ChatGPT and Codex gain Apple Messages access on Mac

OpenAI released an Apple Messages plugin on August 20, 2026, giving ChatGPT Work and Codex direct access to conversations stored in the Messages app on a Mac. The plugin can search and summarize chats, draft replies, and send messages after receiving the required macOS permissions.

The release turns personal and business conversations into another surface where an AI agent can retrieve context and take action. OpenAI keeps approval enabled for every outgoing message by default and warns that persistent approval removes the user’s final review step.

Key takeaways

• The plugin can read and search iMessage, SMS, and RCS conversations available through Messages on a Mac.
• It can find, summarize, draft, and send messages from ChatGPT Work or Codex.
• Availability covers all ChatGPT plans, but the initial release requires the Apple Silicon build of the macOS desktop app.
• Regular ChatGPT chats, the web and mobile apps, Codex CLI, and the IDE extension cannot use the integration directly.
• Managed-workspace administrators can disable Apple Messages through the existing Computer Use control.

Apple Messages becomes an agent surface

Users install the plugin from the ChatGPT plugin directory, start a new Codex or ChatGPT Work conversation, and grant the requested macOS permissions. They can then ask the agent to locate an old exchange, summarize unread messages, prepare a response, or send an approved reply through Apple’s Messages app.

The integration covers iMessage alongside SMS and RCS conversations visible on the Mac. It does not turn Messages into a remote interface for contacting ChatGPT, and it does not operate inside ordinary ChatGPT chats.

Access is broad but tied to Apple Silicon

OpenAI lists the plugin as available on all plans in the ChatGPT desktop app for macOS. The initial build supports Apple Silicon Macs only, excluding Intel hardware.

The capability also stays local to the desktop surface: it is not directly available through ChatGPT on the web or mobile, Codex CLI, or the Codex IDE extension. A user must start a new supported conversation after installing the plugin before its tools become available.

Approval remains the critical control

By default, ChatGPT presents the proposed message and recipients for approval. “Allow once” covers a single send, while persistent approval lets the agent send future messages to the selected chat without another confirmation.

OpenAI explicitly advises retaining per-send approval for conversations that may contain untrusted or misleading instructions. Messages are external input, so a malicious or confusing text could influence an agent’s interpretation. Removing the confirmation step also raises the cost of recipient mistakes, incorrect summaries, and tone errors.

Users can revoke persistent permission under Settings, Computer use, and the Messages management panel. OpenAI also documents a known conflict: tasks configured with Full access or another mode that suppresses approval prompts may fail to display the confirmation required for sending.

What workspace administrators should review

Managed organizations can disable the integration with the existing Computer Use control. Administrators should decide whether message access fits their data-handling rules, particularly when staff mix personal and business conversations in the same Messages database.

Teams that enable it should preserve send approvals, limit access to appropriate accounts, and test retrieval with non-sensitive conversations first. The immediate operational question is whether the productivity gain from searchable message context outweighs the additional communication and privacy surface created by agent access.
