10.15.1 | 8GB Sapphire RX 5700 XT Nitro+ black screen

[lkshrk]

Hey there,

i bought a new RX 5700 XT and upgraded my Hackintosh to Catalina 10.15.1
The update went well, but after replacing my old card the system starts booting but stops at a black screen.

I already tried using Lilu 1.3.9 and WhateverGreen 1.3.4

My System definition is currently on iMac 14,2.

Any ideas how to solve this issue?

Thanks a lot in advance

Did you try disabling the IGPU in bios?
