NetBSD started working on one, and had it at a state where it could run the Darwin version of XFree86 (which should give you some idea of how old it was), but it couldn’t run the Mac Window Server and I don’t think it’s maintained. It’s not very interesting, because you need all of the frameworks and programs from OS X for it to be useful, and the license prohibits using them in such a way (and even if you did get it to work, you wouldn’t be able to run Mac apps at the same time as X apps without running XQuartz, and at that point you may as well just run macOS).

There is a more recent project called Darling ( that tries to run Mac apps on Linux using a custom Mach-O loader, bits of GNUstep, and some of their own stuff.  No one has ever tried using it on FreeBSD, to the best of my knowledge.  It’s GPLv3, so I’m not motivated to contribute to it (though it does incorporate some of my code in various places).
