Last month my iPod Touch synced automatically when i connected it to my computer (PC). Now, whenever I connect to my new computer (Mac) it synced once, then it never worked later. When I got a Mac, I downloaded the latest version of iTunes to see if that was my problem, but still nothing. I've tried restarting both my computer and my iPod, but it made no difference.
Anyone who knows how to fix this problem please reply.
