Well, I've tried a number of different options to get this keyboard to possibly work on the Mac. Thus far it's thwarted me. I've tried the USB -> PS2 adapter, which is then fed into a PS2 -> USB adapter. That didn't work, unfortunately (though it did with my reaaaaaaaaaaally old keyboards that I have in a box). Next up was a driver that was made for the Noppo Choc keyboard that I had hoped I could get to work with the board itself, but it seems that the automatic scanning does not work and thus it's not detected. I'll open a ticket on the GitHub site and see if there's anything that I might be able to do that's beyond what I've done. It's a great little board though. I'm using it to type this (from my PC) in fact.
