Ever have a problem with a CD/DVD stuck in your offline MacBook Pro and it doesn't allow you to boot up OS X? Apple mentioned the solution is to press and hold the trackpad button when booting your MBP. You tried that, but still fails? Another possible fix is the credit card/knife trick that sometimes works, but it just sounds not right?
OK, now there is an easy way to do it: Just power up your MBP and leave it alone for about 10 minutes. It will eventually boot up and the CD/DVD will automatically eject (make sure your power cable is plugged in, though!).
Stuck CDs should be ejected in terminal with
drutil tray open
drutil tray eject
