Any further speculation about NVIDIA's future compatibility on macOS is entirely useless. Wait for the 7,1 and maybe there will be answers or further clarity for those holding out hope. NVIDIA continues to update current/existing Web Drivers for all OS versions through High Sierra. If/when/until drivers become available for Mojave or future OS versions, NVIDIA GPUs on Mac are on life support.
No GPUs past 10XX series/Pascal work with High Sierra (and good luck finding them as brand new retail these days). Volta was briefly supported and pulled. CUDA on Mac is nearly dead. No eGPU support for NVIDIA GPUs. Holding onto old OS versions for something like this is not sustainable long-term. Move to AMD and Apple's recommended GPUs on macOS or move on. If you want/need to be using NVIDIA GPUs on macOS, stay with High Sierra and Pascal or older. If want/need to use newer, switch to Windows or AMD.
Today's release of RED CINE-X Pro with updates for Windows ONLY with NVIDIA GPUs further proves the issue with NVIDIA (and CUDA) on Mac going forward. Software that relies on CUDA is basically dead on Mac going forward. They need to embrace Metal on macOS or leave Apple/macOS entirely.
