When your Mac unexpectedly tells you that you have to restart, that's a kernel panic.
There are few things more terrifying when using a Mac than the dreaded kernel panic. A kernel panic occurs when your Mac runs into a problem that is so serious it is unable to continue running. When it happens, your Mac displays a dark grey screen with the words “You need to restart your computer. Hold down the Power button for several seconds or press the Restart button.”
The only way to fix a kernel panic is to do exactly that and restart your Mac. Fortunately, kernel panics are very rare these days and when they do occur, restarting your Mac may be all you need to do to never see one again.
If you suffer repeated kernel panics, however, you’ll need to investigate the cause and solve the problem — it could be a conflict between poorly written apps or services, or a problem with hardware. Software is the most likely culprit. But thanks to apps from Setapp, fixing problems with software and avoiding kernel panics is very easy.
