Where was answered? My Catalina worked perfect before install update. My WhateverGreen is updated.
What should I do....? It doesn't work.

Keyboard works and sound too. But screen is black.

I've installed MacOS 10.15.1 upgrade.

Probably after hit password and enter, system works... but still nothing on screen...

When I turn off CMS in the BIOS, I get the message "the vga card is not supported by uefi driver". The CMS is enabled automatically... Any solution?

I messed this one myself. What would be an easier way to intall WhateverGreen.kext within Clover screen? Because all I got past Clover is blank screen. I tried `-x -v -f` boot args, `nv_disable=1` (even though mine is RX580), none seem to work.

Update:
I can still use my blank screen computer via screen sharing service, in my case, Chrome Remote Desktop. Then I installed WhateverGreen.kext, Lilu.kext, and AppleALC using Hackintool (KextBeast didn't work for me). The issue has been resolved.
