I have just synced my new iPod nano with music from my old iPod but it won't recognise that it has the music
I have just moved my iTunes library from my MacBook Pro (2008) to an iMac (10.8.5) so that my new iPod Nano can be synced with my music. Although when it's attached to iTunes it says the music is there, when I try to play, the iPod says there's no music. What am I doing wrong!
iMac, OS X Mountain Lion (10.8)
