If you have a CD or DVD stuck in the SuperDrive of your MacBook Pro, give the above a try to see if it resolves your issue. Depending on why the CD or DVD is stuck, this quick tip may or may not work. If that’s the case, you might consider checking out the hints provided on the Mac OS X Hints forums (search for “stuck DVD” or some other similar search term). I’m not sure if this terminal command will work in earlier versions of Mac OS X. In any case, I hope this helps!

- If you are unfamiliar with the Terminal Application that comes installed on all Mac OS X systems, please check out the Apple Terminal page on Wikipedia for more information.
