I use macOS in a Windows environment out of my own pocket (the company supplies Windows computers to its employees). I do this because of two primary reasons: One, my own personal computer used at work is not subject to the same management structure that the other office computers are subject to. This means all of my access is remote and no files reside on my computer - but it's a small price to pay for having newer technology. The other reason is that my entire technical life lives inside the Apple Ecosystem. I bought it years ago and am now too deep to even contemplate moving away. As such, my computer at work connects to my iPad and iPhone so I can use the functions of taking pictures with my phone from my computer as well as using my iPad as another monitor when needed.
