IM running Kalyway 10.5.2 and after about a week the time machine, wifi, bluetooth and eject buttons all work but the menus that appear after clicking on it are all greyed out and nothing can be clicked. The menus still function eg. i see time machine backup and wifi will pick up new networks but i just cant select anything. Though if i got into system pref's i can manage most of it from there. Im also looking to update to 10.5.5 and get my other core working (Intel E5200 O.C 4Ghz)
Any info on this would be greatly appriciated
