There are certain programs that I always run that interrupt the shutdown process. When I try to shut down my laptop a message pops up saying that a program interrupted the shutdown process, but when I check the program it is already shut down. These programs probably just take a little longer to shut down. Is there a good way to shut down OSX without having to deal with these interruptions?

You can use sudo shutdown -h now in you terminal. The shutdown program sends the SIGTERM and after some time SIGKILL interrupts to all running programs. So shutdown should not be interrupted.

a quick shutdown shortcut is pressing the "control" + "option" + "command" + "eject" buttons simultaneously.

I thought this was just a shortcut for the usual Restart command (the same one found in the  menu)? – Blacklight Shining Sep 27 '12 at 11:09

sudo shutdown -h now
