OS X Mountain Lion: Duplicate a CD or DVD
This article has been archived and is no longer updated by Apple.
You can make copies of a CD or DVD and the information it contains. To do so, use Disk Utility to create a copy, or “disk image,” of the disc, and then burn that image to another disc.
To burn a disc, you need an optical drive in your computer or connected directly to your computer. You can’t burn a disc using a remote optical drive.
