I have to burn a OS install ISO for a friend who is upgrading his mac OS for the upcoming Diablo 3 release. Will my External hard drive and dvd burner work on a Mac? What is a good iso burning utility for Macs? My Mac xp points are pretty low/non existent so this is kind of a new area for me I assume it will be similar to other OS installs? and Drivers come prepackaged for his model? A relatively new mac laptop.
