Q: Brightness-Keyboard Illumination-Mission Control keys not working
-
Mar 10, 2014 7:15 AMby sterling r,Hey there,
It souns like you have some keys that are not working as expected on your built in keyboard. I recommend these steps from the article named:
One or more keys on the keyboard do not respond
http://support.apple.com/kb/ts1381
- If the function keys on the top row of the keyboard are not working as expected, see Mac OS X: How to change the behavior of function keys.
- If the issue persists, use Keyboard Viewer to help isolate the issue:
- Click the Language & Text pane (Mac OS X v10.6) or International pane (Mac OS X v10.5.8 or earlier) in System Preferences.
- Click the Input Sources tab (or Input Menu tab in Mac OS X 10.5.8 or earlier).
- Click the Keyboard & Character Viewer "On" checkbox to select it (click the Keyboard Viewer "On" checkbox in Mac OS X 10.5.8 or earlier).
- From the Input (flag) menu, choose Show Keyboard Viewer.
Thank you for using Apple Support Communities.
All the best,
Sterling
