Intel

macOS 10.13-10.15

(High Sierra, Mojave, Catalina)

  1. Download and run the installer package.
  2. During installation, select your desired driver - the "overclocked" driver will guarantee smoother inputs for certain tasks.

On an older OS?
Versions before High Sierra can grab the source (or a pre-built passthrough-kext) at the source repository.

Troubleshooting: Adapter Not Detected

  1. Reboot your machine.
  2. Some adapters have a switch for Wii or PC mode. Make sure yours is in Wii mode.
  3. Depending on what app you're using, you might need to plug in the adapter before opening the app.
  4. Monterey/Big Sur:
    You may need to unplug your adapter and then plug it back in to get it to register.
  5. Catalina/Mojave/High Sierra:
    Check your /Library/Extensions folder to ensure the installation went correctly. You should see a GCAdapterDriver extension in there; if not, re-run the installer package.
