Open-Source Tool RemoveMacAI Deletes macOS 27 On-Device AI Models

KEY FACTS

macOS 27 removes the master Apple Intelligence toggle, and models remain on disk even after features are turned off.
The open-source tool RemoveMacAI can disable related features and delete already-downloaded AI models.
The tool uses a configuration profile to prevent macOS from re-downloading deleted models.
After the profile is removed, settings are restored and the system re-downloads models when features need them.
The tool makes no network requests and collects no data, and supports Homebrew installation and rollback.

PHYSIX OBSERVATION

Apple keeping AI models local and offering no master toggle amounts to treating user acceptance as the default. RemoveMacAI blocks downloads with a configuration profile plus port redirection, showing that the right to opt out of system-level AI is becoming a hard requirement. For users, it is control over privacy and storage; for Apple, it is the first tool-driven backlash against its on-device AI strategy.
