In the second beta of macOS 15.4, released earlier in March, Apple changed system settings to hide the local storage space occupied by Apple Intelligence on Macs. The change comes amid accusations that Apple is trying to hide the size of its footprint, so in the fourth macOS 15.4 beta released today, the system is once again making Apple Intelligence's storage requirements easy to find.
To check the storage space of Apple Intelligence, you can go into System Settings > General > Storage and click the Information button next to the macOS list. This will bring up a popup showing the installed version of macOS and the storage space occupied by Apple Intelligence, which is the same way system settings work in the current macOS Sequoia 15.3.2 release.
The lack of Apple Intelligence storage functionality in early macOS 15.4 betas may be a bug. Users who have disabled System Integrity Protection (SIP) can see this information without issue, while Apple appears to be preventing users with SIP from using Apple Intelligence to store assets.
For reference, SIP protects your Mac by preventing unauthorized code from running, and it can only be turned off in recovery mode. Disabling SIP is usually only used by developers testing applications, while most users always leave it on. This may be an unintentional move, given that Apple returns the Apple Intelligence storage space list to all users, but it's unclear at this time.
Apple says Apple Intelligence can take up up to 7GB of storage on a Mac, but with macOS Sequoia 15.4 it appears to take up more space on some Macs. Apple Intelligence requires dedicated storage because it downloads machine learning models and assets to the device in order to run certain features locally.
Disabling AppleIntelligence is the only way to prevent this feature from taking up space on your Mac.
