Except when it “just doesn’t work”, like when you’re trying to develop software using OpenGL or (worse yet) OpenCL.
You rarely get to see that as user, because developers don’t like to ship software that doesn’t actually work. You never get to see the projects that are canned mid-development. You never get to see software that isn’t developed or ported in the first place, because of the bad reputation that Mac OS has accrued in this regard.
Maybe, sometimes, you get to see it as user of FOSS software like Blender, with a “let the users do the QA” attitude. But then those Mac OS bugs don’t necessarily get fixed either, because the only way to reproduce them is to buy thousands of dollars worth of “designer hardware”.
Yeah, maybe that’s the problem. People don’t actually want to do any real work on proper computers, they want to look affluent while pretending to work while sitting in a coffee shop.
