An open-source tool lets you delete 12GB of Apple Intelligence data on macOS

A new open-source command line tool called RemoveMacAI can delete Apple Intelligence data and disable its features on macOS. The developer, who announced the tool on Reddit, explained that the one-time Settings toggle for disabling Apple Intelligence was removed in macOS 27, and the AI models now stay on disk while features are split across multiple settings panes. RemoveMacAI turns off Siri, Writing Tools, Genmoji, Image Playground, the ChatGPT extension, and all summaries, then deletes the models (claimed to be about 12GB, though one user found 35.05GB) and prevents macOS from re-downloading them. A "removemacai revert" command can undo all changes. The developer claims the changes persist across macOS updates and that Dictation still works. The tool also includes a "removemacai status" command to show the size of each AI model.
