Apple Removed the Apple Intelligence Off Switch in macOS 27 — So a Developer Built a CLI That Deletes It Anyway

For years, disabling Apple Intelligence was one toggle in System Settings. That ended with macOS 27: the single switch is gone, the models stay on the disk, and the individual features are split across different settings panes. An open-source command-line tool called RemoveMacAI, published on GitHub by developer omlahore, is now doing what the old toggle did — and it caught the attention of MacRumors and The Verge on October 5.

The developer's description, posted to Reddit and spotted earlier by MacRumors, is blunt: the tool deletes the Apple Intelligence models from the disk and turns the features off. Getting there manually is not trivial — the settings that govern Apple Intelligence are spread across roughly a dozen locations in System Settings, and several of them hide under Screen Time rather than anywhere Apple Intelligence-adjacent. That placement is easy to miss, which is precisely the friction the tool automates away.

The storage angle is the practical hook. The local models that power Apple Intelligence's on-device features occupy real disk space, and on smaller SSDs that space is not optional. MacRumors' headline framing — a removal tool that "frees Mac storage" — reflects the core use case: users who never touch Writing Tools or the cleaner Siri get the gigabytes back without hunting through settings panes. The Verge notes the tool effectively restores the pre-macOS 27 status quo.

There is a clear trade-off to state plainly: RemoveMacAI removes the features, not just the clutter. Anyone who uses on-device summarization, image tools or the refreshed Siri would need to reinstall or re-enable them after running it. And like any third-party tool that deletes system components, it carries the usual risk profile — it is an unofficial utility, not an Apple-supported path, so users should read the repo and back up before running it.

The episode says something larger about where the industry is. Just as enterprise teams are reaching for tools to police what AI agents do to their systems, individual users are now building tools to excise AI features they never asked for. Apple's on-device, privacy-first architecture was supposed to make AI integration unobtrusive; instead, the inability to say no with one click has produced a small ecosystem of workarounds. A power-user CLI is a modest form of pushback — but it is pushback all the same.
