I think I've figured out what has been going wrong with the LyX/Mac
installer, and I've created a new version (partly in preparation for
the upcoming 1.4.0). If you've been having troubles upgrading from
lyx-1.3.5 or earlier on the mac, please try this installer to see if
it works for you.
To test it, do the following:
1. Make sure you have an existing ~/.lyx folder and that there is a
preferences file in there. (If you don't have the folder, simply
launch LyX-1.3.5, and a new one will be created -- though without the
preferences file. If you're lacking the preferences file, simply
launch LyX-1.3.5, select LyX > Preferences, change any field, and
save preferences.)
2. Run the installer. Generate a report (at the end), and copy the
resulting text into an e-mail message to me.
3. Launch LyX-1.3.7, and run Edit > Reconfigure. Quit and relaunch
LyX-1.3.7.
4. Open a document (in LyX-1.3.7), and try to typeset it in various
ways (pdflatex, dvipdfm, ps2pdf, etc.).
Report any problems to me.

Thanks.
