Yes, they are post-processed using exactly what you point at:

If anyone here would like to help: releng is eager to find a volunteer
to add hybrid HFS support to makefs, so that a stock "build.sh iso"
would be bootable (mabye with some magic args and pointers to directories
pre-populated with drivers and other apple stuff).

Of course the main point is to save releng from doing the manual step
on releases ;-)

P.S.: another option would be to modify build.sh to special-case mac* and do
the right magic using mkisofs instead of makefs (if the binary is found).
