GPU glitches after fresh install on Hackintosh with RX 580, but upgrade works fine – seeking advice.

Hey everyone,

 

I'm running an i7 10th Gen Hackintosh with an RX 580 GPU and the iGPU set to headless. I have a dual-screen setup, and my system was working flawlessly on macOS Ventura. Recently, I decided to upgrade to the latest macOS version. Instead of just doing an upgrade, I opted for a fresh install, but that’s where I ran into issues.

 

During the fresh install, I started noticing significant GPU glitches. At one point, while trying to do something graphics-intensive (not gaming, just modifying an image in the browser), I got red artifacts covering the entire screen. After troubleshooting without success, I decided to go back to Ventura and upgrade to Sequoia instead of a fresh install. Now, everything is working perfectly, even with dynamic wallpapers and my dual-screen setup.

 

I should mention that all my kexts and OpenCore itself have been upgraded to the latest version. The OpenCore config I used for both the fresh install and the upgrade is the same, so I’m puzzled as to why the fresh install resulted in glitches while the upgrade works fine.

 

My questions are:

  • What could have caused the GPU glitches on the fresh install if I was using the same OpenCore configuration? Are there any potential factors I might have missed during the fresh install process?

  • On another note, I don't have OCLP (OpenCore Legacy Patcher) installed because I mainly use LAN and not my Fenvi card for Wi-Fi/Bluetooth. Is there any advantage or reason to consider installing OCLP in this setup?

 

Appreciate any insights or advice! Thanks!
