The Mac Pro is intended for use as a workstation, as opposed to a typical desktop computer. Workstations are used for tasks with high computational intensity, such as video editing and rendering, 3D modeling, graphics development, etc. I expect machines like this would see use at Pixar, Sony, Weta, and so on. For example, if you watch the announcement keynote from WWDC (I think it was), they show its ability to live-render multiple 4K video streams simultaneously — where a high-end desktop would struggle with live-rendering even a single video stream of a lesser quality.
Except Pixar, Sony, Weta, etc. are all Linux houses. MacOS has very little to no presence in the top-tier CG studios for actual CG work (we have a lot of MacBooks around for Keynote and video calls and whatnot though).
Oh! I didn't realize that. Sorry, maybe my original comment wasn't clear, but I just meant that it's people in roles like those who would be using workstations such as the Mac Pro. I didn't mean to say that I had knowledge that those specific people actually used it. Apologies for any lack of clarity on my part there.
