As a developer we must test our applications in different languages. There are some tools available to do this. If your app is working with numbers and currencies you want also have the default number and currency formats for the selected language, not only the GUI. You can change the language and the locale settings (number and currency) in the Mac OS X settings, but these are to many steps. You can use the command line in a terminal to start an app in a different language, or you can use my tool "Açana App Language".
1. Command line in terminal:
Language in English and Locale settings, currency in British £
/Applications/<YourApplication>.app/Contents/MacOS/<YourApplication>' -AppleLanguages "(en-US)" -AppleLocale "en-UK"&
Language in German and Locale settings, currency in €
/Applications/<YourApplication>.app/Contents/MacOS/<YourApplication>' -AppleLanguages "(de-DE" -AppleLocale "de-DE"&
2. Use "Açana App Language"
Start "Açana App Language", drop your app, select a language and a region and double click on the app icon
"Açana App Language" is only for Mac OS X and it is free to use for all people (developer and customer). You can download it here:
