RemoveMacAI Deletes Apple Intelligence in One Command to Free Mac Space
An open-source command-line tool called RemoveMacAI deletes Apple Intelligence features and their stored models from Macs running macOS 27 to recover disk space. The Verge
The issue comes from a change in macOS 27. Apple removed the single Settings toggle that once turned off Apple Intelligence in one place. In macOS 27 the controls are split across different Settings panes, and the models, the large files that power on-device AI, stay on disk even after you switch the visible features off. The Verge
RemoveMacAI takes a direct approach. It switches off Siri, Writing Tools, Genmoji, Image Playground, the ChatGPT extension, and system summaries in one operation. It then deletes the Apple Intelligence models from local storage and blocks macOS from downloading them again.
That is aimed at administrators and users with tight disks. Storage is not free. These foundation models are large, they persist on the drive, and the OS will fetch them again unless that download is explicitly blocked.
According to its developer, the changes hold across macOS updates. Dictation keeps working after removal, which matters for accessibility and for people who use voice input but do not want generative features. Both points come from the developer's own documentation rather than independent testing.
The interface is spare. A removemacai status command lists the size of each AI model found on the Mac. A removemacai revert command turns the features back on and allows the models to download again. The developer puts the foundation models at about 12GB. The Verge
The project is published on GitHub under omlahore/RemoveMacAI. GitHub It describes its goal as turning off Apple Intelligence on macOS 27 to get disk space back with one command that is fully reversible. The code was published on Oct. 2, 2026, and drew wider attention on Oct. 5.
Disk use is the central tension. Apple documentation cited in September puts the storage need for the latest Apple Intelligence features at up to 14GB on Macs with an M3 chip or later. That same month MacRumors reported some macOS 27 installs were using 30GB or more. MacRumors The difference comes down to base models versus extra assets, languages, and cached copies. The exact footprint varies by setup.
Apple still documents manual controls. It publishes a Mac Help guide titled "Turn off and restrict access to Apple Intelligence features." For Siri, its steps are to open System Settings, click Siri in the sidebar, click Turn Off Siri, then confirm a second time. Apple also notes Apple Intelligence on macOS 27 is not available in all languages or regions. For checking storage in general, Apple says in macOS Ventura 13 or later to choose System Settings from the Apple menu, click General in the sidebar, then click Storage.
The broader context here is familiar to anyone who manages Mac fleets. Vendors now ship large on-device models as part of the base OS, with small switches for each feature but no single uninstall path. Users get more capability. Administrators get more disk pressure and more panes to audit.
For technical teams, the appeal is practical rather than philosophical. A scriptable method that can run automatically, strips gigabytes of model data, shows per-model size, and stops silent re-download fits how teams already handle language packs and Xcode simulators. Reversibility is what makes it usable. A one-way delete would be risky. A revert command makes testing cheap.
In my view, this kind of tool arrives quickly whenever model size jumps. I watched the same pattern at home as phones and laptops filled with offline media and app caches. My children did not read storage warnings. They just kept installing until the device complained. Tools that show the cost clearly, here down to each model, tend to last beyond the release that prompted them because they restore a choice the default screens made harder to make.
