Actually, it seems rather that OS X and FreeBSD have a common ancestor. They're close, but

the code for this doesn't compiler because of missing definitions like struct cmsgcred .
Curiously that struct is defined in /usr/include/sys/socket.h, but in a #ifndef __APPLE__ block.

OS X *does* have a version of ucred, so for a second I thought it might be possible to adapt the LINUX_UCRED code.
However, sys/ucred.h is rather unambiguous about struct ucred:

 * Note that this structure should not be used outside the kernel, nor should
 * it or copies of it be exported outside.
