Lyx was working fine for me with OS X 10.8 (I don't think I tried it
with OS X 10.9), but I have major problems since installing OS X 10.10
beta on my seconadary computer. The problems are identical with Lyx
2.0.7.1 and Lyx 2.1.1.
When opening Lyx documents, I get messages like:
"The selected document class Article (Standard Class) requires
external files that are not available. The document class can still be
used, but the document cannot be compiled until the following
prerequisites are installed: article.cls
See section 3.1.2.2 (Class Availability) of the User's Guide for more
information."
If I select Tools->TeX Information, no classes are shown. Help->
LaTeX Configuration finds no fonts, classes, paper layout packages, etc.
I have a working LaTeX, with the various classes, etc installed at
/sw/share/texmf-dist. LaTeX itself is found at /sw/bin/latex.
/sw/bin is in the PATH prefix listed in the Lyx preferences.
I've run texhash, and Tools->Reconfigure, and then restarted Lyx, but
that makes no difference.
I can't help with the details, but this sounds like a python problem,
which we've seen before, on various platforms. LyX needs to run python
2.x, but the default version on some platforms is 3.x.
Someone on OSX will be able to help fix this. For now, you might try
running LyX from a terminal and seeing what error messages you get when
you reconfigure.
