ChatGPT adds an Apple Messages plug-in with approval controls

An Apple Messages plug-in was released on August 20, 2026 for all ChatGPT plans on the macOS desktop app. It can read and search iMessage, SMS and RCS conversations and prepare and send messages.

By default, user approval is required for each message and its recipients; the official notes flag a known issue about persistent approval risk and tasks that disable prompts.

A general assistant has now become a consequential communication tool: recipient resolution, user intent and revocation are operational controls. Keep approvals on, minimise access, log payloads and recipients, and test for prompt injection. No separate price was announced; the Mac desktop environment is required.
