I'm used to disc burning utilities that have an obvious, explicit command like 'Burn ISO Image to CD.' To make life even more confusing, OS X's Disk Utility does have a Burn command, but it becomes disabled when you click on the blank disc you'd like to use for the burn. If you want to try out a new Linux distribution, for example, chances are you'll need to download a disc image in ISO format and burn it to a blank CD-ROM or DVD.īut ever since I began using Mac OS X, I've been perpetually confused about how to burn ISO images. Disc images are a fairly common packaging standard for large software programs.
