RemoveMacAI is an open-source utility for Apple silicon Macs running macOS 27 that disables Apple Intelligence features and removes their downloaded models. Its developer says macOS may continue to count the files in Storage settings until the system deletes them, and the tool can be reverted.

An open-source utility called RemoveMacAI can disable Apple Intelligence features and remove their downloaded models from supported macOS 27 Macs, according to its GitHub project documentation. The tool addresses a limitation described by its developer: macOS 27 has no single switch for turning off Apple Intelligence, and disabling features does not itself remove their models from disk.

RemoveMacAI is designed for Apple silicon and is listed as tested on macOS 27.0. The project says macOS 26 and earlier are not supported; users on macOS 27.0.1 need version 0.2.3 or later. The utility displays the current feature state and asks for confirmation before making changes. It then opens System Settings so the user can approve a configuration profile, which macOS requires for the operation.

According to the project, the profile applies Apple restriction keys where available and forces certain settings that lack a restriction key. RemoveMacAI also removes Apple Intelligence foundation models and models associated with image generation, Genmoji, Spatial Photos, Photos Clean Up and Xcode code completion. Its download block is intended to stop macOS from downloading the removed models again. The developer says System Integrity Protection remains enabled and the tool does not directly modify files under /System.

The project offers commands to inspect feature status and model sizes, preview changes with a dry run, leave selected features enabled, and revert the changes. It says the profile and download block persist across macOS updates, and removing the profile restores the previous settings. RemoveMacAI is distributed through a GitHub installer and a Homebrew tap; its documentation says releases are built by GitHub Actions and carry build provenance attestations.

Storage Gains Come With Feature Losses

The utility gives users who want to reclaim storage a way to remove models that can remain after Apple Intelligence features are turned off. The potential space recovered depends on the models present on an individual Mac; the project provides a status command to show the on-disk model sizes, but the source material does not give a single storage figure that applies to all users.

Using the tool also disables a broad set of functions, not just one assistant setting. The project lists Siri features, Writing Tools, Genmoji, Image Playground, the ChatGPT extension, summaries in several apps and notifications, Mail smart replies, inline text predictions, Spatial Photos, Photos Clean Up and Xcode predictive code completion. It also warns that apps relying on Apple’s on-device models, Visual Intelligence and natural-language editing in Calendar will stop working. Users need to weigh that loss of functionality against the storage they may recover.

There is a timing caveat: RemoveMacAI’s developer says Apple’s asset service releases the models immediately, but macOS deletes the files on its own schedule. Storage settings may therefore keep counting them under Apple Intelligence after the removal process. The project also says Dictation remains available because its speech models are separate.

How the macOS 27 Tool Works

RemoveMacAI’s documentation describes macOS 27 as lacking a single control that disables all Apple Intelligence features. The tool uses a configuration profile to apply restrictions and alter settings, then removes model assets through Apple’s asset service. To prevent a later re-download, the profile redirects model downloads to a closed local port, according to the project.

The developer says the utility makes no network requests and collects no data. Its installer downloads the latest release, checks its SHA-256 checksum and runs it from a temporary directory; the project says it does not install the program as part of that process. These are claims in the project’s own documentation, rather than findings from an independent security review. The repository credits the separate project pared, by 4evy, with earlier work mapping the asset service, model sets and some settings keys.

The changes are reversible using the tool’s revert command; Homebrew users can then uninstall the package. The source material says macOS updates do not remove the profile, so the disablement and download block are intended to persist until the user reverts them.

““macOS 27 no longer has a single switch for Apple Intelligence, and its models stay on disk after the features are turned off.””

Deletion Timing and Model Sizes Vary

The project does not specify how long macOS may take to delete released model files, or how much storage a particular user will recover. It says the status command can report the sizes of models on disk, but Storage settings may continue to include them until macOS completes deletion. The exact delay and storage total are not stated.

The source material is the tool developer’s own documentation. It does not provide independent testing of the utility’s security claims or confirm how every listed feature behaves across different apps and system configurations. Users should check the project’s supported macOS versions and release notes before proceeding, especially because macOS 27.0.1 requires version 0.2.3 or later.

Check Compatibility Before Reverting

Users considering RemoveMacAI can first run its status command to review Apple Intelligence features and the model sizes reported on their Mac. The project also provides a dry-run option to display proposed changes without applying them. The tool requires approval of its configuration profile in System Settings before it proceeds.

After removal, users may need to wait for macOS to update the storage accounting. Anyone who wants the features back can run the revert command; the project says macOS may then download models again when a feature needs them. Further details about deletion timing and the storage recovered on individual systems remain dependent on macOS and the models present.

Key Questions

Which Macs and macOS versions does RemoveMacAI support?

The project lists Apple silicon Macs running macOS 27 as supported and says it tested the tool on 27.0. It does not support macOS 26 or earlier. For macOS 27.0.1, the project specifies version 0.2.3 or later.

Does removing the models mean storage settings update immediately?

No. The developer says Apple’s asset service releases the models right away, but macOS deletes the files on its own schedule. Storage settings may continue to count them under Apple Intelligence until that deletion is complete.

What stops working if Apple Intelligence is disabled?

The project lists features including Writing Tools, Genmoji, Image Playground, summaries, Photos Clean Up and Xcode predictive code completion. It also says apps using Apple’s on-device models, Visual Intelligence and Calendar’s natural-language editing will no longer work. The exact effects depend on the feature or app involved.

Will Dictation still work?

According to the project documentation, yes. Dictation is a separate setting, and its speech models are not removed by RemoveMacAI.

Can the changes be undone?

Yes. The project provides a revert command that removes the profile and restores the previous settings. Its documentation says macOS can download models again when a feature needs them.
