NetBSD has (or had) a macho image activator, which is the first step
in this process. But Kevin is right that most of the functionality of
MacOS isn't in the kernel, and you'd need a copy of MacOS to run it in
emulation. Plus there's a lot of Mach code that MacOS depends on that
has no simple counterparts in FreeBSD, and that would be a lot of work
to make happen. It's one of the things that's a barrier to entry for a
simple, straight forward launchd port, for example.
