A few years ago, I bought an iPod Classic 80g that was loaded and formatted for Windows. I now have a Mac. My question is: Can I sync my pc-formatted iPod on my mac? I hook it to my iTunes, the mac sees the iPod, but I cannot synch. What do I need to do, if anything, to make it work? Or, do I need to buy a new iPod that is formatted for Macs?
