An Open-Source Tool Lets You Delete 12GB of Apple Intelligence Data on macOS
Apple Intelligence is becoming a bigger part of the Mac experience, but not every Mac user wants to use Apple's AI features. Now, an open-source tool called RemoveMacAI is giving those users another option: turn off Apple Intelligence, remove its downloaded AI models, and reclaim roughly 12GB of storage on supported Macs.
The tool has appeared at an interesting time. With macOS 27, Apple no longer provides a single master switch for completely disabling Apple Intelligence. Users can turn off individual AI features, but the underlying models can remain stored on the Mac. RemoveMacAI is designed to handle the process more comprehensively.
For people using Macs with smaller SSDs, recovering even 10GB or more can be meaningful. But there is an important trade-off: removing the models also means giving up many Apple Intelligence features.
What is RemoveMacAI?
RemoveMacAI is an open-source command-line utility created by developer Om Lahore. Its purpose is straightforward: disable Apple Intelligence on macOS 27, remove the downloaded models from the Mac, and prevent macOS from immediately downloading those models again.
The project is released under the MIT license and is available publicly on GitHub.
Unlike a traditional Mac cleaning application, RemoveMacAI isn't simply searching for random large files and deleting them. According to its documentation, it uses Apple's own configuration and asset-management mechanisms to disable the relevant features and remove the downloaded models.
The project says it does not require users to disable System Integrity Protection (SIP) and does not directly modify files inside /System.
That distinction is important because manually deleting protected macOS components can create unnecessary risks.
Why does Apple Intelligence take so much storage?
One of the major differences between Apple Intelligence and a simple cloud-based chatbot is that some Apple Intelligence capabilities use on-device models.
Apple says Apple Intelligence can require up to 14GB of storage on compatible Macs with M3 or later chips and at least 12GB of unified memory. Other compatible devices can require up to 8GB.
Those models allow certain AI capabilities to run locally on the device rather than sending every operation to a remote server.
That approach has advantages. It can improve privacy, responsiveness and availability for some tasks.
But there is also a cost: local AI models occupy storage space.
For someone with a 256GB SSD, losing around 12GB—or potentially more depending on configuration—can be noticeable.
The problem with macOS 27
The controversy isn't simply about the size of the AI models.
The bigger issue is user control.
According to the RemoveMacAI project and recent reports, macOS 27 removed the previous single switch for completely turning off Apple Intelligence. Instead, users may have to manage individual AI features in different places. Even after disabling features, the downloaded models can remain on the Mac.
That creates an unusual situation:
You can decide that you don't want Apple Intelligence, disable features, and still have the AI models occupying storage.
That's the problem RemoveMacAI is attempting to solve.
What does the tool actually remove?
RemoveMacAI can disable a substantial collection of Apple Intelligence functionality.
According to the project's documentation, the tool can turn off features including:
Siri and Siri AI
Writing Tools
Genmoji
Image Playground
ChatGPT integration
Mail summaries
Messages summaries
Safari summaries
Notes summaries
Notification summaries
Mail smart replies
Inline text predictions
Spatial Photos
Photos Clean Up
Xcode predictive code completion
It also removes corresponding Apple Intelligence models, including foundation models and models used for image generation, Genmoji, Spatial Photos, Photos Clean Up and Xcode code completion.
So this isn't simply a storage-cleaning trick.
It effectively removes much of the Apple Intelligence experience from the Mac.
How much space can you get back?
The headline figure is approximately 12GB, but users shouldn't assume that every Mac will recover exactly 12GB.
Apple's own documentation says Apple Intelligence can use up to 14GB on certain newer Macs, while the actual storage footprint can vary.
RemoveMacAI includes a status command that can show the models and their sizes before making changes. That gives users a better idea of what they can potentially recover.
Some reports have also described larger Apple Intelligence storage footprints in certain configurations.
So the sensible approach is:
Check your Mac first rather than assuming you'll get exactly 12GB back.
Does RemoveMacAI delete personal information?
This is an important distinction.
The tool is primarily designed to remove Apple Intelligence models and disable AI features. The widely reported 12GB figure is therefore better described as AI model storage rather than a collection of personal documents, photos or messages.
The project's documentation also states that RemoveMacAI makes no network requests and collects no data.
However, users should still treat any third-party command-line utility with caution.
Open-source does not automatically mean risk-free.
Before installing a tool that changes system configuration, users should review the project's source code, releases and documentation and make sure they understand what will happen.
What happens to Siri?
Siri is one of the major features affected.
RemoveMacAI disables Siri-related Apple Intelligence functionality as part of its process. However, the developer specifically notes that Dictation remains available, because its speech models are separate from the Apple Intelligence models being removed.
That's useful for people who still want voice dictation but don't want Apple's broader AI features.
What about Photos Clean Up and other features?
