command to quit an app from Terminal

Might ask about the command in the OS X forum...

But try opening the activity monitor, and force quit it from there. It's in the Utilities folder.

First you need to find the process ID (PID) for Final Cut Pro:

ps -aux | grep Final\ Cut\ Pro

Check the STATE of the process. If it says E, it means that the process is trying to exit. For a list of the diffterent PROCESS STATE CODES, have a look here: http://unixhelp.ed.ac.uk/CGI/man-cgi?ps (or do "man ps" in Terminal)

You can try killing the process, by typing this command (replace # with the PID of Final Cut Pro):

sudo kill -9 #

If that doesn't work, there isn't much else to do. Quit all other applications, and try doing a forced shutdown by typing this in the Terminal:

sudo shutdown -h now
