Apple Intelligence Storage Is Ballooning on macOS 27
If you’ve installed macOS 27 Golden Gate, you may have noticed something unexpected: Apple Intelligence storage is eating up far more space than Apple’s own support documents suggest. On some Macs, the on-device AI models are consuming well over 30GB — and unlike previous versions of macOS, you can’t opt out.
After installation, Apple automatically downloads a multi-gigabyte AI model to your Mac the next time it connects to the internet. Siri AI, and by extension Apple Intelligence, are now a mandatory part of the system.
What Apple Says vs. What Users Are Seeing
Apple’s official guidance states that the latest Apple Intelligence features require up to 14GB of on-device storage on Macs with an M3 chip or later and at least 12GB of unified memory. For other Apple Intelligence-enabled Macs, Apple lists a requirement of up to 8GB.
But real-world reports tell a different story.
An M4 Pro Mac mini running macOS 27 showed 20.67GB allocated to Apple Intelligence in System Settings.
A fresh installation of macOS 27.0 beta 7 on an M3 MacBook Air recorded 22.42GB.
One user shared a screenshot from the macOS 27 Release Candidate showing Apple Intelligence consuming 30.16GB.
Another user reported 24.35GB on a MacBook Pro with an M3 Pro chip.
Both the M4 Pro Mac mini and M3 MacBook Air use Apple’s AFM 3 Core Advanced on-device model, which requires an M3-or-newer Mac with 12GB or more of RAM. That explains the higher figures on those machines — but not the unusually large allocations on older hardware.
Older Macs Are Also Losing More Space Than Expected
Macs that don’t meet the minimum requirements for Apple’s most advanced model are still losing significant storage. An M1 MacBook Air and a MacBook Neo each showed around 14GB — devices that fall into the category where Apple lists a requirement of up to 8GB.
Apple’s Official Storage Requirements
| Device | Apple Intelligence Storage |
|---|---|
| iPhone 18 Pro, iPhone 18 Pro Max, iPhone Duo | Up to 14GB |
| iPhone 17 Pro, iPhone 17 Pro Max, iPhone Air | Up to 14GB |
| Other compatible iPhones: iPhone 15 Pro and Pro Max, all iPhone 16 models, iPhone 17, and iPhone 17e | Up to 8GB |
| iPad with M4 or later and at least 12GB of unified memory; Mac with M3 or later and at least 12GB of unified memory; Apple Vision Pro (M5) | Up to 14GB |
| Other compatible iPad, Mac, and Apple Vision Pro models | Up to 8GB |
| Compatible Apple Watch models | Up to 1.5GB on the watch |
| iPhone 15 and 15 Plus, iPhone 14 and earlier, and iPhone SE | Not supported |
Figures taken from Apple’s support document.
Apple’s support document does not explain whether its “up to 14GB” requirement is directly comparable with the Apple Intelligence “Storage” category in System Settings, or why some Macs display substantially higher numbers. Notably, the same ballooning figures have not been observed on iPhones and iPads running iOS 27 and iPadOS 27.
Why This Matters for Mac Users
This isn’t just an academic concern. While using Apple Intelligence is optional, downloading its on-device models is not. In macOS 27 and iOS 27, Apple removed the toggle to disable Apple Intelligence entirely. Users must set aside space for Apple’s models whether they plan to use the features or not.
The timing is particularly frustrating. Memory and storage costs are rising across the industry because of AI demand, and Mac users are now forced to allocate a growing share of their fixed internal storage to AI models they may never use.
For anyone running a base-model Mac with 256GB or 512GB of storage, losing 20GB to 30GB to Apple Intelligence represents a meaningful chunk of available space — space that can’t be reclaimed through any official setting.
How to Check Your Own Apple Intelligence Storage
If you’re on a Mac, you can see how much space Apple Intelligence is using:
Open System Settings.
Go to General.
Click Storage.
Click the information button beside macOS.
This will show you the Apple Intelligence storage category and how much space it’s consuming on your machine. The figure may be higher than you expect, especially if you’re running macOS 27 on an M3-or-newer Mac.
Community Reaction
The removal of the Apple Intelligence toggle has drawn sharp criticism. Many users argue that opting out should be the default, not the exception — particularly given Apple’s premium storage pricing.
One commenter noted that being able to turn Apple Intelligence off was arguably its best feature. Another pointed out that with growing backlash against AI in general, Apple’s decision to make it mandatory seems poorly thought out.
Several users suggested that Apple should provide a single switch to disable all artificial intelligence features — whether or not they carry the Apple Intelligence branding — while continuing to develop those features for people who want them.
What to Do If You’re Concerned About Storage
There’s currently no official way to prevent the Apple Intelligence model download or reclaim the storage it uses on macOS 27. If storage is a critical concern for your workflow, your main options are:
Check your current usage in System Settings to understand exactly how much space Apple Intelligence is consuming.
Consider external storage for large files, projects, and media libraries if you’re running low on internal space.
Stay informed about macOS updates, as Apple may adjust storage requirements or reintroduce opt-out options in future releases.
For now, the situation remains unresolved. Apple has not publicly addressed why some Macs show substantially higher Apple Intelligence storage figures than its own documentation states.
