My Mac is no longer seeing my ipod. It's a 2nd gen nano. I've had my mac in storage for a week or two, and when I set it up again, I was asked to update various bits of software, one of which was itunes, to the current version. I'm on OSX 10.4.11 Now, when I plug my ipod in, it reads that it's charging, but I don't get the 'do not disconnect' message, and it doesn't show on my desktop, anywhere else on my mac, or in itunes. What's going on...? I've tried doing some searches and done the appropriate checklist on the apple site, and the only thing I've left to try is doing a restore, which I'm loathe to do, as I'll have to back all my music up... Any ideas?
