bcntower Posted May 5, 2020 Share Posted May 5, 2020 Hi to everyone!I've installed MacOS in several computers with no problem, but I'm stuck with this one.It's an legacy computer:Mobo: Gigabyte GA-EX58-UD5CPU: iCore 7 950Power Supply: Corsair CS750M3 SATA HHD (1 SSD)GPU: Sapphire Pulse Radeon RX580 (8GB) through a HDMI cableThis computer had a Radeon HD 5770 and was running Lion fine, but I wanted to upgrade it. So I installed Mojave (Catalina was impossible because I was not able to get the SSD recognised) and everything was OK but the screen resolution (just 1024x578). I read that this was because the GPU was not supported by Catalina.After reading some posts, I decided to buy the Sapphire RX580. With the config.plist I used, after Apple logo the GPU stopped working (fans stopped). So I did some things:- I modified the config.plist (is the 'config rx850.plist' in the attached EFI folder).- I updated both Lilu.kext and Whatevergreen.kext to the last version (1.4.3)- I updated Clover to 5114.With all of this, the only thing I can get is a black screen after Apple logo (but the GPU fans are running). It happens if I run the Mojave installed and I try to run the installer.Any help is appreciated. I've attached the Clover in the EFI folder (just with Lilu and WhateverGreen in Kexts/Other folder).Thanks in advance! CLOVER.zip Quote Link to comment Share on other sites More sharing options...

bcntower Posted May 17, 2020 Author Share Posted May 17, 2020 (edited) Thanks @Â ACPI Eater. The solution to that was connecting the RX580 through a dp port. I managed to install Catalina with no problems and running smooth with a iMac14,2 sysdef. Thanks again!!! How can I change the thread status to 'Solved'?
