Play CDs and DVDs on Mac
If you connect an external optical drive (for example, an Apple USB SuperDrive), you can play CDs and DVDs to listen to music, watch movies, or access files that were backed up on a disc.
Turn the disc label so it faces up or toward you.
Insert the disc into the optical drive until you feel the drive catch and pull the disc in.
You must insert the disc nearly all the way in before the drive pulls it in.
If you’re using an Apple USB SuperDrive, it accepts only standard 120-mm (about 4.72 inches) round CD and DVD discs. Don’t insert smaller or irregularly shaped discs, and don’t insert a disc with anything hanging from it (for example, a cleaner disc).
