Open-source tool RemoveMacAI deletes Apple Intelligence models from macOS 27 after Apple drops the off switch
macOS 27 no longer offers a single Apple Intelligence toggle and keeps on-device models installed. RemoveMacAI, a free MIT-licensed command-line tool, disables the features, deletes the models and blocks re-downloads; its developer claims roughly 12GB reclaimed, not yet independently tested.
AT Pulse research deskOctober 6, 2026 · 5 min read · AI-assisted analysismacOS 27 removed the master Apple Intelligence toggle that macOS Tahoe had. Local models now stay on disk even when every AI feature is off, and turning the features off means going through about a dozen settings. User reports put Apple Intelligence storage between 14GB and more than 30GB, which is above Apple's stated figure of up to 14GB. Apple has not explained the gap. [1] [2] [3] [8]
RemoveMacAI uses a configuration profile to apply Apple's own restriction keys and to force the settings that have no key. It then removes the models through Apple's asset service while System Integrity Protection stays on. To block re-downloads, it sends each model's download to a closed local port. Users can preview and undo changes with the dry-run, status and revert commands. [6] [7]
The tool has real costs. It disables Siri, Writing Tools, Genmoji and Xcode code completion, and it breaks third-party apps built on Apple's Foundation Models framework. Some of the keys it relies on were deprecated in macOS 26.4. The developer says the changes survive updates, but MacBreeze expects future macOS updates to reinstall the components. [2] [4] [6] [7]
User reports show Apple's on-device models can take up far more storage than Apple's guidance, and macOS 27 has no built-in way to remove them. As a result, IT teams and app developers may need to plan for Macs that have no local models.
Executive brief
macOS 27 has no single switch to turn off Apple Intelligence, and the on-device models stay on disk even when every AI feature is disabled. A free, MIT-licensed command-line tool called RemoveMacAI turns the features off, deletes the models and stops macOS from downloading them again. The developer says this frees about 12GB (The Verge). A Verge writer's MacBook Air listed Apple Intelligence at 35.05GB. Apple's support document says "up to 14GB." No independent test of the tool has been published, and Apple has not commented.
What changed and event timeline
Off switch reported gone
MacBreeze reported that macOS 27 "Golden Gate" dropped the master Apple Intelligence toggle that macOS Tahoe had, and that local models now stay installed ().
Storage exceeds Apple's guidance
MacRumors collected user reports of 14GB to 30.16GB of Apple Intelligence storage across M1 to M4 Pro Macs. Apple's stated figure is up to 14GB, and Apple has not explained the gap ().
RemoveMacAI surfaces
The developer posted the tool on Reddit. MacRumors and The Verge covered it the same day. MacRumors reported hundreds of GitHub stars within a week (,).
Follow-up how-to
MacRumors published usage steps and cited user reports of reclaiming more than 20GB. It also stressed that the tool has no connection to Apple ().
Capabilities and access
- Target: Apple silicon Macs running macOS 27. The README says it was tested on 27.0 and 27.0.1 and does not support earlier versions (GitHub README).
- Commands:
removemacai,status(shows size per model),off --dry-run,revertandfeatures(GitHub). - What it disables: Siri and "Hey Siri", Writing Tools, Genmoji, Image Playground, the ChatGPT extension, summaries, smart replies, text predictions, Photos Clean Up, Spatial Photos and Xcode code completion.

Dictation keeps working (Cult of Mac).
- Install and licence: a curl one-liner or Homebrew; MIT licence.
Technical analysis for researchers and developers
- How it works: a configuration profile applies Apple's own restriction keys and forces the settings that have no restriction key.
- Blocking re-downloads: the profile sends each model's download to a closed local port, so the fetch simply fails (Cult of Mac).
- Effect on developers: third-party apps built on Apple's Foundation Models framework stop working. In macOS 27, Spotlight runs as a process named "Siri" (GitHub).

- Blocking re-downloads: the profile sends each model's download to a closed local port, so the fetch simply fails (Cult of Mac).
- Effect on developers: third-party apps built on Apple's Foundation Models framework stop working. System Settings may keep counting the models until macOS schedules their deletion. In macOS 27, Spotlight runs as a process named "Siri" (GitHub).
- Reproducibility: the dry-run and status commands let users check what changes. There is no published benchmark of space reclaimed.

| Claim | Source | Status |
| About 12GB freed | Developer, via The Verge | Developer-reported |
| Changes survive macOS updates | GitHub | Developer-reported; not independently tested |
| Some users reclaim more than 20GB | MacRumors | User anecdotes |
| 35.05GB shown on one MacBook Air | The Verge | Reporter's observation of storage, not a test of the tool |
| "Up to 14GB" required | Apple, via MacRumors | Vendor figure |
No independent hands-on evaluation of the tool's removal or persistence claims was found.
Context and prior work
- macOS Tahoe had a single toggle that turned off the AI features and deleted the local models (MacBreeze).
- In macOS 27, turning features off means visiting about a dozen settings, several of them under Screen Time (The Verge, Digital Trends).
- RemoveMacAI restores what the old toggle did as a scripted, reversible step.
Limitations, safety and contested findings
- Deprecated keys: some restriction keys the tool depends on were deprecated in macOS 26.4.
- Persistence is disputed: the developer says changes survive updates. MacBreeze says future updates are expected to reinstall the components (MacBreeze).
- Unclear storage figures: Apple has not explained why some Macs show far more storage than its stated requirement.

- Deprecated keys: some restriction keys the tool depends on were deprecated in macOS 26.4. They still work in 27.0.1, but a future update could break the tool (MacRumors).
- Persistence is disputed: the developer says changes survive updates. MacBreeze says future updates are expected to reinstall the components (MacBreeze).
- Unclear storage figures: Apple has not explained why some Macs show far more storage than its stated requirement.
- No endorsement: MacRumors states it does not endorse the tool and that users run it at their own risk (MacRumors).
Business and practitioner implications
- IT teams: the tool uses configuration-profile restriction keys, which are the same kind MDM systems use, so managed fleets can likely apply similar policies centrally.
- App developers: if your app relies on the Foundation Models framework, plan for users and fleets where the on-device model is missing.
- Storage costs: base-storage Macs can lose 14GB to 30GB+ to models, which makes storage upgrades or a removal policy part of the purchase decision.

- Apple: removing the opt-out has produced a community workaround and bad press. That is a reputational risk for an AI strategy built on features users can't turn off.
