Apple is tightening macOS Full Disk Access controls, saying autonomous AI agents make broad file, mail, and message access too dangerous to leave unchecked.
Apple confirmed it will add new permission controls around macOS's Full Disk Access setting, explicitly citing the growing capability of AI agents as the reason. The company says agents with FDA today can read files, messages, mail, and browsing history with little friction, a risk profile it now considers unacceptable.
The move lands directly on competitors: Meta has pushed back, arguing FDA restrictions aren't sufficient to stop its Muse agent from reading messages the way it wants. Apple is proceeding regardless, rolling out the changes as a platform-level guardrail rather than waiting for developer consensus.
This is the first major platform owner drawing a hard line on agent permissions, and it sets precedent other OS vendors will face pressure to match. Any company shipping an agent product on macOS now needs to rearchitect around tighter access, adding friction and cost to agent rollouts industry-wide.
