i bought a new computer running 10.5 and moved all my songs from my ipod (which was previously syncing with a computer that had 10.2) to the new computer and started syncing with the new computer. turns out the new computer was faulty and i had to send it back until a replacement arrives. now, for lots of reasons i wont get into, i want to sync my ipod with my old computer, but when i plug it in nothing happens...anything i can do to get it to sync with the old mac again?
