Overview
- The tool, which the developer published on Sunday, October 4, automates disabling Apple Intelligence on macOS 27, removes its locally stored models and blocks immediate re‑downloads through a configuration profile the user must approve.
- Reporters and users confirm removemacai typically reclaims about 10–12 GB of disk space though some Macs report much larger Apple Intelligence footprints, and Storage may lag before showing the freed space.
- RemoveMacAI works without turning off System Integrity Protection or modifying /System files: it uses Apple’s asset service to remove models and redirects model downloads to a closed local port so macOS cannot immediately fetch them again.
- Running the tool disables many built‑in features — including Siri (and Hey Siri), Writing Tools, Genmoji, Image Playground, ChatGPT extension, Mail/Messages/Safari/Notes summaries, Photos Clean Up and Xcode predictive completion — and changes are reversible with a 'removemacai revert' command.
- The project is open source and installable via a one‑line curl or Homebrew and has gained wide attention, but the developer warns it depends on restriction keys deprecated in macOS 26.4 that Apple could change in future updates, which could break the method.
