Symptom
Neither pressing the eject key nor holding the mouse button during startup will cause your audio CD to eject.
Note: This happens with audio CDs that are in undamaged, working condition.
Solution
Use the firmware update that has been released to fix this issue. You can download and install the updater from Software Dowload document 120212, "
Slot Combo Drive Update: Information and Download", or you can use the Software Update feature of System Preferences.
Note: If you have a slot-load optical drive that still has an audio CD in it and you are unable to eject the disc, you will not be able to run the firmware update. It is essential that the audio CD be removed before the firmware updater is run. If you cannot remove the disc, please contact a service provider for assistance.
