I was updating my Macbook Air SMC to 1.8 today, when the white screen with the apple logo came up the macbook made really loud noise, sounds like the fan was running really hard. It stopped after the updating. Is it normal?😕

Yep, in fact it gives you a warning telling you it was going to do that before it does it

LOL. My Air is been silent because I don't push it I guess and when the update happened I went WOW I guess the fan works!
