MacOS X is quite a bit different from Linux!  But you can install Linux
on a Mac.

We use a hardware audio mixer together with a software video mixer,
dvswitch <http://alioth.debian.org/projects/dvswitch>.  Several of us
are involved in developing dvswitch.  It currently runs on Linux but it
might be portable to MacOS X if its X server supports the Xvideo
extension.  We would probably accept a patch that adds support for MacOS
X in a clean way.

I don't use Skype but I'm aware that it encrypts/obfuscates what it does
so you probably can't feed it in directly.  However, there are various
software and hardware tools for capturing graphics from the screen or a
window, and for capturing audio output.  I don't know what's available
for MacOS X.
