New full-disk-access controls on macOS target the exact permissions that let AI agents like Meta's Muse read user files and messages.
Apple is rolling out new restrictions on full disk access for Mac, explicitly citing the 'substantial' increase in risk posed by AI agents operating on the system. The change directly follows reporting that Meta's Muse agent relies on broad disk permissions to function across apps.
Meta has pushed back, arguing current full-disk-access controls aren't sufficient context for what Muse actually needs. Apple's move effectively forces third-party agent makers to work within tighter, Apple-defined permission boundaries.
Platform owners are starting to gatekeep agent access at the OS level, not just the API level. Any company building consumer AI agents needs a permissions strategy that survives Apple and Google tightening the rails underneath them.
