Darwin was based on NeXT, which as far as I can recall, wasn't open source before Apple opened it. While a number of the userland tools were (and are) open source, I don't recall the kernel being open.

There's also things like the streaming server which as far as I can tell was strictly an Apple project. I think libdispatch was also strictly an Apple project.

I mean it's based on Mach and FreeBSD both of which are open source.

    True they're open source. One of the lead developers on Mach was Avie Tevanian who went to work at NeXT after he left CMU. It was later that components from FreeBSD were included.
