I'm not able to adjust the brightness on my computer anymore. I have a wireless keyboard and mouse hooked up to my mac mini which is hooked up to a 27'' thunderbolt display. I'm using the F1 and F2 keys but it's not working. I'm also trying to look for the slider in the display menu bar but nothing!!! Please help!
i had the same issues too....
not only does the brightness button dont work anymore, the ports on the display dont work too.
also... the spekers and Facetime HD camera dont work too.
