Command To Shut Down Mac

Posted By admin On 19/01/22

This guide will explain how to shut down or reboot your Mac using the command line. This can be useful if you are controlling a remote machine via SSH, if you are in single-user mode, or if you are having problems within macOS and need to bypass the GUI.

WARNING If you are using your Mac remotely and you have FileVault switched on, ensure that you run the following command before restarting:

To open the dock menu, right-click on the application icon you want to shut down or click on the item and hold. Hold an Option (Alt) button, so the Quit menu changes to Force Quit. To shut down your computer without any prompts to save or closing out applications, press and hold the Power button. Save and Quit Before Restart/Shutdown To quit all running applications before shutting down your Mac system, press and hold Ctrl + Alt + ⌘ + Power.

This is necessary because FileVault requires that you unlock your Mac with your password before macOS loads at all — which, obviously, is impossible for a remote user to do. By running sudo fdesetup authrestart, this feature is disabled on a one-time basis.
