Earlier quoted context omitted.
I think the macOS monoculture is going to go away in the next few years because on one side macOS is becoming more and more developer hostile with each release and on the other side WSL (and WSL2) is improving the Windows developer experience a lot. I use Windows as my daily driver OS now for both native/web/mobile/devops work and I expect to see more and more developers making that same switch in the coming years.
For folks considering the switch, I highly recommend considering linux as well. I've used both macOS and ubuntu as a development environment, and bug wise they are on par, but linux really excels at having a true "native" development environment. Docker without a weird VM, true bash, etc.
Also, Mac is a certified UNIX environment, it is native.
