macOS 10.13-10.15

This release is a 1.0 release, and includes a signed kernel extension driver for macOS 10.13-10.15. This release supports both "pass through" and "overclock" modes.

Notes

  • This release includes a signed version of SmashEnabler by jackoalan, which can be used for adapters that don't support higher polling rates. It is functionally no different than the existing SmashEnabler, but renamed to GCAdapterDriverPassThrough to avoid conflict with existing installations.

macOS 11.0+

This release is a version 1.6; prior version numbers were lost in a battle with notarization and systemextensionctl. This release does not have an "overclock" ability yet, but should suffice for some users (overclock will come in an update).

Installation

macOS 10.13-10.15 users (High Sierra, Mojave, or Catalina - Intel only) can run the Package Installer. It will guide you through installing the driver; you may need to reboot afterwards. This Package Installer will not work on macOS Big Sur and M1 Macs.

Big Sur (11.0) users can download the .app.zip. Put the app in your Applications folder, run it, and check your menu bar for a small icon. Clicking it will reveal a popover for GCAdapterDriver that can be used to toggle the driver.

Unsigned extensions can technically be loaded on Big Sur still, for those interested in "overclocking", so preview/developer versions of these are supplied in this release for those wishing to test or debug. This does mean you will need SIP disabled (generally csrutil disable && csrutil enable --without kext in Recovery Mode) - but this lessens security, and you should be aware of what you're doing before running those commands.

Running the kext on Apple Silicon Macs

If you don't need overclocking, you should run GCAdapterDriver.app.

If you want to try the kext on an Apple Silicon Mac, you need to grab the ARM build/developer preview below. Do not install the Intel build. Note that kernel extensions are different on Apple Silicon machines - it involves extra steps in Recovery Mode that are not covered here.

IMPORTANT NOTICE

Kernel Extensions are a weird art in macOS. If you choose to manually install this extension on macOS 11.0+, or with a mismatched architecture, note that we're not responsible for whatever goes wrong. If you wind up in a strange state and need to recover, booting into recovery mode and running one of the following:

  • rm -rf /Library/Extensions/GCAdapterDriver.kext
  • rm -rf /Library/Extensions/GCAdapterDriverPassThrough.kext

And then then rebooting into normal mode should put you back at your original setup.
