Some suggestions (with no guarantee, I'm not using the beamer class 
myself):

- Make a copy of beamer.cls, put it inside 
~/Library/texmf/tex/xetex/beamer, and add inside it, after:

	\DeclareOptionBeamer{pdftex}{}% Used by hyperref
	\DeclareOptionBeamer{nativepdf}{}% Used by hyperref
	\DeclareOptionBeamer{pdfmark}{}% Used by hyperref
	\DeclareOptionBeamer{dvips}{}% Used by hyperref
	\DeclareOptionBeamer{dviwindo}{}% Used by hyperref
	\DeclareOptionBeamer{dvipsone}{}% Used by hyperref
	\DeclareOptionBeamer{vtex}{}% Used by hyperref
	\DeclareOptionBeamer{ps2pdf}{}% Used by hyperref

the line

	\DeclareOptionBeamer{dvipdfm}{}

- Then call beamer with the [dvipdfm] option, to make sure the hyperref 
package is called with the proper option for XeTeX (see the version 
history notes for XeTeX 0.87).

- You should make sure the graphics and color packages are also called 
with the proper option, which is [xetex]. Some packages rely on the 
selection of this option to be determined automatically, but 
unfortunately they only know about [dvips] and [pdftex]. This may not 
be sufficient, but you may try creating inside 
~/Library/texmf/tex/xetex/config two files graphics.cfg containing 
each:

	\ExecuteOptions{xetex}

Again, that's absolutely untested.
