MP 1,1-5,1 Adding a metal GPU to a Mac pro 5,1 system boot crash AMD 580

[thomasonlineva]

I installed a AMD 580 mac card on my 5,1 MacPro. It crashes during boot. I tried with several operating systems. The only one that boots is Mojave. Boot fails with Monterey, Big Sur, Ventura, all were working with an invida card.

i can not run open core 1.3 patcher in Mojave, it errors on startup.

i reset the epram and the smc.
open core 1.3 is installed on Big Sur, Monterey, and Ventura.

i could not find any threads on upgrading gpu issues

thanks

Have you tried safe booting into the other OS?

Hold the shift key during selecting the OS in the OpenCore boot menu.

Then revert boot patches, reboot and reapply boot patches.

Thank you, I have tried safe booting, both shift and shift with enter, but is still crasher during boot
.

How do I revert the open core patches? Reinstall earlier versions of open core?

I can reinstall the nvidia card, and make changes?

yes, you may try that, but just revert the root patches with the the Patcher App 1.3.0
