Turn off Apple Intelligence on macOS 27 and remove its downloaded models. macOS 27 no longer has a single switch for Apple Intelligence, and its models stay on disk after the features are turned off. Remove Mac AI turns the features off, removes the models and prevents macOS from downloading them again. All changes can be reverted.
Install with one command: `curl -fsSL https://raw.githubusercontent.com/omlahore/RemoveMacAI/main/install.sh | bash`. The script downloads the latest release, verifies its SHA-256 checksum, and runs it from a temporary directory. Nothing is installed. Every release is built from its tag by GitHub Actions and carries a build provenance attestation.
Features turned off include Siri, Writing Tools, Genmoji, Image Playground, the ChatGPT extension, summaries in Mail, Messages, Safari, Notes, and notifications, Mail smart replies, inline text predictions, Spatial Photos, Photos Clean Up, and Xcode predictive code completion. Models removed include Apple Intelligence foundation models and those for image generation, Genmoji, Spatial Photos, Photos Clean Up, and Xcode code completion.
A configuration profile applies Apple's restriction keys and forces settings with no restriction key. Models are removed through Apple's asset service. System Integrity Protection stays enabled, and no files under /System are modified directly. The profile redirects downloads of removed models to a closed local port, preventing re-download. Removing the profile restores previous settings. Remove Mac AI makes no network requests and collects no data.
