Sorry if the title is confusing. Anyways, I want to do 2 things: 1) I want to transfer my iTunes music on my PC to my Mac. I was thinking to just burn a cd and then transfer them to the mac this way. It seems easy. 2) When I plug my ipod into the mac, nothing shows up. I want to be able to buy songs from iTunes on the Mac and transfer over to the ipod. And I want to be able to buy songs from itunes from my PC and have those songs also go to my ipod. Basically, I will be using my ipod on 2 computers. Thanks!
