As of the latest release (11.1) Tbx seems to consider the computer’s system language. Mine is German, but I’d like to stay with the English localization of Tinderbox. How can I switch Tinderbox from German back to English?
Open System Settings, and go to the Language & Region panel.
At the bottom right, you’ll find a section in which you can specify exceptions. So you can specify that Tinderbox use English even if the default is German.
