Hello all, new to this forum. Received my first Mac laptop on Monday and the data was transferred by the Apple store yesterday. One thing that they indicated was that when I first connect my iPod to it (which was originally setup on a Windows XP machine), it will ask to reformat the iPod and then all I need to do is resync the songs and all will be good to go. When I plugged it into the new macbook, because I had the Windows based iTunes set to manage manually, it didn't ask for any reformatting or resyncing on the mac as it carried over the itunes setting from before. It connected and displayed the music/playlists. I tested by dragging and dropping an album that was not on the iPod and it worked perfectly. Sorry for all the detail, but know I'm confused as to whether I should set the iTunes to sync upon connection and reformat the iPod anyway or just leave it as is. Does "if it isn't broke, don't fix it...." apply here? Any recommendations?
