Isn’t FreeBSD a monolithic kernel? I don’t believe it provides the compartmentalisation that you talk about.
As I understand it Mach was based on BSD and was effectively a hybrid with much of the existing BSD kernel running as a single big task under the microkernel. Darwin has since updated the BSD kernel under microkernel with the current developments from FreeBSD.
