macOS 26 gave you a single switch to disable Apple Intelligence entirely. macOS 27 removed it, and what replaced it is a spread of individual toggles across multiple settings menus, including Screen Time. Turning those features off does not guarantee the downloaded AI models actually leave your drive.
That gap is what RemoveMacAI, a free open-source utility from GitHub user omlahore, is designed to close.
What Apple Removed
Apple’s master AI toggle is gone in macOS 27, and the models stay behind even when features are off.
In macOS 27, Apple eliminated the system-wide Apple Intelligence off-switch that existed in earlier releases. Users who want to disable these features must now work through roughly a dozen individual settings scattered across the operating system, according to reporting from The Verge and MacRumors. Disabling those features through Apple’s own menus does not necessarily trigger removal of the foundation models already downloaded to your Mac.
Those models are not small. Apple’s stated storage requirement reaches up to 14GB on Macs with an M3 chip or later. Some users running macOS 27 have reported storage readouts above 30GB, figures that likely include image-generation, photo-processing, Genmoji and developer-related assets beyond the core foundation models, per MacRumors reporting from September 2026.
What RemoveMacAI Does
The tool automates disabling AI features, deleting their models and blocking re-downloads through a single Terminal utility.
RemoveMacAI runs in Terminal and targets a broad set of Apple Intelligence features. Those features include Siri enhancements, Writing Tools, Genmoji, Image Playground, the ChatGPT extension, Mail and Messages summaries, notification summaries, inline text predictions, Photos Clean Up, Spatial Photos and Xcode predictive code completion.
According to the project documentation, it deletes the associated model assets and then blocks macOS from downloading them again. The process requires users to approve a configuration profile in System Settings. Per the developer, the tool works through Apple’s asset-management mechanisms rather than modifying protected system files directly.
Before running the removal, the removemacai status command reports the size of individual AI models currently on the drive. If you change your mind later, removemacai revert is intended to undo all changes and allow the models to download again, according to the project documentation.
The storage recovered depends on what is installed. The developer estimates roughly 12GB; Apple’s own stated requirement reaches up to 14GB on M3-and-later Macs; and some user reports, cited by MacRumors in September 2026, have shown totals above 30GB.
Compatibility and Caveats
The tool works on Apple silicon Macs running macOS 27, but a documented compatibility risk is already on the record.
RemoveMacAI requires an Apple silicon Mac running macOS 27. Users on macOS 27.0.1 specifically need version 0.2.3 or later, per the project repository. macOS 26 and earlier are not supported.
The developer says changes persist across macOS updates and that Dictation continues to function after removal. Those are self-reported claims and have not been independently verified.
One documented risk warrants attention. MacRumors reported that some configuration-profile restriction keys the tool relies on were deprecated by Apple in macOS 26.4, which could affect compatibility in future system releases. Before approving any configuration profile or running the install command, inspect the source code and confirm your macOS version matches the listed compatibility. Keep a current backup. The tool is free and MIT-licensed, and its open-source availability makes it auditable, though that is not a substitute for caution.
If you are running macOS 27 on Apple silicon and have no use for Apple Intelligence, RemoveMacAI offers a more thorough cleanup than Apple’s own settings currently allow. Future macOS updates could break compatibility without warning, given Apple’s deprecation of certain profile keys , a reminder of the computer problems that arise when system changes outpace user controls. The need for a third-party command-line tool at all follows directly from macOS 27 shipping without a system-wide off-switch.
