It's not clear to me that you are going to obtain anything different by asking
your questions here. :-)

You ought to ask Ernie Prabhakar, Wilfredo Sanchez, Jordan Hubbard, or someone
like them at Apple. Asking about what Apple has done for FreeBSD, or vice
versa, is like studying one tree out of a forest. People at Apple have make
significant contributions on for the Apache 2, Java, Samba, GCC, and such, as
well as to the BSD projects.

The Darwin kernel, Mach, is not related to FreeBSD in any way.
Apple mostly started with NetBSD improvements to their NEXTSTEP-derived
userland based on an old BSD 4.3 version, and since have adopted many changes
from FreeBSD as well. Stuff like Unix CLI programs, various standard C
library fixes and updates, IPFW, KAME's IPv6 stack, things like that.

I know at least one FreeBSD committer who is working at Apple, so I suppose
that providing jobs counts as money...? I don't know about equipment. Yes,
to source code.
Apple recently released a bunch of changes and fixes to the MS-DOS filesystem
compatibility kernel module, which someone here was looking over. I'd
imagine you could find other examples if you looked, to answer the second
question.

Others have responded to this with URLs that are more useful, but "lots,
except for GUI programs", yes, and yes would be my answers.
