ATOK Sync
ATOK Sync is a companion utility for ATOK, the input method editor for Japanese text entry on macOS. ATOK Sync manages dictionary synchronisation and settings across multiple Macs when users have ATOK installed on more than one computer. It works in conjunction with the main ATOK application to keep user preferences, custom dictionary entries, and morphological data in sync via cloud storage or local network. ATOK is widely used in Japan and by Japanese-language professionals worldwide who need high-quality Kana-Kanji conversion, predictive input, and extensive dictionary customisation.
AI Recommendation
1 suggestionATOK Sync is a helper utility for ATOK 27, and like all such components, it cannot be updated independently — updating the parent ATOK application is what will bring both the main app and any bundled helpers to a current native Apple Silicon build if one is available. However, we found no search results about ATOK's native Apple Silicon support status. ATOK is developed and maintained by JustSystems, a major Japanese software company, but public English-language information about their macOS roadmap is sparse. If you rely on ATOK for Japanese text input, contact JustSystems directly (or check the official ATOK website at atok.com) to confirm whether a native Apple Silicon build is available now or planned before macOS 28 ships in September 2028. If ATOK remains Intel-only at that point, the entire IME — including ATOK Sync — will stop functioning when Rosetta 2 is removed.
