Turn off Apple Intelligence and delete its models on your Mac. Optional tweaks for analytics, ads and pop-ups. A native app and CLI, and every change can be undone.
Turn off Apple Intelligence and delete its models. The app starts with just that. If you want to debloat further, it can also stop the analytics and ads, quiet the pop-ups, switch off other apps’ background updaters and get disk space back. You see every change before it happens, and every change can be undone.
Built on pared by 4evy, who did the hard work first: mapping Apple’s asset service, the model sets and the settings keys the Apple Intelligence part relies on.
It downloads the latest release, checks its SHA-256 checksum, puts RemoveMacAI in Applications and opens it.
To download it yourself instead, get RemoveMacAI.zip from the latest release, unzip it and drag RemoveMacAI to Applications. The app is not notarized, so the first time you open it macOS says it can’t verify it. Open System Settings > Privacy & Security, scroll down and click Open Anyway.
This runs the command-line version from a temporary folder and installs nothing. With Homebrew:
brew install omlahore/tap/removemacai
The app and the command line are the same program and share the same undo history. If you installed the app from the zip, choose RemoveMacAI > Install Command Line Tool… to get the removemacai command too.
What it does
The app opens on Apple Intelligence alone. Show More Tools in the sidebar brings in the rest.
Section
What you can turn off or change
Apple Intelligence
Siri, Writing Tools, Genmoji, Image Playground, ChatGPT, summaries in Mail, Messages, Safari, Notes and notifications, inline predictions, Spatial Photos, Photos Clean Up, Xcode predictive completion. The models are deleted and blocked from downloading again. Keep any feature you use.
Privacy
Mac Analytics, personalized ads, Improve Siri and Dictation, Improve Search, Spotlight internet results, Look Up suggestions, Safari search suggestions, Game Center
Annoyances
Clicking the wallpaper hiding every window, desktop widgets, the media keys, all Music launches (including AirPods; opt-in), iPhone Mirroring
Apple apps
Apple Music in the Music app, the Book Store, unused Apple apps in the Dock
Finder
File extensions, hidden files, the path and status bars, folders first, searching the current folder, the extension warning, .DS_Store files on network drives, emptying the Trash after 30 days, saving to your Mac instead of iCloud, the Library folder
Dock and windows
Recent apps, the auto-hide delay, bouncing icons, minimizing into the app icon, window animations, gaps between tiled windows, screenshot shadows
Typing
Autocorrect, smart quotes and dashes, the double-space period, automatic capitals, the accent menu on held keys
Background items
Updaters and helpers other apps install, such as Google’s updater, shown with what they run and switched off one by one
Storage
Old macOS installers, aerial wallpaper videos, iPhone and iPad update files, Xcode build data and device support, unavailable simulators, app caches, Time Machine local snapshots, and Apple’s optional apps (GarageBand and its sound library, iMovie, Keynote, Numbers, Pages)
Two presets get you started. Recommended turns Apple Intelligence, analytics and ads off and removes the pop-ups, and leaves alone anything you rely on. Maximum privacy adds Game Center and Safari’s search suggestions. Both add to what is already applied, and nothing changes until you review it.

Undo everything RemoveMacAI changed
removemacai app
Open the app
apply, undo, background and clean show the change first and ask. --dry-run shows it and stops, and --yes skips the question.
Tab completion for zsh, bash and fish is in completions. Each script says where it goes.
It holds the Apple Intelligence restrictions, the download block for removed models and the locked tweaks. Per-user tweaks such as Finder and Dock settings aren’t in the profile; removemacai apply sets those on each Mac. removemacai tweaks --json reports the state of every tweak for compliance scripts.
iPhone and iPad
export --for iphone or export --for ipad writes a profile for that device:
An unsupervised phone only honors the Siri and ChatGPT switches.
How it works
Locked settings (Apple Intelligence and the tweaks marked with a lock) go in one configuration profile that you approve in System Settings, because macOS requires that. Removing the profile undoes all of them.
Other settings are written the way defaults write writes them. RemoveMacAI first records each setting’s previous value in ~/Library/Application Support/RemoveMacAI/journal.json, and undo puts back exactly that value.
Models are removed through Apple’s asset service, and the profile points their downloads at a closed local port so macOS doesn’t fetch them again.
Storage cleanup moves files to the Trash, so they aren’t gone until you empty it. Unavailable simulators and Time Machine local snapshots are deleted right away by simctl and tmutil.
System Integrity Protection stays on, nothing under /System is modified, and RemoveMacAI collects no data. It makes no network requests, except to GitHub when you choose Check for Updates… in the app.
What it doesn’t do
Delete Apple’s built-in apps. They live on the sealed system volume. Removing them needs System Integrity Protection off, and a failed attempt can leave the Mac unable to start. RemoveMacAI quiets them instead and removes the optional apps that Apple lets you delete.
Mass-disable Apple’s background services. With System Integrity Protection on, macOS refuses to unload most of them, and many start again whenever an app asks for them. RemoveMacAI switches off the one that unloads cleanly (the media keys) and other apps’ background items.
FAQ
Does dictation still work?
Yes. Dictation is a separate setting, and its speech models are not removed.
Where do I use Photos Clean Up after keeping it enabled?
Open a photo in Photos, choose Edit, then Tools > Clean Up. Photos Clean Up is not a separate switch in System Settings.
Do macOS updates undo the changes?
The profile persists across updates. If an update resets one of the other settings, RemoveMacAI shows it as not applied and you can apply it again.
A macOS update stops partway through its download.
Software Update finishes the update itself, then tries to fetch the Apple Intelligence models the profile blocks and keeps retrying them (#109). After about 2 hours with the Mac awake it gives up on them and installs the update, with the profile still on. Sleep pauses that timer. To skip the wait, run removemacai on, restart, update, then run removemacai off. The restart matters, because the stuck download keeps retrying the old address until then. macOS can start fetching the models again while the profile is off, and removemacai off deletes whatever it got.
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.
Spotlight lost its new look, clipboard history or conversions.
Reports so far point at two settings. In macOS 27 the Spotlight window runs as a process named Siri, so turning Siri off can change it: run removemacai off --keep siri and restart to check. Keeping Siri also keeps the foundation models, about 13 GB. If only web results and conversions are missing, try removemacai undo spotlight-web, which Recommended includes.
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 when Apple Intelligence is off?
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.

Runs since 1.1.0. Most of the testing has been on 27.
15.1 and later (Sequoia)
In testing, use 1.2.0-beta.1. Spatial Photos isn’t on 15, so it’s left out there.
15.0 and earlier
Not supported, Apple Intelligence starts in 15.1
Uninstall
Run removemacai revert or click Undo Everything in the app, then delete the app or run brew uninstall removemacai.
Acknowledgements
The Apple Intelligence part of RemoveMacAI is built on pared, a complete working tool by 4evy that first mapped the asset service, the model sets and several of the settings keys. Its license is in THIRD-PARTY-NOTICES.md.
