How to Copy a DVD on an Apple iMacby James Johnson ; Updated February 10, 2017
As a Mac user, you can easily copy DVDs using your Mac operating system's built-in software. You don't even need to have two DVD drives to complete the process, since your Mac will copy the DVD to your hard drive and then allow you to replace discs. You simply need to know the step-by-step Mac DVD copying procedure.
Place the DVD you want to copy into your Mac DVD drive. The Apple DVD player will launch in a new window. Close that window.
Click on your Mac's "Application Folder," and then go to the "Utilities Folder" and choose "Disk Utility."
Look on the left-hand side of the window that pops up and find your DVD drive; under that drive, you should see your DVD listed by its name. Click on "Insert DVD," and then, at the top of the window, click on "New Image."
Type the name of the DVD into the "Save As" box. Then choose the location where you want to save your DVD.
Under "Image Format," choose the "DVD/CD master." Under "Encryption," leave it set to "none," and then click "Save."
Wait for the progress bar to complete the process of copying the DVD, and then eject your DVD from the drive.
Select the DVD file you created. This will show up on the left side of the "Disk Utility" window below all of your computer's other drive options. The disk name you are looking for will include the DVD name and end in .cdr. Click "Burn" at the top of the "Disk Utility menu" or, from "File," choose "Burn Disk."
Insert a blank DVD and then choose the "Verify burned data" checkbox when the "Burn" window appears. Also choose your speed, which will set the burn speed time. Click "Burn" and wait for the process to complete.
