Hi:) I’ve got a Mac Pro 5,1 (2012) that’s currently running macOS Sequoia using OpenCore Legacy Patcher that I installed with my original MacOS GPU. Everything worked perfectly fine with my previous GPU, but when I installed the AMD RX 580 I a bought a few days ago I got this weird issue with a white desktop and very slow mouse movement after booting up. I guess there is no GPU Accerlation enabled? The Dock and cursor are still visiable and functional, but the desktop background and windows are just solid white. no icons or Finder visible
I already tried running the Post-Install Root Patch in OCLP (latest version), but it fails partway through and doesn’t seem to apply correctly. with the RX 580 installed I can’t get into the boot menu (no Bootscreen with the RX 580), so I dońt know what my options are.
Has anyone else run into this and found a fix? I would appreciate any guidance or step-by-step instructions on how to properly enable GPU acceleration for the RX 580 or any other Option that would fix this issue.
