Summary
On Sept. 13, developer pdfu showed Claude running as a Siri extension on macOS Golden Gate through Apple’s private Model Delegation API, demonstrating a working but unsupported integration.
In the setup, Claude handles generative tasks such as creating a CSV file, while Siri still executes native system actions like setting reminders.
The implementation depends on a private App Intents interface and a restricted Apple entitlement, meaning ordinary users cannot switch Siri to Claude through any public Mac or iPhone setting.
That makes the demo separate from Apple’s June 8 Siri AI developer testing, which is built around Apple Foundation Models and Private Cloud Compute rather than Anthropic’s model.
Requests routed to Claude may leave Apple’s Private Cloud Compute environment for Anthropic’s servers, and the private hooks could change in future macOS or iOS 27 releases.
