Apple tightens Mac Full Disk Access over AI agent risks

Apple says it will add new controls so that granting an app Full Disk Access requires very explicit user action. It cited the risk that increasingly capable AI agents pose to files, messages, mail and browsing history. The change follows a report that Meta's Muse seemed to know the contents of a user's messages, which Meta says is opt-in.

Why it matters: This is a platform owner changing OS-level security because of AI agents, not just warning about them. How operating systems gate agent access to personal data will shape what Mac-based agents like Meta's Muse can do, and it sets a precedent other platforms may follow.
