Some Mac users running macOS 27 are reporting that Apple Intelligence takes far more storage than Apple’s published requirement suggests. Reports of 20GB or more, including some above 30GB, should be treated as user-reported measurements rather than a confirmed system-wide macOS issue.
Apple’s Apple Intelligence requirements say that certain supported Macs can require up to 14GB of on-device storage, while other compatible Macs can require up to 8GB. Apple does not explain on that page why the Storage panel may show a larger Apple Intelligence category on particular machines.
That difference matters most on Macs with 256GB SSDs, where a few extra gigabytes can noticeably reduce room for apps, projects and local media. It does not by itself prove that every Mac has downloaded the same model or that the reported figure is permanent.

Check the figure before assuming a problem
Mac users can review storage in System Settings by opening General, selecting Storage and inspecting the categories shown there. A reading higher than Apple’s published requirement is useful information, but Apple has not published a troubleshooting document that identifies a single cause or a universal fix.
Users should avoid deleting system files or using unsupported commands to reclaim space. That can damage a macOS installation or simply trigger another download. The safer response is to make a current backup, note the figure and look for future macOS updates or Apple guidance.
For now, the careful conclusion is that Apple’s official storage estimate and some reported Storage-panel readings do not line up. Apple has not confirmed whether those readings represent an error, additional models, caches or another category of system data.
