As a result of I have been utilizing Linux for such a long time, the command line is second nature to me. I do know which instructions I must do sure issues — and so they by no means fail.

Positive, you could possibly at all times use the Pressure Stop software (from the Apple menu within the high bar). Or, you could possibly use the kill command.

As a substitute of doing a tough restart, I used SSH to log into the machine, find the problematic app, kill it from the command line, and my GUI got here again to me.
Earlier than you’ll be able to kill the app, nevertheless, you will need to first find its PID (Course of ID). To try this, situation the command:

And there you’ve gotten it, my pals: the primary 5 instructions I imagine each MacOS person ought to study. That does not imply you have to study them. However if you wish to get probably the most out of the working system, this can be a good spot to begin.
