MacApper has a nice rundown of 4 popular disc burning utilities for the OS X platform. They range from free options to $100, and impressions are given on each application. Useful review if you’re looking for a program to handle disc burning activities above what OS X offers you.
I’m partial to Disco, and am loving the newly released 1.0 version. Roxio – in my opinion – has been hanging on by a fingernail…Their weekly $20 off/$30% off/Save Now! emails for Toast have seemed needy to me for some time. But I’m sure there are some good features in there that merit a $100 price tag.
Whichever end of the spectrum you choose, you’re likely to find a good solution for your burning needs (or desires).
