I bought a 4th gen from Apple as a refurb, and I'm unable to load photos or album art. It shows up on my wife's Powerbook, but my photos and music library aren't there, they are on my ibook.
I've done everything on the Apple site regarding this, but no go. I've reinstalled itunes, updated, and reset. For some reason, I couldn't get itunes to reinstall from the .dmg I downloaded either, and had to get it off the pb, which as I mentioned, has no problem with the photo tab not being there.
I've deleted the ipod.plist, copied the command from the Apple site into terminal, reinstalled itunes, but it refuses to show up.
Just a note. There are a few threads related in the Apple discussions, but no answers.
