Official Nintendo GC adapter for OS X

[area]

Hi,

I'm the author of these drivers. If you just want it to work, download the DMG from https://github.com/area/osx-wiiu-gcc-adapter/releases and run install.sh with superuser permissions, and reboot.

The Mayflash adapter doesn't work natively on OSX either, just so you know (well, one port works, but not the other three).
