This is a really weird response. 1. Nowhere did I mention Blender, although yes, this is a primary gripe 2. Even if I had, where does the inference that Blender somehow drove this come from? 3. Why leave out Metal2 and AMD frome the discussion?
Sorry for the late reply. I assumed that your comment was about Blender given that you've commented on a post about it. I also assumed that the comment was directed at Blender because there have been plenty similar comments/questions w.r.t. CUDA support on Blender's Stack Exchange in the past. Since you were addressing CUDA in particular, that's what I did in my reply as well.
No worries, CUDA (non)support on Mac is clearly directly created by Apple
