Hey guys, I've had a Rev B (1.6, SSD) since last november. It's been running fine until recently when it seems to be having some of the problems that the Rev A's had - CPUs maxing out while watching video, heating up more (going over 80C, which it rarely did before), fans more often going to max. I tried to install the latest version of coolbook but I don't think it may be compatible with either the latest OS X update, or with some other software update. I'm also wondering if the issues have anything to do with the little MacBook Air SMC Firmware Update 1.1 that I recently installed. So, my question is, does anyone know how to roll back or undo those updates? Also, anyone having similar issues with their Rev B? Much thanks.
