I have not been able to use my touch for weeks now because of this. iPod worked fine before time machine restore, afterward it never was recognized in itunes. I tried EVERYTHING, but restoring it just does not work on this iMAC have restored it on another computer, and a apple store genius even restored it on his macbook, however on this computer it fails to mount or restore, i tried all the fixes and its impossible.The cable is good if I restored the ipod with it on another machine. Im at wits end here, what can I possibly do now? Bring my iMac in to prove that it will not mount on this machine specifically? Just to get my touch to work again?
