Can't open or quit Finder I'm trying to open Finder, but every time I try I get this error message:



I've tried restarting my Macbook Pro as well as doing a "Relaunch" from "Force Quit Applications":



However, nothing happens when I try to force-quit the application, so I'm 'stuck' with a non-responsive Finder. How can I fix this?
Try this in a terminal window:

killall Finder


or even

killall -9 Finder
