How do I open the CD drive? 

The Studio Mac has an external Blue CD-R/RW located below the Pro Tools interface. Use this drive to read or write CDs.

To open the CD drive when it's empty, press the button on the front of the drive. Press the button again to close the drive.

To open the CD drive when there is a disc inside it, drag the discs icon on the desktop onto the trash can icon in the dock.
