[Bug] macOS app remains in English after selecting Chinese as the UI language
Summary
After updating to the latest Codex macOS app, selecting Chinese (中文) under Settings → General → Language does not localize the app UI. The setting appears to be saved, but many major UI surfaces remain in English.
Steps to reproduce
- Open Codex on macOS.
- Go to Settings → General.
- Set Language to 中文.
- Return to the main window and open the sidebar, account menu, or approval-mode selector.
- Restart the app and check again.
Expected behavior
The Codex app UI should switch to Chinese consistently after selecting 中文, or the app should clearly indicate which surfaces are not yet localized and whether a restart is required.
Actual behavior
The setting shows 中文 as selected, but the UI still displays English strings, including:
- New chat / Pull requests / Sites / Scheduled / Plugins
- Usage remaining / Show pet / Settings / Log out
- Approval mode dialog and descriptions
Restarting does not appear to make the language choice take effect.
Environment
- Product: Codex macOS app
- App version: 26.721.41059
- Build: 5848
- Bundled Codex CLI: 0.141.0
- Date observed: 2026-07-27
Additional feedback
Please prioritize release stability and regression testing over very frequent updates. Recent updates feel increasingly prone to user-facing regressions. A staged rollout/rollback strategy and localization smoke tests for all major UI surfaces would make the desktop app much more reliable.
