10.6: A temporary fix for non-working F8-F12 keys System 10.6
Snow Leopard only hintIt's really been bugging me that, since updating to 10.6, my F8 through F12 keys sometimes won't work after a period of time. Recently someone told me how you can see when this happens.

Open Console, make sure the log list is visible, and then search for BUG in libdispatch using the search box. If you see this...

/System/Library/CoreServices/Dock.app/Contents/MacOS/Dock[1291]: BUG in libdispatch: 10C540 - 1676 - 0x4

...then you probably have non-functional F8 through F12 keys. To make them work again, open Terminal and type killall Dock and the keys will work again.

I didn't discover this myself, but though it worth sharing the solution.

[robg adds: I did a bit of digging with Google, and some other reports reflect that this may be restricted to those using the Chinese Input Method. I haven't seen it myself.]

Yeah, this bug has been hassling me and another friend since upgrading to Snow Leopard.

The same thing can be achieved by launching Activity Monitor (in the Utilities Folder) and quitting the Dock process.

Let's hope Apple fixes this one soon!

10.6: A temporary fix for non-working F8-F12 keys

I am posting this here because the subject describes the problem I encountered as well. Though, it may be different because the solution provided did not help me.

Recently I lost the function of F6-F12 keys on my aluminum keyboard.

After trying the above solution and another I found in Apple forums I played around with my Keyboard preference pane and fixed it for myself. At least for now.

In the Keyboard pref pane > keyboard tab, I checked the box "Use all F1, F2, etc. keys as standard function keys". I switched to another pref pane and then back. I then unchecked the same box. Now all the keys work properly.

What caught my eye in the first place was that the keys would work how "I desired them to" when pressing the "fn" modifier. I then realized that the computer was acting as if that "Use all F1, " option was selected. A faulty plist file?

I get this same error in 10.6.4 - and I use the Japanese IME (Kotoeri).
Running killall Dock in Terminal did indeed fix the issue. Thanks!
