How must I install it to have french version on Libre Office 4.1.3.2 on Mac ?
im having problems installing pt-BR language pack as well here. LibreOffice 4.1.3.2 on a OS Mavericks (10.9).
After downloaded the language pack file and executed, i got the window “Welcome to the install wizard of LibreOffice Language Pack …”. Choose Install. Next window says ‘choose the LibreOffice 4.1 install for which you’d like to install Language Pack’. And two options: first one if completly blank and second one is ‘not listed, choose one’. I cannot proceed with neither options 
I’m having the same problem as leonardogyn but with swedish language pack. The error message says the language pack can’t be opened because it’s coming from an unidentified developer. I’m running Mac OS X 10.9 on a new macbook pro. The language pack is 4.1.3 and LibreOffice is 4.1.3.2. I downloaded the files from the official site.
[I didn’t see the link under the word “this” in the answer below. It solved the problem for me. Thanks!]
Which version of MacOS X are you running? Are you receiving an error message? The instructions are on the lower half of this page.
