Hello! A few months ago, I successfully installed MacOS 12.2.1 on my computer, but after first reboot system no longer boots. After the logo, all I see is a black screen and green lines. I couldn’t fix that. After a while I tried to configure OpenCore again, but the problem reappeared. What am I doing wrong?

My PC specs:
  • CPU - FX8350
  • GPU - ARMOR MSI RX570 8GB
  • Motherboard - GIGABYTE GA-970A-DS3P rev2
  • HDD - Seagate Barracuda 720

BIOS:
  • CSM - disabled
  • XHCI - enabled
  • EHCI - enabled
  • IOMMU - enabled
  • Sata type - AHCI

Okay one more thing to try. I've created a new EFI based upon my current B550 which works with Monterey 12.4.
I've already adjusted for your cores. Give it a try (but you'll need to add your UUID, ROM and serials back in).
My PC just reboots on this EFI after starting loading kernel (kernel panic?)

Update: I flashed the VBIOS on my GPU, but this did not help
See if checking Vector Acceleration helps under the UEFI > Quirks section.
