Good to hear others are using Mac to record. I have a 2000(year) G4. I was very happy with Sound Jam to make mp3 files of my playing or from a CD. Then came OS 10.4 update. iTunes took over, lost Sound Jam. I went to Audacity to do recordings and make mp3 files. Still not sure about how iTunes manages the sound files. But Audacity is great for me . Recorded Mardi Gras Song on the accordion and tin whistle with Audacity, works great.... Ed
