Nvidia GPUs were usable on Intel Macs, but compatibility got worse over time, and Apple stopped making a Mac Pro with regular PCIe slots in 2013. People then got hopeful about eGPUs, but they have their own caveats on top of macOS only fully working with AMD cards. So I've gotten numb to any news about Mac + GPU. The answer was always to just get a non-Apple PC with PCIe slots instead of giving yourself hoops to jump through.

The 2019 Intel Mac Pro had PCIe slots. The Apple Silicon Mac Pro still has them as well, but they’re pretty much useless.
