Why won’t my Mac eject a disc?

Try any of these: If the CD or DVD is being used by an app: Close the app and try to remove the disc again. If you can’t close the game that’s using the CD or DVD: Close the file on the disc you want to remove, and then try to remove it again.

How do I force eject a disc?

Straighten out the paperclip until it’s at least 1 to 2 inches (2 to 5 cm) long. There should be a small hole right under or above the drive bay door, which is what “ejects” the disc. Put the paperclip through the hole in the pin and gently push it in.

Which is the eject key on a Mac?

This key is in the upper right corner of the computer, right above the number pad. If you have it, press it. It has the picture on the left. This key is great because you don’t have to choose the disc. Just press it, and the CD or DVD will come out.
