Hi, I have been following along with your youtube video. I am using Mojave 10.14 Beta (18A365a) on a ASUS Prime Z370-A motherboard with a i7 8700K and a RTX 2080 TI.
Everything is working except for the display driver (only one monitor detected, some visual artifacts), audio and sleep. I assume the graphic bugs will have to wait until drivers for the new cards are released(?)
Thanks in advance for helping out a noob, you guys are awesome for all that you do!
