I just had the hard drive of my 27" iMac 2.8 GHz Intel Core i7 replaced by my local Apple store (original drive died after only eight or so months). After a successful Time Machine restore I connected my 2nd Gen iPod Touch, and... nothing. No automatic iTunes launch, and after a manual iTunes launch, no recognition of the iPod. The iPod does show it's charging, and I've connected the same iPod to my Mac at work (works fine there). I reset the iPod just to be sure, but it made no difference. It seems that either something is missing in my new set-up, or some setting needs to be changed, but... what? I'm totally baffled what to do next. Everything else about my restore seems to be working perfectly, this is the only glitch (so far). Any suggestions? Thanks!
