Finder on Mac Always On
Having Finder closed shouldn't cause any problems.

You can add a Quit Finder ⌘Q command to the Finder menu...

Copy and paste the following command into Terminal, then press enter.

defaults write com.apple.Finder QuitMenuItem 1; killall -HUP Finder


Note: When Finder is closed and an external disk is plugged in it will still be available to applications through the File > Open, File > Save, etc. commands.







To remove the Quit Finder ⌘Q command from the Finder menu...

Copy and paste the following command into Terminal, then press enter.

defaults delete com.apple.Finder QuitMenuItem; killall -HUP Finder








One of the nice benefits of having Finder closed, is it hides the clutter of files and folders I have on my Desktop. Sometimes I just don't want to be distracted by what's on my Desktop, so I quit Finder.
