I had a devil of a time finding out how to make pdfsyc work. I finally
found the answer in the developer's mail list. I suggest adding the
following the the mac section of the wiki near where DVI search is
written. (No password so I couldn't do it myself.) http://wiki.lyx.org/Mac/Mac#toc7

PS Is there a way to click in LyX and go to that spot in the pdf.
(Taken from the developer's mail list).
In PDFView's preferences, use a custom preset for PDFSync support,
with the following entries:
/Applications/LyX.app/Contents/MacOS/lyxeditor
"%file" %line
Also, make sure that the .lyxpipe.in and .lyxpipe.out files do not
exist when LyX is not running. (They are normally deleted when LyX
quits, but if LyX crashes, they remain and prevent LyX from
communicating with PDFView.) Their location can be found in LyX >
Preferences > Paths.
In LyX > Preferences > File formats > PDF (pdflatex), enter "open -a
PDFView.app $$i" (without quotes) in the viewer setting. *Then* you
need to click the Modify button, and then Save.
Make sure that you include
\usepackage{pdfsync}
in your preamble.
Then <Cmd>-click in PDFView should take you to the relevant place in
the LyX document.
