Due to an excess of caution, we have disabled Wireless Xbox 360 controller support as of 0.16.6.
This issue cannot be resolved with minor changes to the driver, and requires that the driver be re-written from scratch to resolve the issue. As of macOS 10.11, Wireless Xbox 360 controller support causes kernel panics. There is no 'official' Microsoft 'Mac Supported' driver at all! They are ALL unofficial, and unsupported. Just an FYI: The current Steam recommended tattiebogle driver for the Xbox 360 Controller is an 'unofficial' driver as well.
