This is even down to certain firmware versions causing black screens. Similar generations of ATI/AMD cards are mostly problematic and it is quite hard to pick models that work.

What is kind of amusing, is the fact that older Kepler cards are very well supported by Mojave/Catalina (& potentially Big Sur). The latter should use discrete graphics cards and avoid the sluggish Intel iGPUs.Ī general comment re Apple/AMD/NVIDIA. This applies to officially unsupported Macs like classic Mac Pros as well as Hackintoshes up to 10gen Intel CPUs. A must however is to keep the original Mac card handy but not plugged in. Reliance on on-board firmware code severly limits your options and is expensive. Use OpenCore as boot manager, that is the cleverst way to get a boot screen. I have reviewed it and added some comments.

I had compiled a list of NVIDIA Metal cards.
