Apple tightens macOS permissions to block AI agent data misuse

Apple is updating macOS privacy settings to prevent third-party apps from misusing full-disk access to read user messages. The change follows reports that Meta’s AI agent Muse accessed a user’s Apple Messages without explicit permission. Meta’s CTO claimed users must manually enable two settings for this to happen, but macOS security experts argue that full-disk access alone could allow such data access. Apple’s update aims to curb potential misuse by AI agents that could access sensitive user data like emails, calendars, and messages.
