​

Finally!

Finally had success with my first Ryzentosh!

SPECS:

AsRock B450 itx/ac Fatal1ty Gaming

AMD Ryzen 7 3700X

AMD RX 5700 XT

16GB DDR4 (running stable at 3600mhz)

Separate disks for Windows 10 and macOS.

​

What isn't working:

- WiFi (using HoRNDIS .kext, worked during install as well)

- Haven't attempted iMessage (but possibly working)

​

I got my USB (and Bluetooth) working by compiling and using this custom SSDT:
