It means you have to shutdown the system yourself, because
shutdown -k won't do it.

The -k option just logs out any users and prevents further
logins. From the manual:

     -k      Kick everybody off.  The -k option does not actually halt the
             system, but leaves the system multi-user with logins disabled
             (for all but super-user).

Maybe you're searching for something that really shuts down
the system? Check those options:

	-h	-> shutdown and halt system (don't power off)
		   related command: halt

	-p	-> shutdown and power off system
		   related command: poweroff

	-r	-> shutdown and reboot system
		   related command: reboot

See "man shutdown" for details. On macOS, you'll probably
have local access to the manuals. :-)

FreeBSD's userland is in fact part of the macOS software.
But it uses a different kernel (Darwin).

See the BSD family tree (and Mac OS X / macOS in relation to
FreeBSD):
