PDF is an integral part of Quartz, the OS X display service (so of
*course* it's included in every installation). In this context,
"native" means the entire display system is built upon it, as this
old article from Ars Technica describes:

I hope no one thinks that's a good idea. If you do, I suggest hearing
Julia Wolf's PDF talk at the 27th Chaos Communication Congress in
December 2010 in Berlin (youtube vid _l6eaiBIQH8k).

On Linux and Windows, PDF is *much* more of an afterthought. I
believe that is the point.

Sandboxing PDF (or not having PDF) is a forward-thinking good idea.
Integrating it into the OS is a rock-stupid idea. If not integrating
PDF into the OS was really an "afterthought", then they unwittingly
took the street-wise path.
