I just got a new unibody MBP (which is a sorely needed update from my Blackbook). I'd like to put the HDD from my Blackbook (500GB) into the Unibody and then sell the Blackbook with the 320GB drive that came with the MBP. I was all set to do so, but wondered if I would have all the correct graphics drivers for everything to work properly. I upgraded both systems to 10.6.4, so I would think things would work, but I googled around and found older threads to the contrary (http://forums.macrumors.com/showthread.php?t=755560). I don't really want to have to run out and grab an enclosure or have to do a clean install - I just want to pick up where I left off in the MBP. Would a straight-up swap work? Wouldn't it ask for a software update after I do it?
