    Hello,

    Need your help

    I have a 2009 20inch Imac, and after latest updates the brightness control does not work.
    Display is like at 70% of its max but when i change the brightness through the wireless keyboard or through display settings the actual brightness stay the same.

    Did the reset smc thing but its the same.

    One thing works is an application to dim the brightness of the screen, but i cannot add more brightness.
