MacPro 5.1, games won't start after Mojave upgrade.

[pgilmore7]

After installing Mojave on my MP5.1 my games won't start, I get an error message stating, Error: Could not init 3D system. Shader Model 3.0 required. Anyone have this issue? Im running a NVIDIA GeForce GTX 580 GPU, everything else seems to be running fine. Any help would be appreciated.

GTX 580 is not one of the NVIDIA GPUs that have Mojave support. It's a Fermi GPU, Apple native NVIDIA drivers are made to support Kepler NVIDIA GPUs like GTX 680/780, GTX TITAN, TITAN BLACK, Quadro K5000.

With a GTX 580, the last macOS version that fully support it is High Sierra.

Thanks for the info, I was afraid of something like that. I guess its time for a GPU upgrade.

Yeah, if you love 580, it's time to go for a AMD RX580
