I am running a fresh install of 10.15.2 with a compatible EFI (I have a similar system with a 5700xt I used off of. I built this second machine down to the same parts aside from CPU / GPU. I have the latest drivers / kexts installed (Writing this from my working Hackintosh) and removed the Pikera boot flag I needed with my 5700xt.
The installer boots and installs in full resolution without a single issue. Upon the final reboot where it gets to the welcome screen, I have a black screen persisting after the apple loading bar is complete.
AsRock B450 Pro 4
Asus RX 470
NVME Boot Drive
Again, this is an identical system aside from the CPU (which shouldn't make a difference) and the graphics chip. HOWEVER, I did have the RX 470 running in the other Hackintosh before I upgraded to Navi - now I can't get it to boot without the black screen.
Here is my EFI:

Can anyone help me out? TIA!
