hey i need some urgent help - so here's what's happened.

My Nightfox was working beautifully with my Macbook Pro, connected via the stock USB-C to A cable at all times. Then I decided to flash it to tweak the layout of a few keys on Layer 1. After I flashed it, it would connect to my Mac and then disappear from the devices list. Now I can't get it to show up at all. I know the keyboard is fine cos I hooked it up to my Chromebook and it works as it used to ... so why is it suddenly not playing nice with my Mac?

Help! I sold off other keyboards so this is my current daily driver, and it can't work at all!

Have you tried different USB ports on your Mac?

Did you use the client-side configurator to flash the keyboard (or the web ui)?

Also, which Macbook Pro do you have?

I tried all the USB ports on my Mac. I used the client side Kiibohd configurator, not the web in-browser one. I'm using a late-2011 17" Macbook Pro.

It works completely fine on my Chromebook Pixel though! And I just managed to get intermittent connections on my Mac.

it will show up for a minute or so and work, and then it will disappear. I've noticed that sometimes, in Karabiner Elements, it will remain in the devices list but not work at all. Other times it will just disappear and never come back.

ok, it was working for five minutes or so, and then keystrokes will start to lag and then it will stop registering completely, or to the point where it is unusable. In Karabiner Elements I can see multiple instances of "product": "Keyboard - WhiteFox:truefox PixelMap USB" showing up.

thing is, it was working fine for months! what happened when I flashed it? I used to flash it with only the keyboard connected, just now I flashed it with the mouse connected as well. that might have affected it somehow.

NKRO keyboards don't work well with the USB Overdrive and Karabiner as they apply a lot of "hacks" to the system and always expect a 6KRO keyboard.


  • Force the keyboard to run in 6KRO mode (you can test this by using the 6/N-KRO key)
  • Uninstall Karabiner (and USB Overdrive)

thanks @HaaTa. I didn't have USB Overdrive installed but uninstalling Karabiner seems to have worked. I do need Karabiner installed to make this keyboard work across all my devices, so I'm gonna try with a clean install and see how this plays out. Thanks anyway! sorry for the panic.

sorry, i spoke too soon ... after uninstalling Karabiner the keyboard will work for a while and then just go off the grid. Sigh.

That sounds like a bad USB cable (or a dirty connector on your Macbook Pro). I'd try a new cable and cleaning out the USB port. You may also want to clean the Nightfox USB connector with some isopropyl alcohol sometimes some flux gets on the connector pins which may cause packet dropping.

i'm sorry HaaTa but I doubt this very much. When the keyboard goes off the grid, I will unplug it and use the same stock cable and plug it straight into my chromebook, and it works flawlessly. All the USB ports work with my mouse all the time. There's something finicky about the PCB, I believe.

So try plugging it into the chromebook and wiggling the cable to see if it still types. Generally if it's working with one computer, there's usually an issue with the computer itself (or the connector). Also, do you have the ability to try with another Mac? Have you tried 6KRO mode?
