Hello Bob,

First of all as far as I know some Apple stuff is hosted on linux, not 
Unix.  linux itself it open source.  If you develop starting with the 
open source code, then yes you typically have to release the code.  You 
can archive that and not ship with the product.

When you use linux and the known APIs as your base and program on top of 
that you are free to stay closed source.

How much of each Apple uses I have no idea.

These facts are to the best of my knowledge.  I've not read the licenses 
that linux has for the Apple base nor for the Apple OS.

I had a friend that could port linux to Windows and thus run the Apple 
Mac OS on a Windows machine.  Standards get you freedom like that.  I 
don't recall what version of the OS that was but it is long past.  I'm 
not an Apple user these days so I can't give many details on the 
subject.  They pay me well to use Windows so I have to use that.  I play 
with a few other things at home, mostly cars these days.

David
