OpenAI Adds Apple Messages Plugin to ChatGPT for Mac

OpenAI has released a new Apple Messages plugin for ChatGPT on macOS, enabling the assistant to read, search, and send messages directly from a user's Mac. The integration works across iMessage, SMS, and RCS, according to OpenAI's release notes.

What the plugin does

The Apple Messages plugin lets ChatGPT read and search Messages conversations on a Mac and prepare or send new messages on the user's behalf through the Messages app. OpenAI says the feature is available on all subscription plans within the ChatGPT desktop app for macOS, and it also works inside ChatGPT Work and Codex.

The plugin does not enable remote interaction with ChatGPT through Messages, and it does not function in standard ChatGPT chat conversations — it is scoped specifically to the desktop app's plugin system. For now, it only works on Apple silicon Macs; Intel-based Macs are not supported.

Approval and privacy controls

Given the sensitivity of granting an AI model access to personal message history, OpenAI says sending is gated by user approval by default — ChatGPT will only send a message after the user confirms both the message content and its recipients.

OpenAI's plugin guide, referenced in the release notes, outlines risks associated with granting persistent approval, steps for revoking plugin access, and a known issue in which certain automated tasks can disable approval prompts. OpenAI has not disclosed further technical details on how message data is processed or stored, and no independent security review of the plugin has been published.

Other changes in this release

The same update bundles several unrelated features:

• Pinned chat sync: Pinned conversations now stay synchronized between the ChatGPT desktop app and iOS.
• Codex thread snapshots: Users can share a read-only, point-in-time snapshot of a local Codex thread. Snapshots from personal accounts are accessible to anyone with the link; workspace snapshots are restricted to workspace members. OpenAI says Codex redacts known secret patterns but recommends manual review before sharing, since sensitive data could remain.
• Site co-editing: Workspace members can now be invited to co-edit a published ChatGPT-hosted Site, with owners retaining control over access, settings, analytics, and version rollback.
• Custom Site URLs: Some Site owners can change their hosted URL without redeploying; the previous URL redirects automatically.
• Computer History expansion: A feature introduced last week is expanding to Pro, Business, and Enterprise users in the EEA, Switzerland, and the UK. It requires Memories to be enabled and remains off by default.

No pricing changes accompanied this update.

What this means

This is a product feature addition to the existing ChatGPT desktop app, not a new model release — it changes how users interact with ChatGPT on macOS rather than altering any underlying model weights. The integration signals OpenAI's continued push toward agentic, OS-level assistants that can act on a user's behalf across native apps, following a similar pattern to browser and file-system integrations rolled out earlier in 2026.

The approval-gating and known bypass issue in automated tasks are worth watching: any AI system with read/write access to personal communications carries real risk if permission controls fail. Apple silicon-only support also suggests the plugin relies on system-level APIs not uniformly available on older Intel Macs, which may delay broader rollout.
