Same problem here. I have the same GPUs. I actually booted using my intel GPU and I got homescreen and checked software version and it’s updated. So the problem is definitely the RX580. I’ve tried all the suggestions here. I may take the card out, boot using input, then put the RX580 back in to see if it installs it. That’s my last option.I have Mohave and Catalina on 2 separate disks. They were working perfectly until I upgraded to 10.15.1 on the Catalina disk. I never had to use WEG, just Lilu, and that's still what is working on the Mohave disk, what I'm using right now. I have tried every combination of, WEG 1.3.4, Lilu 1.3.8, agdpmod=pikera boot arg., I get nothing but black screens. 2 monitors. Tried using just 1 monitor in all ports, and nothing works. I know 10.15.1 is working because I have Remote Desktop on another computer and can connect with no problem. I can see my RX580 in system report but no displays are attached. Can't figure out what's going on, any help would be much appreciated.
I pulled the RX580, booted on intel igpu and this is what I found:
As you can see, the update had finished.
I then shutdown, reinstalled the RX580, rebooted, and still black screen.
This is crazy. I bought the 580 because it was native and Apple friendly.
I have tried every suggestion here including Latest WEG,Lilu,AppleALC, boot args, you name it.
If you guys can offer any other suggestions I will try them.
Other than that, I'll forego the update on this computer.
Ironically, My NUC8i5BEH updated quickly and accurately. Go figure.
