I have 11.6 MBA for myself And my wife has 13.3 MBA for her. Our boot up times are dramatically different... Mine boots up in 11 seconds or less, but hers boot up in like 22-23 seconds. I did reset Pram on her MBA, but it doesn't improve anything... It used to be like less than 15 seconds. I am not sure what happened. All I did was install updates from apple and iwork on that laptop. Any suggestions? Help???
