The page provides instructions for what to do if you have a CD stuck in the superdrive of your laptop.
Eject During Boot Up
If you press the eject button, but the CD-ROM will not eject, try holding down the eject button as your Mac boots up (as it turns on after being shut down). If the CD still does not come out, you will need to bring your computer to Support Central for assistance.
Please note: Mini-CDs do not work in the superdrive of a mac. They will get stuck.
