I have i7-10700K and MSI RX 580 OC 8GB. The only difference from
@Stork is the CPU.
You guys did great but I need your help.
I used the EFI folder a few page previous. I get installation page and installed the Catalina. But, after installation, I just have black screen on both onboard and RX 580.
Second problem. When I select the first graphics card as PCIe, it does not boot from RX 580 but the internal one. Then, after a few seconds, the internal graphics has no signal, then the RX 580 gives output. When I restar into the BIOS, it turned to internal GPU again and again.
Guys, can anyone share a working EFI folder of OpenCore please? (0.6.x please.)
