BSD and Darwin derivatives "I am very happy about the direction in which the Mac OS X GUI is going, although sadly many Mac users aren't interested in (or don't know about) the "lower levels" of the Macintosh Operating System. Have you ever wondered why the Terminal greets you with the words "Welcome to Darwin"? Why do BSD and Mac OS share certain bits of code? Why does Wikipedia describe Mac OS X as a graphical operating system? Today we're going to take a look at the underlying open source technology which powers your fancy Leopard OS - the hidden core set of components, named Darwin."

RE[7]: What BSD could have been

Talking compatibility with Darwin ... Rather if it was Real Open Source the same code would be inside the other BSD kernel.

The ati drivers used in OSX depend on proprietary additions which aren't available without explicit permission from Apple.

They don't , and they could if they had the same code as in Darwin ...

You are confusing two completely different things here. Any Apple-branded proprietary libraries and drivers are not part of Darwin and thus aren't distributed freely. Just think about it: Linux IS open-source and all, but you can still use proprietary nVidia drivers on it, and proprietary software on it, and Linux STILL is open-source. The same applies here: the base system (Darwin) is open-source, there just are proprietary libraries, drivers and applications running on top of it.
