macOS 27 Code Reveals a Siri Engine Swap for Claude or ChatGPT
Code in macOS 27 Golden Gate RC reveals a Model Manager Services protocol that hands Siri's 'brain' to a third-party model with native Apple system permissions. The architecture was mandated by the EU's Digital Markets Act.
Code in macOS 27 Golden Gate Release Candidate reveals a Model Manager Services protocol that hands Siri's 'brain' to a third-party model: Claude or ChatGPT would receive native Apple tools and could read mail, create reminders, and send messages. ChatGPT support has already been found in the code; Claude support is in development. The feature is currently hidden from users. The architecture was dictated by the EU's Digital Markets Act (DMA).
As a vibe coder, I see this as a turning point: Apple is building the model switcher directly into the OS, not as a layer on top. This isn't a limited-access ChatGPT mode — it's a different engine with the same system-level permissions as Siri.
