-ware problems.

Full Computer Sleep Mode can cause an assortment of different problems.

As a test:

Turn On "Prevent automatic sleeping when display is off"

Set "Turn display off when inactive" to 5 or 10 minutes

Leave the M4 Mac mini On and only allow the display(s) to turn Off

Do not manually select Sleep from the Apple Drop Down menu

Leave the Display on and allow it to go into standby mode

Only Shut Down the Mac when away for a day or more

Happy Mini M4 Pro user here. Have had solid reliability here since it was purchased in early December. As others have suggested, testing sleep options may be a good troubleshooting step, and EtreCheck may reveal the issue. I can however say that I have had good behavior with Energy defaults:



I have not seen this issue. Test without using sleep. It only causes issues. Just have the display turn off after a set time. However, that being said your Mac should not restart on its own unless there is an issue. Also test without any external hardware connected like a drive or dock and test. Perhaps you should run the free app Etrecheck and review the results. You can even post here for review.

Can you run the free app Etrecheck and post here for review?

not true. I have this app for a long time and no issues.
