For myself, this comparison of Cheetah3D and Blender is not fair as they are not intended for the same market.
but its hardware and software is just not up to the mainsteam (PC) world
For 3d works, thoughs, there is the problem of not getting nvidia cards on the mac anymore (which is a shame. Their denoiser is far better than anything amd has to offer), no threadrippers, no this nor that.
Another downside are computer games. Apple lost that customer segment a long time ago and never did enough to win it back. They will certainly not be able to with something like a mac pro.
