Hi: "What does "kpsewhich Informe.bib" and "kpsewhich Informe2.bib" on the command line reveal?"
/Users/monicreque/Library/texmf/bibtex/bib/Informe.bib /Users/monicreque/Library/texmf/bibtex/bib/Informe2.bib These are the places where I put the bib files. "now if you run LyX from the console and try to view PDF, which messages do you get on the console?" "does the LaTeX log file contain any biblatex warning messages?" Mmm, really, when in the console I do a *open Lyx.app* it open LyX in the normal way. I can take the register of the Latex, and there are some warning errors: - Package biblatex Warning: 'babel' detected but 'csquotes' missing. Loading 'csquotes' is strongly recommended. - LaTeX Font Warning: Font shape `T1/cmss/bx/sc' undefined. using `T1/cmss/bx/n' instead on input line 61. - Class scrbook Warning: \fl...@addtolists detected! - *LaTeX Warning: There were undefined references. Package biblatex Warning: Please (re)run BibTeX on the file(s): (biblatex) Text(2)1-blx.aux (biblatex) Text(2)2-blx.aux (biblatex) and rerun LaTeX afterwards.* I think the important is the last one. Maybe it refers that the script doesn't works appropriately, but I'm not sure. The whole log file atacched.
