I have tried to make biber to work on my machine, unsuccessfully. I have searched all over and have read all the biblatex-biber related posts, but nothing seems to do the trick. Here is a Minimal (Not working) Example:

\documentclass[12pt]{article}
\usepackage[style=numeric,backend=biber]{biblatex}
\addbibresource{../../bibliographies/example}


\begin{document}
let's cite \cite{ho1995}

\printbibliography
\end{document}

When I try to compile it as it is here, using TexShop, by doing the Latex -> Bibtex -> Latex usual path (I previoulsy modified the Preferences -> Bibtex engine from bibtex to biber) I get the following message:

dhcp109128:myfolder Laura$ biber exampleBiber
INFO - This is Biber 1.6
INFO - Logfile is 'exampleBiber.blg'
INFO - Reading 'exampleBiber.bcf'
INFO - Found 1 citekeys in bib section 0
INFO - Processing section 0
INFO - Looking for bibtex format file '../../bibliographies/example' for section 0
ERROR - Cannot find '../../bibliographies/example'!
INFO - ERRORS: 1

HOWEVER, if I change the backend from biber to bibtex and change the preferences again, I obtain a perfectly good file. I get the same issue if I try to run it in a terminal window, and again, if I run bibtex instead of biber (changing the backend each time), it works perfectly fine

Things that I have tried:

-I tried modifying the file above by adding the line % !BIB TS-program = biber at the very top, nothing happened...

-I tried updating my packages (as was suggested to me before): I am running TexLive 2013, biber 1.6, texshop 3.26 I am using bibdesk 1.6.1.

I think there might be a problem in the way bibdesk is savign the bibliography. For reference, I put the bib file at the end. Any ideas? thanks in advance

Add .bib to your bib file name in the \addbibresource command. –  Alan Munn Nov 20 '13 at 1:57
    
thank you Alan! it worked, can you formally reply so I can accept your answer? –  Laura Nov 20 '13 at 19:26

Because the \addbibresource command in biblatex can in fact open other types of resources than .bib files (most notably, URLs, and experimentally RIS, and some XML formats), the file extension .bib is required. This is quite different from the \bibliography command (which it replaced) in which the extension was implicit.

So the solution to your problem is to use:

\addbibresource{<your-bib-file>.bib}
