Reclaiming disk space: open-source tool RemoveMacAI strips Apple Intelligence from macOS
In brief: Following Apple's removal of the global toggle for Apple Intelligence in macOS 27, local foundation models have remained locked on user SSDs even when not in use. A new open-source command-line utility called RemoveMacAI now allows users to disable every AI feature, wipe between 12GB and over 35GB of model data, and prevent automatic background downloads without breaking System Integrity Protection.

The disappearance of the master switch in macOS 27
Until the previous release of macOS, Mac users who chose not to use Apple's generative AI features could easily turn them off through a single toggle in System Settings. With macOS 27 Golden Gate, however, Apple eliminated this unified control. AI features have been dispersed across roughly a dozen distinct preference panes, with some options buried inside Screen Time settings.
More critically, disabling individual toggles does not reclaim local storage. The underlying foundation models stay cached on disk, permanently occupying substantial SSD space with no native operating system mechanism provided to delete them.
How RemoveMacAI works without breaking SIP
In response to these constraints, independent developer Om Lahore created RemoveMacAI, an open-source command-line utility published on GitHub. The tool automates what macOS no longer permits out of the box: it disables Siri, Writing Tools, Genmoji, Image Playground, the ChatGPT integration, and automatic summarization, subsequently purging the model weights and blocking background re-downloads.
As reported by Ars Technica, the script avoids modifying protected paths under /System and keeps System Integrity Protection (SIP) fully active. It relies on a user-approved configuration profile and Apple's native asset management services. The utility is completely reversible via a removemacai revert command, while preserving non-generative features such as standard voice dictation.
From 12 to 35 gigabytes: the storage footprint on enterprise laptops
While the developer initially estimated the freed space at roughly 12GB, the actual storage footprint can be far larger. Testing conducted by The Verge on a MacBook Air revealed that Apple Intelligence assets can consume over 35GB of SSD capacity.
On workstations equipped with baseline 256GB or 512GB drives, dedicating such a large portion of non-upgradable storage to unused background models poses a concrete operational hurdle. For engineers and digital creators managing Docker containers, local databases, and multimedia assets, this locked storage represents an unnecessary overhead.
The debloating paradox hits macOS
The utility rapidly surpassed 1,700 GitHub stars, sparking wide discussion across platforms like Hacker News and Reddit. Many developers drew comparisons to Windows debloating scripts, noting the irony that macOS power users now rely on third-party shell utilities to strip away bundled generative software.
This trend underscores an emerging tension in client computing: as hardware vendors push system-level generative AI to drive adoption, technical users and organizations increasingly demand sovereign control over their hardware resources.
Mocchi's take
Across the developer machines and corporate fleets we configure, storage efficiency and endpoint governance are critical priorities. Apple's decision to lock dozens of gigabytes behind non-removable local models creates real friction, particularly for organizations running baseline SSD configurations or working under compliance standards where unmonitored on-device AI must be controlled. Reversible, architecture-safe utilities like RemoveMacAI highlight an important reality: client-side intelligence should be a configurable asset, not an involuntary infrastructure cost imposed on the workstation.
