I would be willing to sign the kernel extension if there is any interest. The alternative is to turn on kext debugging mode but that is undesirable for end users. As of 10.10 all kernel extensions (codeless or not) need to be signed by a paying developer. Now, there are problems with the codeless kext route. With the a codeless kext installed libusb is able to access the WUP-028 in the same way as is done under Linux. In this case we need to prevent IOUSBHIDDriver from loading as the HID report descriptor of the WUP-028 makes the device unusable (believe me, I have tried to get it working as a Joystick). They are specially crafted kernel extensions that prevent other drivers from loading. 4 New Mac update doesnt allow Gamecube adapterĪ change that referred to a codeless kext that allows the native GameCube adapter support to work was removed by MayImilae with the comment 'That is not native gamecube controller support, that's a system driver.' Thought I should make the comment that codeless kexts are not absolutely not system drivers.
