Explain why Mac is the fastest growing PC platform of the year, the last 5 years, the last 10 years and the last 20 years? Explain why Mac dominates high end PC sales with an average sales price of nearly 3x Windows PCs?
Apparently none of these apps have a very large audience and apparently Apple has targeted the largest creative professional audiences very well.
Are you insane?
Maya is the industry standard 3D modelling, Rigging & Animation software for major CG studios whether it's VFX or Game Development.
Didn't bring 3DS MAX as it's not available on Mac.
Houdini is the industry standard for procedural modeling & FX simulation. It's the go to software for FX simulation in Hollywood as well as some game studios as well.
Same with Nuke & Mari, both of them are industry standard Compositing & Procedural Texturing/Hand painted Texturing software.
Vray & Arnold are industry standard Physical based render engines.
Unreal is the Industry standard tool for Real time artists as well as Virtual production, Arch-Vis, & AAA game development.
Unity is another major game engine used widely in everywhere from Mobile games to Indie games to small scale AA games. They have also acquired WETA & Ziva another two proprietary Hollywood exclusive FX tools. Another market where Apple barely exist.
I don't know what is your definition of creative software if these software don't fulfil your requirement.
And I didn't even mention many of the other software used in the production pipeline which are used for niche cases like Gaya, Yeti, Terragen, Character Creator, World Creator etc.
These all are general software, mainstream used in every industry standard pipeline.
