RemoveMacAI, an open-source utility for Apple silicon Macs running macOS 27, can disable Apple Intelligence features and remove their downloaded models. The project says macOS may continue counting the deleted models in Storage settings until it removes the files on its own schedule; all changes can be reversed.

The open-source RemoveMacAI utility can turn off Apple Intelligence features and remove their downloaded models from supported macOS 27 Macs, addressing a storage issue described by the project: disabling the features does not itself remove the models. The tool requires user approval for a configuration profile, and its developers say its changes can be reversed.

According to the project’s GitHub documentation, macOS 27 no longer provides a single switch to turn off all Apple Intelligence features, and downloaded models can remain on disk after features are disabled. RemoveMacAI applies restrictions for supported features, removes the associated models, and blocks macOS from downloading those models again. It is for Apple silicon and is not supported on macOS 26 or earlier. The project says it was tested on macOS 27.0; version 0.2.3 or later is needed for macOS 27.0.1.

The utility covers Siri, Writing Tools, Genmoji, Image Playground, Apple Intelligence summaries and smart replies, Photos Clean Up, Spatial Photos, Xcode predictive code completion and other listed features. The project says this also affects apps that use Apple’s on-device models, Visual Intelligence and natural-language editing in Calendar. Dictation remains available, because it is a separate setting and its speech models are not removed.

RemoveMacAI displays the current state and asks for confirmation before making changes. It then opens System Settings so the user can approve the configuration profile macOS requires. The project says the tool removes models through Apple’s asset service, leaves System Integrity Protection enabled and does not directly modify files under /System. It describes its installer as downloading a release, checking its SHA-256 checksum and running it from a temporary directory rather than installing the utility itself.

The Storage Trade-Off for Mac Users

The utility addresses a gap between turning off an AI feature and reclaiming the disk space its models occupy. For people who do not use Apple Intelligence, or who need to recover storage, removing those downloads may be useful. The change also comes with a functional cost: Apple Intelligence features and other capabilities that rely on Apple’s on-device models will stop working.

Users should not treat the Storage screen as an immediate measure of whether the cleanup worked. RemoveMacAI’s documentation says Apple’s asset service releases the models, but macOS deletes the files on its own schedule. Until that happens, System Settings may still count the models under Apple Intelligence even after they have been released for removal. The project’s reported behavior is not an independent test of the tool.

How the Profile Blocks Model Downloads

RemoveMacAI relies on a configuration profile to apply Apple restriction settings and force settings for which, according to the project, no restriction key exists. The profile also redirects model downloads to a closed local port. The project says this prevents macOS from downloading removed models again; removing the profile restores the previous settings, and macOS can download models again when a feature needs them.

The project says the profile persists across macOS updates. Its documentation provides commands to inspect status, preview changes with a dry run, leave selected features enabled, turn features off and revert all changes. Users who installed the tool through Homebrew can remove it with Homebrew after reverting. The project also provides a GitHub Actions build-provenance attestation check for release downloads and credits the separate pared project for work mapping Apple’s asset service and model sets.

““All changes can be reverted.””

Storage Counts May Lag Removal

The available source is the project’s own GitHub documentation; it does not provide an independent audit or test results confirming the tool’s storage savings across different Macs. The exact time macOS takes to delete released model files is not specified, so users may not see disk space returned immediately. The documentation also does not quantify how much storage each supported model set occupies.

Some system services may remain loaded, and the project notes that a process named Siri can still appear because the Spotlight window runs under that process name in macOS 27. It is therefore not clear from a process name alone whether Apple Intelligence features are active. The project says it makes no network requests and collects no data, but that is also a statement from the project rather than an independently verified finding.

Check Status Before Reverting

Users considering the utility can consult its release notes and compatibility instructions, then use its status command or dry-run option to review the reported state and planned changes. Applying the profile requires approval in System Settings. Anyone who wants to restore the original setup can run the project’s revert command; macOS may then download models again when a feature requires them.

The project’s documentation identifies macOS 27.0.1 support as requiring version 0.2.3 or later. Future compatibility will depend on changes in macOS and the utility’s releases. The source material does not announce a separate Apple response or a date for when macOS will remove released files from Storage accounting.

Key Questions

Does RemoveMacAI work on every Mac?

No. The project lists Apple silicon Macs running macOS 27 as supported. It says macOS 26 and earlier are not supported. Version 0.2.3 or later is required for macOS 27.0.1.

Will Dictation stop working?

The project says Dictation remains available. It is controlled separately, and RemoveMacAI does not remove its speech models.

Why might Storage settings still show Apple Intelligence?

According to the project, Apple’s asset service releases the models immediately, but macOS deletes their files on its own schedule. Storage settings may keep counting them until that process is complete.

Can the changes be undone?

Yes. The project provides a revert command that removes its changes. The documentation says removing the profile restores the previous settings; macOS may download models again when a feature needs them.

What features or apps could be affected?

The listed effects include Siri, Writing Tools, Genmoji, Image Playground, Apple Intelligence summaries and smart replies, Photos Clean Up, Spatial Photos and Xcode predictive code completion. The project also says apps using Apple’s on-device models, Visual Intelligence and natural-language editing in Calendar will be affected.
