App Language Chooser
App Language Chooser is a macOS utility that lets developers and multilingual users launch applications in a specific language without changing the system-wide language preferences. It provides a simple way to open any installed app in any of its supported language variants, useful for testing internationalization, supporting users in different locales, or working in a non-native language for specific tasks. The app is available on the Mac App Store.

1 suggestionApp Language Chooser is a 32-bit Intel application built in 2011 (version 1.0) with no native Apple Silicon build. The app will stop working entirely when Apple removes Rosetta 2 in macOS 28 (September 2028). Given that the app has not been updated in over a decade and there is no indication of ongoing development, it is unlikely a native build will be released. If you rely on App Language Chooser for regular language-switching workflows, you should plan to migrate to an alternative before September 2028. For basic app-language testing, consider using the Terminal to launch apps with specific language preferences via the `defaults` command or LaunchServices APIs—many developers handle this through scripts. Alternatively, search the Mac App Store for newer language-switching utilities or ask in developer communities if anyone has built a native replacement for this functionality.
