    When I start up my Macbook in Verbos Mode it gets stuck at "Invalid firmware max backlight setting". Anyone can help me here ? the only thing that I haven't updated is my iTunes which is @ 7.5 (19). And I just updated with the Airport/Time Machine Update.

    try resetting PRAM. Hold Option-Command-P-R immediately after turning on power, and release it after it bongs a 2nd time.
