Hi, thank you for the response: On Mac, BibLaTeX should go in ~/Library/texmf/.... (Make sure you put the biblatex.bst file in the bibtex/bst/ directory, and everything else in the tex/latex/ directory
Ok, everything was where you say. Biblatex.module was in the ~/application support/Lyx�C1.6/Layouts All the files of the latex directory of the packet I've downloaded was in the ~/tex/latex/biblatex directory biblatex.bst was in ~/Library/Texmf/Bibtex/bst At this point, in the Readme of Biblatex say "[…] and the file in the 'bibtex' directory [it refers to biblatex.bst] to <TEXMFLOCAL>/bibtex/bst/biblatex/" I just create this directory and put the biblatex.bst there. Now I hace two biblatex.bst, one in ~/Library/Texmf/Bibtex/bst and another in ~/Library/Texmf/Bibtex/bst/biblatex "Make sure you do texhash (not "rehash" as you say above); I'm sorry!. I did sudo texhash, but I wrote rehash in the post. Was an error while writing… I've done texhash and reconfigure, but the module doesnt appears in the D ocument→Settings→Modules... It doesn't work because I have two biblatex.module files or two biblatex.bst? Now I'm making the references manually ―make a footnote and write the whole reference. Copy it into the biliography append, and its OK. And I can put Ibíd or Op. cit.!― Works very fine and whithout downloading anything!. Really, I need to make the references automatically, I'm typing a lot of them, but i don't know what happens with my Lyx. Regards Antonio
