How do I copy or duplicate a CD/DVD on a Mac using Disk Utility?
This method involves the creation of a Disk Image. A disk image is an exact binary copy of an entire disk or drive. It is not just a collection of files or folders but is an exact duplicate of the raw data of the original disk, sector by sector. You can make multiple exact copies from a disk image. 1. Launch Disk Utility. Disk Utility is found under Utilities in the Docks Apple menu. 2. Insert the CD or DVD disk in your computer’s optical drive and select it in the list of disks and volumes on the left. 3. In Disk Utility, click on New Image. Type a name for the disk image and choose an image format. 4. Click Save. (This will save a disk image file with the extension .cdr. This disk image will then be listed in Disk Utilitys left column) 5. When creating the disk image finishes, eject the original CD or DVD and insert a blank CD or DVD. 6. Select the disk image in the list and click Burn.
