I would love to see something like a modern day high-end Apple-ified version of a SGI O2 (Cube/xMac) or Octane (xMac/Mac Pro) type workstation, and publicized proof of Disney/Pixar/ILM/some tier 1 animation/effects house(s) "making the transition"... But right now most of those folks are rocking Xeons & Quadros while running Linux, with highly specialized & proprietary softwares... Apple needs to make (buy) some 3d software & renderer (at least license a renderer?) & roll it into a Digital Content Creation suite, with Final Cut Pro X & Logic Pro X & revive Phenomenon (Shake), stuff like that...
I think that train left the station a very long time ago. After completely killing off shake and that infamous Final Cut update when Apple decided that EDLs aren't needed anymore for professional film editing and negative cutting, pretty much anyone in high end post-production would start looking for alternative software if Apple would acquire the likes of Autodesk or their smaller competitors.
In the company I worked for at the time, we basically decided the day after the Trash Can was revealed that we won't buy any of those in the future and ordered a couple of maxed out cheese graters from our retailer to bridge the gap to something better. We later got some Trash Cans with turnkey systems like Resolve Studio, but that was basically torture for the admins and the operators. That something better ended up being a HP Z-series workstation running Windows 7 or Red Hat Linux in most cases like in so many other companies in the industry.
I'm not even mentioning that the talented developers would most likely run as fast as they could as well, if they get bought by Apple. They already do if they work for companies bought by Autodesk. If it wasn't for ProRes nobody at the high end would care much about Apple except the audio guys, but I think some of them still haven't found replacements for their old G4s running ProTools. ?

I don't know if you ever worked for anything professional cinema, broadcast TV or post-production related, but if you did, you probably would have noticed at the Mac Pro presentation how little Apple and it's marketing department actually understands professional needs in this sector. Especially the comparisons between a reference display and the Pro Display XDR were absolutely cringeworthy. That made those silly little joke comparisons between iPad Pros and $500 cheapo laptops by Phil Schiller look like scientifically researched market studies. Too be completely honest, the whole Mac Pro, P3 color gamut stuff and even the current Mac Mini lineup feels like Pixar, Dreamworks and others who actually still heavily use macOS in many areas, sent some angry letters with a wishlist to Tim Cook who forwarded them to R&D and a note to make it happen.

Btw, if you are interested why high end 3D CGI is so heavily invested into Linux and OpenGL, look at the histories of old Silicon Graphics Inc., Nvidia and Autodesk.
There is basically no way Apple could capture the interest of companies doing large scale 3D CGI for digital cinema today. It would require listening to very specific hardware and software demands, acting on them and embracing open* systems, while at the same time shaving the cost down for both to the absolute minimums.
Probably the biggest hurdle would be that Tim Cook had to work with Leatherjacket, who actually seems to understand these very specific customers.
Almost all film studios or post-production facilities use the best tool for the job regardless of hardware platform, which leaves Apple typically in the audio departments, partially with video editing, 2D compositing, and color-grading within the highly optimized production pipelines.
