When I try to log out on a Mac, I often get a message, such and such an application "interrupted logout". I would like to "force" log out, but I don't have administrative privileges. Since I don't have administrative privileges, I must go into the command prompt, find the PID of that application, kill the application, and then log out. This is very time consuming if there are, say, 10 instances of this application running. Is there an easier way of doing this, short of holding the power button for 5 seconds?
