See my sig for iMac specifics. I want to record on CD some of my iTunes collection. I'm not sure what type of CD's to buy. I would like to play them in typical car CD players and portable CD players. I've looked & can't find info on what type of recording this iMac can do. Whether it can use CD- RW or not (guess I would hope it could do that much). Yet, I understand that typical car CD players can't play CD-RW only CD-R correct? Can anyone give me some info on what the CD capabilities are with this system and what type of CD I need to play in cars/portable players?
