I just got my refurbed 2.53 ghz MBP! Damn it's sexy... previously I had a White Macbook with a 500gb WD Blue drive in it. It's pretty full of stuff though not packed... well I've taken it out to put in the MBP but what do you all think I should do? Just put it in and run what I've had on there (FCE 4.0, Photoshop cs4, final draft, Vuze etc) and let the new MBP figure out the settings... or just start fresh from a new install of OSX? Come to think of it... will it even work since this drive is from an different laptop?
