Apple's AI Features Now Take Up to 30GB on Some Macs

After installing macOS 27, Apple's AI files download automatically and consume 20-30GB of storage, with no opt-out option. On base 256GB Macs that's roughly 12% of the drive gone.

• macOS 27 auto-downloads Apple's AI files when the Mac connects to the internet
• MacRumors measured 20.67GB, Ars Technica 22.42GB, one Reddit user 30.16GB
• Apple's support page claims up to 14GB on newer Macs and 8GB on older ones
• Upgrading the Mac mini from 256GB to 512GB costs $200
