The ChatGPT desktop app can now read your iMessage history and send messages on your behalf. OpenAI shipped the integration this week for Macs running Apple silicon, and Apple, a company it is reportedly
preparing to sue
, was not part of the announcement.
The plugin reads and searches Messages conversations on the machine, covering iMessage, SMS, and RCS, and can draft and send replies. It will also analyse the archive, summarising who you talk to and what you talk about, which is a different capability from writing a text and a considerably more revealing one.
Sending is gated by default. Each outgoing message requires explicit approval, and OpenAI has been clear that this is the setting it expects people to keep.
Yet, users can turn that off. Granting persistent approval lets the model send without asking, and OpenAI’s own guidance advises taking care before doing so, which is an unusual thing for a company to say about a feature it built.
There is also a known defect. OpenAI acknowledges that certain tasks can disable the approval prompt, meaning the safety mechanism has a failure mode the company has documented rather than fixed.
The integration is available across all plans in the desktop app, with fuller behaviour in ChatGPT Work and in Codex. It does not run on Intel Macs.
None of this required Apple’s cooperation, which is the part worth sitting with. The Messages database lives on the local disk, and an application with the right macOS permissions can read it, so OpenAI has built on an access route Apple grants rather than one it negotiated.
Apple has spent a decade marketing Messages on end-to-end encryption. That encryption protects messages in transit and at rest on the device; it does not protect them from software the user has authorised to read the de