This is where Mac users need to think carefully before removing Apple Intelligence.
If you use features such as Photos Clean Up, Writing Tools, Genmoji, AI-powered summaries or other Apple Intelligence functionality, removing the models means those capabilities won't be available.
Apple has been integrating Intelligence across more parts of macOS. Its current Mac documentation describes Apple Intelligence features across apps and experiences, including Siri AI, writing assistance and organization tools.
Therefore, removing the models makes the most sense for someone who has consciously decided:
"I don't use these features, and I would rather have the storage space."
It makes less sense for someone who regularly uses Apple Intelligence.
Is it reversible?
One of the more useful aspects of RemoveMacAI is that the process is designed to be reversible.
The project provides a revert command that removes the configuration changes. Once the restrictions are removed, macOS can download the required models again when Apple Intelligence features are needed.
That means users aren't permanently modifying their Mac into an AI-free machine.
They are essentially choosing to remove the current AI models and prevent them from returning until they reverse the changes.
Who should consider using it?
RemoveMacAI could be particularly interesting for several groups.
Mac users with small SSDs
Someone with a 256GB Mac may value every gigabyte of available storage.
If Apple Intelligence is using around 12GB and the user never uses it, reclaiming that space could be worthwhile.
Users who don't want AI features
Not everyone wants AI integrated into every part of their operating system.
Some users simply prefer a traditional Mac experience without AI-generated summaries, writing assistance or image-generation tools.
Developers and technical users
Because RemoveMacAI is a command-line tool, it is naturally more suitable for people who are comfortable using Terminal and reviewing configuration changes.
Who probably shouldn't use it?
If you regularly use Apple Intelligence, removing it doesn't make much sense.
You could lose access to features that you actually find useful, only to recover storage that you may not urgently need.
It is also not a good idea to install the tool blindly just because a headline says "Get 12GB back."
The storage benefit needs to be weighed against the functionality being removed.
Is it available for every Mac?
No.
The project's current documentation lists Apple silicon Macs running macOS 27 as supported. It specifically lists macOS 27.0 as supported and notes that macOS 27.0.1 requires RemoveMacAI 0.2.3 or later. Macs running macOS 26 or earlier are not supported by the project.
So before doing anything, users should check:
Mac → About This Mac
and confirm their processor and macOS version.
What about future macOS updates?
Another interesting aspect is persistence.
RemoveMacAI says its configuration profile and download-blocking settings persist across macOS updates. However, that doesn't mean the tool is guaranteed to work forever.
Apple can change system configuration keys, asset-management behavior or security mechanisms in future versions of macOS.
In fact, the project's own documentation and recent coverage highlight that Apple has already changed some of these mechanisms between macOS releases.
Therefore, anyone using the tool should check its GitHub documentation after major macOS updates.
Apple's AI storage strategy raises a bigger question
The RemoveMacAI story isn't just about getting 12GB of storage back.
It highlights a larger question about the future of operating systems.
As companies move more AI processing onto personal devices, local AI models are becoming another type of software that consumes storage.
Traditional operating systems already use storage for apps, system files, caches and updates.
Now AI models are becoming another significant category.
For users with large SSDs, this may not matter much.
For people with smaller drives, however, the difference between a 256GB and 512GB Mac can make AI model storage much more noticeable.
The bigger debate: choice versus convenience
Apple's approach has a clear advantage: Apple Intelligence is integrated into the operating system and can work across multiple apps.
But RemoveMacAI's popularity shows that some users want another choice.
They don't necessarily want to disable every Apple feature.
They simply want the ability to say:
"I don't use Apple Intelligence. Don't keep its models on my computer."
That's a reasonable debate as AI becomes more deeply embedded into operating systems.
A simple system-level switch to disable Apple Intelligence and remove its downloaded models would give users a straightforward official option.
Until then, third-party projects such as RemoveMacAI are filling that gap for technically confident Mac users.
Should you remove Apple Intelligence from your Mac?
For most users, there's no urgent reason to remove it.
If you use Apple Intelligence features, the storage is part of what makes those capabilities possible.
But if you're running out of disk space, never use Apple Intelligence and have a supported Apple-silicon Mac running macOS 27, RemoveMacAI offers an interesting way to reclaim storage.
Just remember that 12GB isn't free money.
You're trading storage for functionality.
Before using any third-party system tool, check the project's documentation, verify that your Mac and macOS version are supported, understand which features will stop working, and keep a current backup.
The bigger story is perhaps not that a developer found a way to delete 12GB of AI models.
It's that AI is now large enough to become a storage-management issue on everyday computers.
As Apple, Microsoft, Google and other technology companies push more AI onto devices, local AI models could become as normal—and as noticeable—as traditional applications.
For Mac users, the question may increasingly become not just "What can AI do for me?"
but also:
"How much of my computer do I want AI to occupy?"
