I believe the mechanism is slightly different (though the conclusion
is similar): if I remember right, pdfsync.sty actually writes an
auxiliary file with the sync information. But in order to do this, it
needs to know where it is on the page while executing a \write
command; and standard TeX doesn't know this. So I assume it is using
a pdfTeX extension, and therefore won't work with XeTeX.
In theory, a technically-inclined user could create a XeTeX
equivalent, by modifying pdfsync.sty to write \special commands with
the sync data, and modifying xdv2pdf_mergemarks (a Perl script that
post-processes the output) to read this and create the pdfsync file
that TeXShop expects. But I'm not going to attempt this myself, as
the little time I can spend on XeTeX-related development is going
into other features....

Not always closely, though I do try to notice if XeTeX issues come
up. It's always nice if someone answers them for me, though! :)

The built-in "Search" sync method has worked reasonably well for me
(it can be a bit fussy, depending on the nature of your text). I
don't use pdfsync.sty (see above).
