> I would posit that Apple is always going to keep macOS working on some workstation-class hardware, just because that kind of machine is what Apple's software engineers will be using internally, and they need to write macOS software using macOS. I hope I'm not out of line here, but this is not what a "workstation" is. "Workstation" actually has a specific meaning in the realm of enterprise computing solutions, and developers do not (generally) use workstations. A workstation is something that, say, the people at Pixar use, or Industrial Light and Magic. It's an incredibly powerful machine that can handle the most intensive of tasks. Software development is generally not such a task, unless you're frequently re-compiling LLVM from source or something. (And even then, it's a world of difference.) Apple's software developers, like most software developers who use Apple machines, use MacBook Pros (for the most part). Sometimes Mac Minis if they need multiple test machines, and I'm sure there are some who also have Mac Pros. But overwhelmingly, development is done on laptops that they dock while at work and take home with them after. (This was my experience when I interned there, anyway.)
