    Had a quick search and couldn't find info, apologies if I missed anything. My screen brightness on my macbook is locked for some reason. Anytime I try to brighten the screen with the f5 or f6 keys the brightness thing pops up on screen but there's a symbol underneath indicating that its locked. Anyone know how I can sort this out its becoming a real pain in the a$$

    Yeah tried that. Used to happen the odd time but seems to be constant now.

    You might try resetting your Mac's NVRAM

    Does the problem persist when/if you connect a different keyboard?

    I'll try resetting the NVRAM and report back.

    Don't have another keyboard to check if it still happens with external keyboard

    Tried resetting NVRAM there and it didn't make any difference

    It's very late here and I completely missed this. The F5 and F6 keys are used to adjust the keyboard backlight brightness. F1 and F2 control the screen brightness.

    Thanks for that. Now for my next question, does anyone know how to unlock my keyboard brightness keys? ;)

    What specific model do you have? Not all Mac notebooks have keyboard backlighting.

    I have the first unibody Macbook. Just checked it again there, it seems if I cover the light sensor it unlocks the brightness buttons but if its too bright it locks them up. News to me. Anyway thanks for all the help, apologies for the mixups, I blame it on the Friday factor.

    One more thing... check your System Preferences to see if setting keyboard / screen brightness automatically is available and enabled. If it is, turn it off.
