    I was messing around some files and deleted a few and i just noticed that now f1, f2 which turns brightness up and down dosen't work aswell as f10 f11 and f12.

    when i press the sound shortcuts nothing happened. however i am able to change the sound by clicking on sys pref > sound.

    any ideas?

    System Preferences > Keyboard > Keyboard > Use all F1, F2, etc. keys as standard function keys (uncheck)

    Did you try restarting your computer?

    PRAM Reset. Turn off computer, hold down the CMD+ALT+P+R keys, then turn it on. Release the keys after the second chime.

    Just Force Start your computer...

    ...by holding the Start key for 3 seconds. Then restart your computer. The brightness and volume keys should just reset themselves.

    :)
