    I just purchased a 2009 21.5" iMac, specifically model MC413LLA. Does this model have a self adjust auto brightness sensor like how macbook does? Like when the light in the room is on it should turn the brightness up and turn it down when the light is off..

    I read that theres suppose to be some kind of setting to set in system preferences but can't find it..
