On October 5, 2026, MacRumors and The Verge reported on RemoveMacAI, a free, open-source command-line tool for Macs running macOS 27. It turns off Apple Intelligence and deletes the AI model files it downloads. Both outlets say this frees roughly 10–12 GB of storage. Is it safe? It reportedly uses a gentler method than deleting system files by hand, and you don’t have to disable System Integrity Protection. But it’s unofficial. Apple doesn’t endorse it, and a future macOS update could break it.
If you’ve been trying to delete Apple Intelligence data on your Mac to win back disk space, this covers what’s confirmed, what isn’t, and whether it’s worth it. All sources below were retrieved on October 5, 2026.
What Happened
macOS 27 dropped the single Apple Intelligence off switch
According to the MacRumors and The Verge reports, Apple removed the one master on/off switch for Apple Intelligence in macOS 27. Digital Trends reported the same change.
You can still turn off individual features in System Settings > Apple Intelligence & Siri, such as Writing Tools or Genmoji. That stops you from using those features. Per the reports, it doesn’t delete the AI model files sitting on your drive.
Why did Apple remove the switch? Apple hasn’t published a Newsroom post, Support article, or developer note explaining it. Anything beyond that is guesswork, so we won’t guess.
Does turning off features in Settings free up storage?
No, according to the reports. That’s the main problem RemoveMacAI is meant to solve. Even with every feature switched off, the downloaded models reportedly stay on disk.
How big are those files? Estimates vary by source and Mac:
- MacRumors and The Verge report RemoveMacAI reclaims about 10–12 GB.
- AppleInsider headlines a 12 GB saving.
- An earlier MacRumors report from September 23, 2026, says Apple Intelligence can use up to 30 GB on some Macs running macOS 27.
None of these figures come from Apple. They’re media and developer claims. Your number could be higher or lower.
What RemoveMacAI reportedly does
Per MacRumors, The Verge, and the project’s GitHub page, RemoveMacAI:
- Installs a configuration profile. It’s the same kind of settings file companies and schools use to manage Macs. It applies Apple’s restriction keys to turn Apple Intelligence off. The tool shows your current state and asks for confirmation first, then opens System Settings, where you have to approve the profile yourself.
- Uses Apple’s own asset service to remove the models. It asks macOS to remove the model files instead of deleting them directly.
- Blocks automatic re-downloads. The profile redirects the download of each removed model to a closed local port, so macOS can’t quietly fetch it again.
The developer says the profile, including the download block, persists across macOS updates, and that Dictation keeps working because its speech models aren’t removed.
What it reportedly doesn’t do matters just as much. It doesn’t ask you to turn off System Integrity Protection (SIP), the macOS feature that stops apps and users from changing core system files. And it doesn’t delete protected files by hand. The reports call this safer than manual deletion. That’s a big deal, because a MacRumors forum thread warns that deleting Apple Intelligence files yourself risks operating-system problems.
The Verge, citing a Reddit discussion, says the developer built the tool to recreate what the old single switch did.
What you’ll lose
By default, RemoveMacAI turns everything off. According to its documentation, that includes:
- 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
- Photos Clean Up
- Spatial Photos
- Xcode predictive code completion
Apps that use Apple’s on-device models, Visual Intelligence, and natural-language editing in Calendar stop working too.
You don’t have to give up everything, though. The tool’s --keep option leaves named features alone. For example, this keeps the Photos features while turning off the rest:
removemacai off --keep spatial-photos,photos-clean-upRun removemacai features to see the accepted names, removemacai status to see each feature and how much space its models use, and removemacai off --dry-run to preview the changes without applying them.
Version check: The developer says RemoveMacAI is tested on macOS 27.0, and that on macOS 27.0.1 you need version 0.2.3 or later. The latest release at the time of writing is v0.2.5, published October 5, 2026. You can install it with Homebrew or with the developer’s install script, which downloads the latest release and verifies its checksum.
How to undo it
The reports describe a revert command that removes the restriction profile. That lets macOS download the Apple Intelligence models again:
removemacai revertExpect the models to re-download after you revert. Your storage savings will go away.
Is RemoveMacAI endorsed by Apple?
