-How to Burn a disk image on a Mac creating a copy of your disk is a great way to make sure you don’t lose that precious DVD, video game, or music CD. Burning the disk image (otherwise known as a .iso file) is great for backing everything up.
-However, it can sometimes be a bit confusing as to what to do with this ISO file when you have it… so here’s how to get the ISO onto a blank disk using only a Mac and no other software.
-Step 1 When you have the ISO copy of the disk on your computer, insert a blank disk into your disk drive (Make sure that the disk is large enough for the ISO, as some disks can be as large as 3 or 4 gigabytes.)
-Step 2 Open the Disk Utility. Simply searching for “Disk Utility” in the Finder will usually bring it up without a problem.
-Step 3 In the ‘File’ menu, choose ‘Open Disk Image’ and locate your .iso file. Open it and it will appear on the left-side menu. Select it and click the ‘Burn’ button in the top menu.
-Step 4 Follow the simple instructions presented to you after you select the burn function and wait.
-And that’s it! You’ve just made an exact copy of your disk!
