So far everything works except the following:-

NVIDIA® GeForce® 940MX 4GB GDDR5 (Disabled as cannot work on Mac OS)
USB 2.0 Realtek CRW SD Card Reader (Detected but not working)
Built-In Intel WLAN Card (Not supported by Mac OS)
Headphone jack not working when fully inserted. Got some audio when halfway inserted.
