Some FN keys do not respond

[erdeminanc]

Hi everyone,

I recently use an iMac Late 2009. I accidentally installed Developer version of 10.7.2 Mac OS X Lion, considering it is the official one. After giving it a look on the net, I found a way to go back to 10.7.1. After that I installed the official one. No problem till here.

The keyboard issue began after that. F1,F2,F3,F4,F5,F6,F7,F8 and F9 do not respond. I checked it using virtual keyboard on MAC and I can't click on these buttons on the virtual keyboard as well.

Yesterday, I upgraded my iMAC to 10.7.3, but nothing changed.

So any suggestions for the issue?

I don't know if this will help, but try installing the 10.7.3 Combo update if you haven't already. It will contain the proper files for 10.7.1, 10.7.2, and 10.7.3 in it; maybe that will fix your problem.

Thanks for your help, I just tried that, but the problem still exists.

Did you try configuring your keyboard in system preferences? It's in keyboard, then the keyboard tab (when it's not already on that) and then the button, change keyboard type.

Thanks for your advice. Just realized that, this might be the issue. I can't pass the step "changing keyboard type". it says " your keyboard is not identified."
