Use an Apple silicon Mac with the current ChatGPT desktop app. Open Work or Codex and find Plugins. Search for Apple Messages, inspect its scope and install it if available to your plan and workspace. Complete any macOS permissions or app connection steps shown.

Start with a narrow read-only request: ask for a conversation you remember and compare the result in Messages. If the plugin is absent, check desktop app updates and workspace permissions instead of assuming all ChatGPT surfaces include it.

1. Find a recommendation. Search my Messages for restaurant recommendations from June 2026. Return the sender, date and exact restaurant names. Do not send anything.
2. Meeting catch-up. Summarize my recent conversation with [person] about [topic]. Separate decisions, open questions and promises I made.
3. Group chat decisions. Read [group chat] from [date]. List decisions, unresolved items and tasks assigned to me, with message dates.
4. Draft a reply. Draft a short reply to [person] confirming [fact]. Show the text and recipient before any send action.

Keep each request limited to the people and time period you need. Check names, context and dates before relying on the summary.

A draft is a draft. If you ask the plugin to send, verify the recipients, text and attachments in the approval step. OpenAI says approval is requested by default before sending. For sensitive matters, open the original conversation yourself and send from Messages after review.

Disconnect the plugin when you no longer need it or if you connected the wrong account. Plugin permissions and availability can change with your workspace settings.
