Ok, If I bought a New iPod Nano can I use my older Mac 10.2.8 that only has iTunes 6 on it? Or do I have to have a newer Mac OS with Tunes 7 or higher? I can't seem to find a place to upgrade iTunes with my current OS. I don't want to currently upgrade the OS on this Mac at this time. I just want to be able to put music into an new iPod Nano with this Mac, if possible...? Thoughts??
