How to Eject a Stuck DVD in a MacBook Pro
The DVD drive in a MacBook Pro allows you to burn and read DVDs, but over time it can run into technical problems. If your DVD gets stuck in the computer's disk drive, you won't be able to extract it or read additional DVDs. However, with a few simple shortcuts, you will be able to eject any stuck disks.
Open the Terminal application on your MacBook. You can find it in the Applications folder or by using Spotlight---click the magnifying-glass icon on the upper right-hand corner of your desktop and type in "Terminal" to load the application.
Type "drutil eject" (without quotes) into Terminal.
Press Enter. This will eject your MacBook's disk.
