A new open-source tool lets Mac users remove Apple Intelligence from macOS 27 and regain 12GB of storage or more. Named RemoveMacAI, the tool runs from Terminal.

Apple took away the Apple Intelligence master switch in macOS 27. Now, if you turn off individual features, the AI models still sit on your drive. On a Mac with a small SSD, that’s a lot of dead weight.

How to remove Apple Intelligence with RemoveMacAI

Apple Intelligence takes up gigabytes of storage on a Mac because many of its AI models run locally rather than sending everything to Apple’s servers. This helps protect users’ privacy while speeding up tasks.

macOS stores these models on the Mac so features such as Writing Tools, Image Playground, etc., can work without constantly uploading your data to the cloud. But, understandably, anyone not interested in macOS 27’s AI capabilities might want those gigabytes of storage back. And RemoveMacAI does the job.

It’s free and is available on GitHub under the MIT license. It requires macOS 27 and a Mac with Apple silicon. You can either install it with one-line curl command or through Homebrew.

Once launched, the tool displays the current state and asks you to confirm. It then opens System Settings so you can approve a configuration profile. macOS requires you to do that, so the tool can’t skip it. After that, the tool removes the models from your drive.

If you want to play it safe, run the dry-run option first. Doing so shows the changes without applying them. You can also tell RemoveMacAI to leave certain features switched on, with a reverse command undoing everything.

What RemoveMacAI changes under the hood

The configuration profile applies Apple’s own restriction keys for Apple Intelligence. The AI models are then removed using Apple’s asset service. But System Integrity Protection stays on, so nothing under /System is edited directly.

To keep the models from coming back, the profile sends each model’s download to a closed local port. That way, the fetch simply fails. The developer claims the profile persists across macOS updates, with the tool making no network requests and collecting no data.

What stops working after the cleanup

If you remove Apple Intelligence, a lot of features stop working. Siri goes away, and so does the “Hey Siri” wake word. Writing Tools, Genmoji and Image Playground also vanish. So do the ChatGPT extension and summaries in Mail, Messages, Safari, Notes and notifications.

Mail smart replies, inline text predictions, Spatial Photos and Photos Clean Up also stop working. The same goes for predictive code completion in Xcode. Apps that make use of Apple’s on-device models, like the Use Model action Shortcuts, also go away. Visual Intelligence and natural-language editing in Calendar disappear as well. But Dictation still works, since it uses a separate setting.

How much space you get back

The developer says using RemoveMacAI will restore around 12GB of storage. That sits right within Apple’s own range. Apple lists up to 14GB of Macs with M3 or newer and at least 12GB of memory.

Some Macs show far more in System Settings. Some users have reported reading above 30GB on macOS 27. Apple’s own support page doesn’t explain why some machines report larger figures.

If you run RemoveMacAI, don’t panic if System Settings still shows the old number for a while. The developer says macOS deletes the files on its own schedule, meaning the storage readout might lag.

Risks to weigh before you run RemoveMacAI

This is a third-party script that changes system settings. Read the code first, and use the dry-run option to be on the safer side. Also remember that you’re trusting a stranger’s repo.

Then there’s the durability catch. The developer reportedly warns that some restriction keys the tool relies on were deprecated in macOS 26.4. They might still work in macOS 27.0.1, but a future update could change that.

If you never touch Apple Intelligence, it’s definitely tempting to remove all those stored models from your Mac. However, if you lean on Siri or Writing Tools, think twice.
