AI Recommendation
1 suggestionWe could not find publicly available information confirming whether a native Apple Silicon build of ATOK キーワード Express exists. Just Systems, the developer, has not published clear architecture documentation in the search results available to us. Given that ATOK is an input method utility tightly integrated with macOS, contact Just Systems directly to confirm whether the current build supports Apple Silicon natively, or whether a native version is planned before macOS 28 removes Rosetta 2 support in September 2028. This is important to verify soon, as an Intel-only input method will stop functioning entirely on macOS 28 and later. If the developer confirms no native build is forthcoming, you may need to research alternative Japanese input methods for macOS with confirmed Apple Silicon support, such as the system-bundled Kotoeri or third-party options like Godan.
