Apple Intelligence is taking up considerably more storage than Apple advertises on some Macs running macOS 27, with reported footprints exceeding 20GB and, in some cases, 30GB.
Apple’s support documentation says Apple Intelligence requires up to 14GB of storage on certain compatible Macs and up to 8GB on others.
But Mac owners checking the Storage panel in System Settings are finding much larger numbers assigned to Apple Intelligence.
Apple hasn’t explained what’s behind the difference or whether the additional space consists of AI models, cached files, or data macOS is categorizing under the same label.
The reports don’t appear to affect every Mac equally, and storage usage can vary considerably between machines.
30GB is a lot on a 256GB Mac
Losing an unexpected 10GB or 20GB probably won’t matter much if your Mac has a terabyte of storage. It’s considerably harder to ignore on a 256GB model.
A 30GB Apple Intelligence footprint alone would consume nearly 12% of a 256GB drive before accounting for macOS, apps, photos, documents, and everything else stored locally.
That’s particularly relevant because Apple still sells several Macs with 256GB as their entry-level storage configuration.
However, there are reasons to be cautious about the numbers. The larger figures come from individual Macs rather than a confirmed issue affecting every Apple Intelligence-compatible machine.
It’s also unclear whether the Storage panel is measuring only the AI models themselves. Some of the additional space could be temporary data, caches, or other files that macOS groups under Apple Intelligence.
Until Apple explains how it calculates that figure, a Mac showing 30GB under Apple Intelligence doesn’t necessarily mean 30GB of permanent AI models have been downloaded.
You can check how much it’s using
Open System Settings > General > Storage and look for Apple Intelligence in the list of storage categories.
If yours is considerably higher than Apple’s published figures, there isn’t currently an official method specifically intended to shrink the Apple Intelligence storage footprint.
Manually deleting system files isn’t a good workaround. macOS may need those files to run Apple Intelligence, and removing them could cause problems or simply trigger the same downloads again.
For anyone running short on storage, the more useful question will be whether macOS eventually reclaims some of that space automatically. Apple hasn’t documented that behavior or explained why some Macs are showing Apple Intelligence storage well above its published requirements.
