Steps causing the bug to occur:
- In System Preferences > Language & Region, set English as the first Preferred Language and German as the second Preferred Language, and set the Region to Germany.
- Launch Vuo-2.0.0-beta1.
The Vuo UI should be in English now since that's the first Preferred Language. Instead, it's in German.
Have you found a workaround?:
in System Preferences > Language & Region > Preferred Languages, remove German. (But you can keep Region set to Germany.)
