How do I get Latin as my system preference language on Mac?

I´m currently learning Latin and would like to have my user interface and system preferences in Latin. So I just wonder if there are any apps or plugins or something like that I could try

There's no way to do what you want on a Mac (or Windows or Linux as far as I know). MacOS does have Latin on its list of languages, and you could make it the Preferred Language, but that just means that if their were an app with a latin gui, that is what would display. I have never heard of such an app, however.

Probably not, but you could try Googling for it.

What version of OS X are you running?
