New Aluminum Keyboard up arrow key sends F6 also

Just started happening to me too - Up arrow also triggers F6, MBP with an external extended keyboard. Easy to confirm with the keyboard viewer open. Turning off + unplugging fixes it for awhile and then it comes back. Changing Input Source to US International had no effect. Will try contact cleaner spray next.

This issue has been driving me crazy -- it appeared in Windows 7 (bootcamp on my iMac). I changed the keyboard in the language/region settings, disabled sticky keys a thousand times . . . It wasn't until I downloaded Sharp Keys that I was able to tell exactly what the behavior was - that the up arrow was sending F6. Through Sharp Keys, I've reassigned F6 to be an up arrow (this disables F6, but oh well). Seems to be working well enough for now.

What a bizarre problem. Interesting to see that so many other people have experienced the exact same thing.

All these years later - same problem. has anyone found a fix?

Same issue, I just moved and now my keyboard keeps opening Notification Center (F6) when I press up. So annoying... changing Keyboard in input sources changed nothing.

I think I have the solution:

In system preferences I had an Alert icon next to some of the categories in the Shortcuts side menu on the Keyboard settings. This was flagging conflicting key combo shortcuts. Upon resolving the conflicts, the up key was no longer triggering F6.

Hey everyone.

Its 2016 and this problem still persists. I used to use the Apple Aluminium keyboard on Windows and there I managed to work around it by using a software hack (ScanKey) to disable the F6 completely (and remapped it to F13). Now, however, I'm back to using a Mac and just recently this BS started happening again.. my keyboard is brand new, two weeks old. I accidentally discovered that if I toggle the option "Use all F1, F2, etc. keys as standard function keys" in Settings / Keyboard, the up key/F6 anomaly stops happening.. it does reoccur in time, unfortunately, but sometimes this "fix" will last for days, even weeks.. then simply toggle it again. Not a permanent fix, but much better than rebooting and hoping it will go away 😀

Actually,

scratch the above "fix".. it stopped working as soon as I posted it, LOL. I did some digging and it turns out there's a nice utility for OSX called "Karabiner".. I've used it to successfully filter out the annoying F6 from Up-Key presses (and remapped the F16 to stand-in as F6).. here's the private.xml for Karabiner to accomplish it:

<item>

<name>Disable F6</name>

<identifier>private.disable_f6</identifier>

<autogen>__KeyToKey__ KeyCode::F6, KeyCode::VK_NONE</autogen>

<autogen>__KeyToKey__ KeyCode::F16, KeyCode::F6</autogen>

</item>

I have same problem too.

Just hold Esc key when using arrow keys. Think Different.
