Apple to require "very explicit user action" for macOS Full Disk Access amid AI agent privacy concerns

What happened: On 2 October 2026 Apple announced new controls on macOS Full Disk Access, the permission that lets an app read deep into a user's stored data (files, Mail, Messages, browsing history). Granting the permission will now require "very explicit user action", and Apple framed the change explicitly around the risks of increasingly capable autonomous AI agents. The move followed complaints from columnist Jason Aten that Meta's Muse AI agent synced roughly 187,000 rows of his private iMessages database on his Mac even though he believed he had not granted permission; Meta disputes this, saying Messages access is entirely opt-in and requires both Full Disk Access and a separate Messages connector.

Why it matters to creators: Full Disk Access is the gate through which AI agents on macOS can reach a creator's entire local work product - manuscripts, project files, contracts, correspondence with editors and collaborators. Apple's change is a platform-level consent guardrail: AI agents will have to win a deliberate, explicit grant of this broad access instead of relying on a once-granted, forgotten permission. It also signals how platform owners are positioning themselves as gatekeepers for AI agents accessing creative work stored on their devices.

Not yet known: Which macOS version the new controls will ship in and on what timeline; whether the "very explicit user action" requirement blocks previously granted Full Disk Access permissions or applies only to new grants; and whether Meta will change Muse's onboarding flow in response.
