That is fair but in my experience most devs are targeting linux servers not BSD(or any other flavour) which is helped by OSX. If OSX was linux derived it would suit them just as well.

edit: I suppose I should also note the vast majority of people developing on mac books (in my experience anyway) are actually targeting chrome.

There is no reality that macOS could be based on Linux.

Turns out, an operating system is more than just a kernel with some userspace crap tacked on top, unlike what Linux distros tend to be.

Heterogeneity is the feature. The Linux ecosystem is better off for it (systemd, Wayland, dconf, epoll, inotify are all based on ideas that were in OS X first) and not being beholden to Linux is a competitive advantage for Apple everyone wins.

Point taken. Most developers probably make do with Linux containers rather than MacOS VMs.
