I would like for any opinions on what and why you consider your choice to be the best burning software out there for the mac. As I will be buying this with in the week any help is appreciated. I will be making backups, use on PC's, and Music CD's.
No disagreement here. But you might see if the built-in "burn disc" feature, and the iTunes "burn CD", can do what you need. They work pretty well for generic stuff.
If you want to do more complicated stuff, then Toast is the way to go. Make sure you get the Titanium version.
