RemoveMacAI

Turn off Apple Intelligence on macOS 27 and remove its downloaded models.

macOS 27 no longer has a single switch for Apple Intelligence, and its models stay on disk after the features are turned off. RemoveMacAI turns the features off, removes the models and prevents macOS from downloading them again. All changes can be reverted.

RemoveMacAI turning off Apple Intelligence

Demo video

Install

curl -fsSL https://raw.githubusercontent.com/omlahore/RemoveMacAI/main/install.sh | bash

The script downloads the latest release, verifies its SHA-256 checksum and runs it from a temporary directory. Nothing is installed.

Every release is built from its tag by GitHub Actions and carries a build provenance attestation. To check that a download came from this repository's source:

gh attestation verify removemacai-darwin-arm64.tar.gz -R omlahore/RemoveMacAI

With Homebrew:

brew install omlahore/tap/removemacai
removemacai

RemoveMacAI shows the current state and asks for confirmation. It then opens System Settings to install its configuration profile, which macOS requires the user to approve, and removes the models.

Usage

Command Description
removemacai Show the current state, then turn Apple Intelligence off
removemacai status Show each feature and the size of the models on disk
removemacai off --keep <features> Leave the listed features on
removemacai off --dry-run Show the changes without applying them
removemacai revert Undo all changes
removemacai features List the feature names accepted by --keep

To revert with the one-line installer:

curl -fsSL https://raw.githubusercontent.com/omlahore/RemoveMacAI/main/install.sh | bash -s revert

What it changes

Features turned off: Siri (including "Hey Siri" and the menu bar icon), Writing Tools, Genmoji, Image Playground, the ChatGPT extension, summaries in Mail, Messages, Safari, Notes and notifications, Mail smart replies, inline text predictions, Spatial Photos, Photos Clean Up and Xcode predictive code completion.

Models removed: the Apple Intelligence foundation models and the models for image generation and Genmoji, Spatial Photos, Photos Clean Up and Xcode code completion.

How it works

RemoveMacAI makes no network requests and collects no data.

FAQ

Does dictation still work? Yes. Dictation is a separate setting, and its speech models are not removed.

Do macOS updates undo the changes? No. The profile, including the download block, persists across updates.

Storage settings still lists Apple Intelligence after the models were deleted. Apple's asset service releases the models right away, but macOS deletes the files on its own schedule. Until then, System Settings > General > Storage keeps counting them under Apple Intelligence.

Why is a process named Siri still running? In macOS 27 the Spotlight window runs as a process named Siri. Some system services also stay loaded; they are protected by System Integrity Protection.

What stops working? The features listed above, apps that use Apple's on-device models (the Foundation Models framework and the Use Model action in Shortcuts), Visual Intelligence and natural-language editing in Calendar.

Requirements

Apple silicon.

macOS Status
27 Supported, tested on 27.0. On 27.0.1, use 0.2.3 or later.
26 and earlier Not supported

Uninstall

Run removemacai revert, then brew uninstall removemacai if it was installed with Homebrew.

RemoveMacAI
What is this?RemoveMacAI is a macOS 27 tool that turns off Apple Intelligence features (Siri, Writing Tools, Genmoji, image generation, and more), deletes the AI models already downloaded for them, and blocks macOS from downloading those models again, with every change reversible.
Is this a GUI app or something I run from Terminal?It ships as both a native macOS app and a CLI called removemacai, with commands like status, off, revert and features for scripting or terminal use.
Do I need Apple Silicon for this?Yes, Apple Silicon is required, and only macOS 27 is supported; on 27.0.1 specifically you need version 0.2.3 or later.
Will this work on an Intel Mac or on macOS 26?No, macOS 26 and earlier are not supported, and since Apple Silicon is a requirement, Intel Macs are excluded too.
Does RemoveMacAI send any of my data anywhere?No, it runs entirely locally: it makes no network requests of its own and collects no data.
What exactly does it disable?It turns off Siri (including Hey Siri), Writing Tools, Genmoji, Image Playground, the ChatGPT extension, summaries in Mail/Messages/Safari/Notes, inline text predictions, Spatial Photos, Photos Clean Up and Xcode predictive code completion, and removes the matching on-device models.
Can I undo the changes later?Yes, running removemacai revert undoes everything, and macOS will download the models again the next time a feature needs them.
Does turning this off also disable dictation?No, dictation uses a separate setting and its speech models are left untouched.
How does it stop macOS from re-downloading the removed models?The installed configuration profile redirects each model's download request to a closed local port, so Apple's asset service cannot fetch it again until the profile is removed.
