As of 10.9.2 Mac OS claims to create files at PDF specification 1.4, published in 2001.

PDF 1.4 includes tagged (and thus accessible) PDF as one of many improvements over PDF 1.3, but Apple isn’t yet supporting this feature when creating PDF files.

There are two issues: creation and consumption. They are quite distinct.

Regardless of the files Apple’s software creates they could still choose to support accessibility when encountering Tagged PDF files.

At this time, however, Apple has chosen not to support accessibility features in PDF for either authors or readers. :(
