I cannot speak for OP, but software is the reason for me. I can not run Solidworks on MacOS without bootcamp or other tricks, for example. Photogrammetry apps? GIS apps? CNC CAM apps? I mean, compare the Mac[1] compatible apps to the catalog of Apps Autodesk has.
The fact of the matter is GPU support on MacOS is just not there in the same way it is with windows. It is really hard to justify the price of Apple when you compare directly to Windows offerings spec for spec. When you compare the sheer volume of software available for Windows as compared to MacOS, especially if you need a discrete GPU there are really no comparisons.
I'm always surprised when I see discussions about somebody dumping one operating system for another. Isn't your operating system choice dictated by the applications you want to run?
