Most people don't know how easy it is to copy a DVD on a Mac. It's actually quite simple and only takes a few minutes. Here's how:
1. Insert the DVD you want to copy into your computer's DVD drive.
2. Open the Disk Utility application, which can be found in the Applications folder.
3. Select the DVD disk from the left hand column in Disk Utility.
4. Click on the New Image button at the top of the Disk Utility window.
5. In the Save As: field, give your new image a name and choose where you want to save it on your hard drive. Make sure to select DVD/CD Master from the Image Format drop-down menu so that your new image will be an exact copy of the original DVD.
6Click on the Save button and Disk Utility will create your new image file.. This may take a few minutes depending on how much data is on your DVD.. When it's finished, you'll have an .cdr file that is an exact duplicate of your original DVD!
