Hi guys! Just got myself a rMBP and so far, it's looking pretty good. I actually upgraded from a mid 2011 MBA. The mid 2011 MBA was extremely silent; there was literally no fan noise, etc. when browsing the web... However, on my MBP, I can still hear a bit of noise even though I'm not doing much at all. Is this normal? Also, is there any settings that I should change, etc? I've never used a MBP so any help would be greatly appreciated. Finally, I actually purchased OSX Mountain Lion on my MBA, however, I am also covered by apple's "Up to date" program since I just purchased the MBP. How exactly does this work? Do I get Mountain Lion "key" which I can give to someone else? Or does nothing happen since I already purchased it? Thanks!
