RemoveMacAI is a third-party tool for Apple silicon Macs running macOS 27 that disables Apple Intelligence features, removes their downloaded models and blocks macOS from downloading them again. The project says the changes can be reversed; it also cautions that Storage settings may continue to count the models until macOS deletes the files.

The developer of RemoveMacAI has published a tool for Apple silicon Macs running macOS 27 that disables Apple Intelligence features, removes their downloaded models and blocks macOS from downloading those models again. The project says macOS 27 no longer offers one switch to turn off all the features, and that switching them off does not itself remove the models from disk.

RemoveMacAI first displays the Mac’s current Apple Intelligence state and asks the user to confirm changes. It then opens System Settings so the user can approve a configuration profile, which the project says macOS requires. The tool applies Apple restriction settings where available and forces other feature settings off, then uses Apple’s asset service to remove associated models.

The project lists Siri and Writing Tools, Genmoji, Image Playground, the ChatGPT extension, summaries in several Apple apps and notifications, Mail smart replies, inline text predictions, Spatial Photos, Photos Clean Up and Xcode predictive code completion among the features it can disable. Models for Apple Intelligence, image generation and the listed features are removed. Users can preserve selected features, preview changes with a dry run or use the revert command to undo the changes.

According to the project, the profile redirects requests for removed models to a closed local port to prevent redownloading. It says System Integrity Protection remains enabled, files under /System are not directly modified, and the tool makes no network requests or collects no data. The project says its releases are built from Git tags with GitHub Actions and include build provenance attestations; it also documents SHA-256 checksum verification for downloads.

Reclaiming Space Without Redownloading

The tool addresses two separate issues for people who do not want Apple Intelligence: disabling the features does not necessarily remove their models, and macOS may download models again when a feature needs them. RemoveMacAI’s approach is intended to handle both by removing the model assets and keeping future download requests from succeeding while the profile remains installed.

That may matter on Macs where available storage is limited or where users prefer not to use on-device AI features. The trade-off is broader than a single settings switch: the project lists affected functions across Siri, Apple apps, Photos and Xcode, and says apps using Apple’s on-device model frameworks, Visual Intelligence and natural-language editing in Calendar will also stop working. Users should review that list before applying changes.

The storage result may not be immediate in System Settings. The project says Apple’s asset service releases the models promptly, but macOS deletes the files on its own schedule. Until that happens, Storage may still count the models under Apple Intelligence even after removal has been requested. The project advises checking its status output and warnings if removal fails or cannot be confirmed.

How the macOS 27 Method Works

RemoveMacAI’s documentation describes a change in the macOS 27 controls: there is no longer a single switch for Apple Intelligence, while downloaded models can remain after features are turned off. The tool is designed for macOS 27 on Apple silicon. The project says earlier macOS versions are unsupported; on version 27.0.1, it specifies version 0.2.3 or later of RemoveMacAI.

The profile is central to the method. The project says it applies Apple’s restriction keys and sets features for which no restriction key exists. It also persists across macOS updates, according to the documentation. Removing the profile restores the prior settings, and macOS can download models again when a feature needs them. The project acknowledges that some system services can remain loaded; in macOS 27, it says the Spotlight window runs as a process named Siri. A process with that name does not by itself mean all Apple Intelligence features are active.

The project credits RemoveMacAI’s underlying work to pared, a tool by 4evy that mapped the asset service, model sets and several settings keys. The repository also says the configuration can be reversed and provides a Homebrew installation option as well as a one-line installer. These are statements from the project’s documentation, rather than independent measurements of storage reclaimed on individual Macs.

“All changes can be reverted.”

Storage Reporting and Feature Effects

The project documentation does not give a single storage figure users can expect to recover. Model sizes that Apple’s asset service cannot report appear as unknown, and the time macOS takes to delete released files is not specified. As a result, the space freed and when it appears in Storage settings may vary by Mac and its installed models.

RemoveMacAI says model removal can fail or remain unconfirmed. In that case, it reports that the command exits with status 1 while leaving the configuration profile active; users are told to review warnings and check status before trying again. The available source material does not provide independent testing of the tool’s behavior across different Macs or future macOS releases. It also does not establish whether Apple will change the relevant settings or asset service in a later update.

The project says Dictation continues to work because it is separate and its speech models are not removed. It also lists several other affected capabilities, including apps built on Apple’s Foundation Models framework. The precise effects on an individual setup depend on which features and apps the user relies on.

Check Compatibility Before Applying

Mac users considering RemoveMacAI can first use its status command to see feature states and reported model sizes, and its dry-run option to preview changes. The project says users should confirm they are on supported Apple silicon hardware and a supported macOS version; its documentation calls for version 0.2.3 or later on macOS 27.0.1. Users who want to retain some features can list them with the keep option, though features that are already off remain off until turned on separately.

After applying changes, users can check status and review any warnings. If they decide to restore Apple Intelligence settings, the project documents a revert command and says macOS will download models again when a feature needs them. It remains unclear how quickly storage totals will update on each system, so the project’s reported model state and macOS Storage display may differ temporarily.

Key Questions

Which Macs and macOS versions does RemoveMacAI support?

The project lists Apple silicon Macs running macOS 27 as supported. It says macOS 26 and earlier are unsupported, and calls for RemoveMacAI version 0.2.3 or later on macOS 27.0.1.

Does Dictation stop working?

According to the project, Dictation remains available because it is a separate setting and its speech models are not removed.

Will Storage settings show the space as free immediately?

Not necessarily. The project says macOS deletes released model files on its own schedule, so Storage settings may continue counting them under Apple Intelligence until deletion is complete.

Can the changes be undone?

Yes. The project documents a revert option that removes the configuration profile and restores prior settings. It says macOS can download models again when a feature needs them.

Does turning off Apple Intelligence affect other features?

The project lists effects on Siri, Apple apps, Photos, Xcode predictive code completion, apps that use Apple’s on-device model framework, Visual Intelligence and natural-language editing in Calendar. Users should check the full feature list against their own use.
