change user interface language to Spanish

I have LO installed in my Mac with only one option of language user interface. I would like Spanish as my language for the interface. What can I do?

I also have been trying to switch to spanish. I watched a video explaining I should download libra office in spanish. I did this but now i just have two english versions. it didn’t work

I found the Spanish user language package but it was not so easy and I don’t understand why its like that?

Need another language?.
