The extra-painful part about this whole situation is that it's apparently only due to Apple blocking NVIDIA from signing and publishing their drivers. (for whatever bizarre reason they may have to do that)
I know it stinks for the people who are acustom to Nvidia's workflow, but it is quite hard to feel bad for Nvidia. A bigger fish is doing to them what they do to smaller players.
I think there’s more to the story than Nvidia is letting on. It wouldn’t surprise me a single bit if Apple is blocking Nvidia due to something like QA issues — Nvidia’s web drivers are notoriously buggy under macOS and Nvidia seems completely unrepentant about it. Pair this with Nvidia’s unwillingness to share source and collaborate with other companies on development and you’ve got problems.
I currently run an EVGA 980Ti Classified in my hackintosh. It’s great hardware, but with the frequency of glitches that the drivers bring I’m increasingly inclined to sell it and replace it with an AMD card.
