Apple - SuperDrive stuck disc
How do I force eject a CD from my Apple SuperDrive?
Press the eject key in the top right corner of the keyboard. ( Not present in a macbook air)
Drag disk icon from desktop to trash can.
Right click on disk icon and click eject.
Use disk utility to manually force unmount the inserted disk from within the superdrive. This will cause it to eject. Score 4.
Restart your Apple computer with a corded mouse plugged in. Upon start up, hold down all the mouse buttons. It's a built in force eject. If the disc doesn't come out, you have a physical jam of some ilk and you'll need professional help.
