    I noticed this evening that the function keys on my Macbook pro have stopped working. I can no longer use them to; change volume, change brightness of screen and brightness of the keys. The applications f keys however do still work, so if I hold down 'fn' I can still use the keys as 'F' keys, i.e f2, f3, f4 etc. they just don't work for volume etc.
    This evening I also uninstalled a program and I'm pretty sure I only wiped the stuff off my Macbook that was related to that program, but the only explanation I can think of for the keys not working is that I accidentally deleted a driver or something for them? Ive searched through loads of forums and no one else seems to have had this problem, selecting the "use all F1, F2, F3 keys as standard function keys" is unrelated to this issue as I can still use the F keys.
    If anyone can help me in any way it would be much appreciated.

    If you frequently use the alternate function of a function key, you can switch the keyboard so that the function keys perform the alternate function without your pressing Fn. You then hold down Fn to use a function key’s original hardware control function. If your keyboard doesn’t have an Fn key, try holding down the Control key.

    Choose Apple menu > System Preferences, and then click Keyboard.
    Select the “Use all F1, F2, etc. keys as standard function keys” checkbox.

    ------------------------
    In your case: Do not select "use all F1, F2, F3 keys as standard function keys".

    Hi,
    Thanks for the advice but function keys dont work at all for volume, brightness etc regardless of whether you are holding 'fn' or not. My keyboard setting screen is also missing the illumination section (see attachment) which makes me think there is definitely some sort of driver missing. do you know where i can reinstall software from for mac keyboards?
