French translation on mac

Hello, my interface ardour 5.6 is in English. How to put it in French?

thank you

Set your system language to French. If that doesn’t work … you are likely suffering from a problem that seems to only show up on recent versions of OS X (MacOS). I suspect that Apple has changed their underlying internationalization system, and that Ardour no longer picks this up.

Yes I think so.
Therefore no solution ?
