I may be the last person on the planet to get an iPod ...so installation of iTunes is something I am only now experiencing for the first time. Should be easy, right? Well...not yet. My new 4th gen. iPod requires iTunes 8 or above. I downloaded 8.2 to my Mac mini...but keep getting the message that I must exit iTunes before installation can begin. I have exited iTunes...but it won't believe me and quickly drops me out of the "begin installation" window. I'm sure it's "me" doing something wrong rather than "it"...but I am at a loss. I'd be grateful for any suggestions. thanks.
