macOS tools

Key features

• The app is signed with a Developer ID and notarized by Apple, and is a universal binary (Intel + Apple Silicon).
• It turns hand‑editing /.codex/auth.json and config.toml into one save: Official OpenAI and your custom provider both stay configured, switching changes the default route without retagging saved conversations.
• It ships quick presets for popular Chinese LLM providers and can run a local adapter that bridges Chat‑Completions‑only APIs to the Responses protocol Codex speaks.
• Don't ask Codex itself to edit its provider config in chat — use this app to switch, it's far more reliable.
