Apple Tightens Full-Disk Access to Curb AI Agent Abuse After Meta Muse Incident
Ars Technica AI · rss · 2026-10-03
Apple is changing macOS full-disk access permissions to stop third-party apps from misusing them to read message histories.
The move follows columnist Jason Aten's revelation that Meta's new general-purpose AI agent Muse sent him an unsolicited notification referencing a private Apple Messages thread — though he never granted permission. The incident fueled widespread concern that AI assistants with access to calendars, email, and messages are like power tools: useful but dangerous.
Meta CTO David Singleton rebutted that Muse requires two manually-granted privileges: macOS full-disk access and a Messages connector setting inside Muse.
