Adobe Reader and Acrobat use their own PDF rendering engine, which is
different from the built-in OS X rendering engine used by other
applications (Preview, TeXShop, ...). What you see is a manifestation
I tried with your test file and the two XDVI-to-PDF drivers XeLaTeX
can use: the default (for now) xdv2pdf and the alternative (for now)
xdvipdfmx. Both embed the fonts (Cochin and Zapfino) properly, thus
there's no problem there. It really just comes down to how Adobe
applications render PDF, namely to how they use font hints to draw on
Remember that Adobe applications for the Mac are essentially second-
thought hasty Mac ports of Windows applications, though that probably
isn't the only cause for the problem, given you experience the same
rendering issues with Acrobat on Windows.
Here are screenshots on what I see with Acrobat and Preview (on
Acrobat output isn't that bad: the vertical alignment of characters in
the "Introduction" title is admittedly not as nice as that with
Preview, but that's probably just the result of the rendering choices
hardwired within Acrobat.
