On the off chance one of you nice people might be able to help,..
I've had this intermittent problem for a few weeks now that's slowly getting worse and worst on my iPod touch g4.
It will charge fine on any usb supported equipment including tvs, ps3 and laptops etc, but when I connect it to my mac (with itunes) neither device sees the other. Tried different ports and updates but no joy.
The odd thing is the problem is intermittent. Yesterday I tried everything to get the ipod to sync with the mac and in the end, gave up and recharged the ipod on my ps3. On the off chance the ipod might work again after a rest, I tried again on the mac, but now its again failing to charge or sync.
Getting really frustrating now.
