That depends a lot on weather the freeBSD compatiblity layer is kernel or user space as MacOS contrary to common space does not use an freeBSD derived kernel but one derived from the CMU mach64 project, and yes i know jobs said otherwise but he was never a trustworthy source for anything. I think macos actually uses an different binary executable format then the elf64 one shared between linux and freebsd, so the kind of binary level compatiblity that linux and freebsd share might not be shared between macos and freebsd.
