MacOSX is based on freeBSD, if recall correctly.

It is

Based in BSD... freeBSD is a distribution.

And AMD have drives to Mac OS X... I don't why people thinks there are no driver for freeBSD... BTW the driver for a console is way different with direct access to GPU without concurrence with OS.

But if the BSD is free, shouldnt MacOS be free too (similar to android and linux)?  The last time I checked apple website; you needed to pay for the OS update.

The base of MacOSX is Darwin, an open-source UNIX developed by Apple and based long time ago on BSD-code. As all Unices it has many programs that work together. As far as I know XNU is the kernel. You can download the sources at Apple and compile it yourself to a working Unix without the graphical UI that Apple developed on top of it, not based on BSD and not open-sourced.
