That's true. It's cryptic.

1) LyX is missing the "convert" utility. 
I think,it's normally part of MacTeX and can be found in directory 
/usr/local/bin.
Either LyX cannot access it or the directory is not part of the PATH setting.
You can find it in the Preferences pane (use Command-, to open it).
Check the PATH-Prefix contents - /usr/local/bin should be there.

2) TeX cannot find article.cls and other class files.
These are part of MacTeX and can be found in directory /usr/local/texlive.
For me it's .../2012/texmf-dist/tex/latex/base/article.cls

Try to reconfigure LyX. But if you never used LyX before it might be pointless.
