Force quit shortcut not working

Does the Apple menu approach work?

How about option-clicking the dock - does that work?

Does the shortcut fail to work in Safe Mode (Mac startup key combinations)?

You can always force quit the macOS by holding the power button/TouchID for ~6-10 sec.

reboot as normal

Log out, sleep, wake, restart or shut down your Mac
