Please help me out!
I'm just starting to learn my way in Octane ... and new iMac pro will arrive within next weeks... All this CUDA and GPU thing is yet a bit of mess for me at the moment.
Do I understand your point correctly, that under newest MacOS Mojave, there is no way I can use Octane even ...

Not a dead end, but a long road ahead. Did you see our WIP from siggraph?
Yeah, looks awesome! Just tough to gauge when it'll be a stable platform. I'm not concerned about Otoy, but rather with the whole Nvidia/Apple situation and the future of "Pro" Mac hardware. It's all in a weird place right ...

It would be great to hear some ballpark timelines on when this AMD/Metal stuff will be usable.

Also, there's still no Mojave Nvidia drivers or updates regarding them.

I love using macOS for work, but it's starting to feel like a dying platform for many pro-level applications. The latest macOS Mojave doesn't support CUDA at all, but what's alarming is there doesn't appear to be anyone left that cares. I didn't even see it mentioned that it didn't have CUDA support ...
