Dear all, Unfortunately almost all document classes are gone in Lyx including natbib. In the past, I installed some additional classes e.g. Springer SV global V3, which are gone in LYX too even the files are still available in the folder (e.g. usr/local/texlive/texmf-local/tex/latex/local). Lyx version 2.12 and MacTex is uptodate including all updates. MacOsX is Yosemite. I noticed that „Reconfigure“ is way quicker after this bug came. „Texhash“ and "$ sudo -H mktexlsr“ did not help either.
Any idea? Thank you very much in advance, Sebastian
