Days after a journalist claimed that Meta’s Muse app on Mac read their private messages — a claim that Meta disputed — Apple announced that it’s introducing additional controls around a setting called “Full Disk Access” on macOS.

Apple said some developers are using Full Disk Access in ways that could put users at risk, exposing everything on their systems—including files, mail, messages, and even browsing history—without users’ full knowledge and understanding.

Going forward, Apple will introduce additional controls to ensure that users who genuinely wish to grant an app this extraordinary level of access can only do so with very explicit user action. As AI agents become increasingly capable and autonomous, the risks associated with this level of access will grow substantially.

Apple did not say when the new Full Disk Access controls will be implemented.
