Hi I just got hold of a mid-2010 MBP 2.4gHz I5, an upgrade from my 2.33 c2duo model, essentially I switched the Hard drives out putting my old system into the new machine, everything boots fine and it runs well, however my old machine used to boot up in around 22 seconds, (yes I used to time it!) now with the exact same system in my new machine it takes around 1m 40secs to boot, this obviously is counter intuitive and I wondered if there was something obvious I've missed...?
