I have a 2011 iMac and I want to boot into Windows 7 the 'restart and hold option' way. Was using bootchamp but if I use that then screen is at full brightness and unadjustable. It can get painful and makes the computer run hotter. The problem is I can't figure out when specifically to press and hold the option key on the wireless keyboard when restarting into the 'choose your OS' menu. My success rate is maybe 10%-- I've done it twice I think, the rest of the time I somehow miss the timing or press it before the keyboard syncs or I don't know what. Anybody who boots this way care to share when they actually press the option key? Like how many seconds after or before the Apple Chord plays? Or is there an easier way to get into Windows with the brightness controls working? It shouldn't be this hard.
Thanks!
Thanks!
