It's even more common with windows-only software.
Every single tool in the console homebrew space, I swear. And it's not like the code isn't portable, it's usually just some command-line / batch thing; but they just don't bother to compile it for anything other than Windows; and then they don't release it as OSS for you to do so, either. The number of things I've had to run under WINE...
Not that it is not annoying, it is, but that's pretty common with Mac-only software in my experience.
