EDIT: I’m a Linux Performance Engineer with 15 years under my belt and I use a Mac as my daily driver. Including when I gasp interface with Linux computers because it’s always a combination of ssh and configuration management of some form. Telling me that Mac users don’t use vim is, on its face, one of the dumbest things I’ve ever heard. It’s a text based interface. I could do it with Windows, but I’m faster on Macs.
:x also writes (same as :wq). :q! is force quit.
If you accidentally made changes then :q will give an error and :x will write those changes.
So :q! Is you safest bet if you need to gtfo.