No. It’s a third-party tool. Apple doesn’t distribute it, recommend it, or document this method. MacRumors also flags a real long-term risk: some of the configuration-profile keys the tool relies on were deprecated in macOS 26.4. Deprecated means Apple has marked them for eventual removal. They still work in macOS 27.0.1, per MacRumors. A future update could still break the tool without warning.
One more caveat: before you run any command-line tool, make sure you’re getting it from the developer’s genuine source.
Who This Affects
- Macs: Apple silicon Macs running macOS 27 or 27.0.1. macOS 27 is the first release that runs only on Apple silicon, so Intel Macs aren’t affected (9to5Mac).
- Storage-squeezed owners: On a 256 GB base-model MacBook Air or Mac mini, 10–12 GB is a real slice of your drive.
- Privacy-minded users: Some people want Apple Intelligence fully off, with nothing left behind. This gets you there, unofficially.
- Comfort level: There’s no reported graphical app. You’ll need to be OK typing commands in Terminal (found in Applications > Utilities).
If you’ve come to the Mac from Windows, Terminal is roughly the Mac’s version of Command Prompt or PowerShell. It’s powerful, so only paste in commands you understand and trust.
How It Stacks Up
We’re sticking to a Mac-only comparison here, since there’s no sourced storage data to line up against Gemini Nano, Galaxy AI, or Copilot+ PCs. Here are your options on the Mac itself:
| Option | Turns off AI features? | Deletes model files? | Blocks re-download? | Official? | Source |
|---|---|---|---|---|---|
| Old single switch (pre-macOS 27) | Yes, in one step | Not confirmed in our sources | Not confirmed in our sources | Yes | The Verge |
| Individual toggles in macOS 27 Settings | Yes, one at a time | No (per reports) | No (per reports) | Yes | MacRumors |
| RemoveMacAI | Yes, all at once or all but the features you keep | Yes, ~10–12 GB reported | Yes | No | MacRumors, The Verge |
| Deleting files by hand | Unclear | Yes | No | No | MacRumors Forums (warns of OS problems) |
The pattern is clear. In macOS 27, switching Apple Intelligence off is harder than it was in macOS 26. Right now, the fix comes from an outside developer.
The Reaction
Coverage so far focuses on the storage savings and the reversible approach. AppleInsider framed it as a way to reclaim about 12 GB, and Help Net Security also covered the release. MacRumors notes that some users reported reclaiming significantly more than 12 GB, which fits the wide range of storage estimates above.
Our read: the interest is about the gap RemoveMacAI fills. A tool whose selling points are “removes the models” and “fully reversible” shows that some users want a real choice about what runs on their own Mac.
Our Take
Verdict: Apple did this worse than before. macOS 27 took away a simple, official control. In its place is a set of toggles that, per the reports, don’t touch the storage those features use. A third-party developer then had to rebuild the missing off switch using deprecated settings. That’s a poor look for Apple.
Should you use RemoveMacAI? It depends on your situation:
- Use it if you’re on a tight drive, you can live without most of the features listed above, and you’re comfortable with Terminal. The reported method is far less risky than deleting files yourself,
--dry-runlets you preview it, and therevertcommand gives you a way back. - Skip it if you depend on most of these features.
--keepcan spare a few, but the more you keep, the less space you’re likely to reclaim. - Wait if you’re not sure. Apple could restore an official switch, or the deprecated keys could break in an update. Neither is confirmed either way.
If you need space but want to keep Apple Intelligence, an external SSD is the low-risk route. Something like the Samsung T7 Shield or SanDisk Extreme Portable SSD can hold your photo library or old projects. On a MacBook with only USB-C ports, a USB-C hub saves you from constantly swapping cables.
What to Do Next
Before you decide anything, check how much space you actually have. Go to System Settings > General > Storage and note your available space. If you’ve got plenty free, the 10–12 GB at stake may not be worth losing features over.
If you do try RemoveMacAI, run removemacai status and check Storage again afterward, since the published figures aren’t Apple benchmarks. Don’t panic if Storage still lists Apple Intelligence right away: the developer says macOS deletes the released files on its own schedule, and Storage keeps counting them until then.
We’d rather Apple just put the switch back.
