When a disc won’t eject from your Mac, try the following:
1.) Press and hold the Eject key,
2.) Right-click on the disc icon on the Desktop and select “Eject” from the menu,
3.) Drag the disc icon to the Trash.
Launch Disk Utility (Applications > Utilities) and select the troublesome CD or DVD in the sidebar. Click the Eject button at the top of the window.
Launch Terminal (Applications > Utilities) and copy the following command: drutil eject
Restart your Mac and hold down the trackpad button as it boots up. Keep pressing it until the login screen or desktop displays.
Shut down your Mac, turn it back on, and let it sit for 10-15 minutes. Make sure the power cord is plugged in as you do this and the disc just might pop out on its own.
