How to Install

M1 + Intel

macOS 11.0+

(Big Sur, Monterey, Ventura, Sonoma)

  1. Download and run the DMG. Follow the instructions correctly.
  2. Start the app (it runs in your menubar). Click the icon, then toggle the driver.
  3. If you're using a Lossless adapter, consult the F.A.Q below instead!

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.

This driver is 100% free, but if you'd like to show support, consider a small donation to a charity I started to help families in the DC Metro area that are battling childhood leukemia.

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.
