The Setup 17" iMac with all media on it. MPB with no media on it. 250Gb HD with a full back up of the iMac on it. I'm going home for a week from uni and I'm taking my MBP and my HD. How do I set it up so I can access all of my iTunes folder on my external HD without copying it to my MBP? It'll only be for a week but I don't really want to take my iMac home with me for something that can probably be solved.
