My macbook pro for whatever reason has faulty USB ports (one doesn't work, one works half the time). It works with a mouse after repeated insertion, and with my old ipod it used to take a few tries to connect, but eventually would. With my new 4s though, it charges but won't show up anywhere on my macbook for syncing and downloading no matter how many times I retry. This is of course a pain in the butt, as I bought the phone with 64 GB to double as a new ipod, which is hard to use when I can't sync any of my itunes to it. I do have access to other computers with itunes, and have tried connecting through sharing to no avail. Also tried looking into a 3rd server like icloud to be the go between the computers but couldn't find anything. The itunes provided wireless syncing is obviously not an option because it requires being synced physically through the USB to start with Please help. I've tried everything I can think of. Thanks.
