Arggh... Got my new MPPro early today...several days ahead of schedule. I wiped the drive, installed a fresh and lighter system and set of apps. That completed, I kept the corner of my eye on a firewire based migration from the my old laptop. Success there, and I start to get complacent. Here's where things go south. As I went to install the very affordably priced 8 GIG updgrade from OWC...I did two foolish things. I worked in a hurried fashion and I seriously underestimated how much focus was needed to attend to Apple's miniscule screws that secure the back of the unit. (I have 49 year old eyes) The RAM installation went fine, but I in the process I lost one of the screws and a couple of the other screws don't seem to have a flush fit. It appears there was more to attend to than I realized. So tomorrow I'll have to do some research about what went wrong...and try to find out where I can snag one of those little bugger screws. Learn from my mistakes: Don't hurry, be ULTRA careful with those little screws....or you'll be me: A mac owner with a screw loose.
