This is about right, and it's changed to be more this way over time. Early versions of OS X had user lands which were more BSD-like than they are now (and optional! Used to be you had to install the "BSD Subsystem" package from your install CD if you wanted to get a proper POSIX environment). For instance, early versions used BSD init, but that was replaced with launchd.

Early versions of OS X had user lands which were more BSD-like than they are now They still have a lot of userland BSD parts. Including the very broken grep from FreeBSD (which is fixed in FreeBSD now IIRC): $ echo "abcdef" | /usr/bin/grep -o "^..." abc def (I have to use the full path to grep, because I replace macOS grep by GNU grep.)
