ekwipt Posted April 15, 2020 Share Posted April 15, 2020 Hi, I'm getting black screen after boot the shutdown during installation (can install on my SSD), screen goes black for 10 mins and then shutsdown. When i start back up i belive it's going through the 2nd install part of the installation but i can't see anything. I went through a similar thing with clover when i installed 10.13.6 ages ago, i think it was fixed with VegaGraphicsFixup.kext which isnt used anymore for OC. I have tried (-v debug=0x100 slide=128 keepsyms=1 npci=0x2000 agdpmod=vit9696 alcid=1) and without agdpmod=vit9696 but still black screen, i'm using Display Port on my RX480. I've searched but can't find any solution! Whatevergreen and Lilu latest as well. working EFI without credits.zip Link to comment https://www.insanelymac.com/forum/topic/343442-x99-oc-057-catalina-10154-rx480-black-screen/ Share on other sites More sharing options...
Donw35 Posted April 19, 2020 Share Posted April 19, 2020 I never hear of agdpmod=vit9696, I am using the one below, without it black screen will happen on Radeon cards. give it a try and report back. agdpmod=pikera Link to comment https://www.insanelymac.com/forum/topic/343442-x99-oc-057-catalina-10154-rx480-black-screen/#findComment-2718226 Share on other sites More sharing options...
