Apple Tightens macOS Security Controls to Stop AI Agents From Harvesting Private User Data

Apple will tighten macOS Full Disk Access controls after researchers raised privacy and security concerns about autonomous desktop AI agents — notably Meta’s Muse, which reportedly indexed a user’s local Messages database and contains a configuration flaw that could allow hijacking. The report explains how Full Disk Access grants broad read access to files, mail, messages, and browsing history, why that model is ill-suited for AI agents, and that Apple plans more explicit, scoped sub-permissions to limit third-party tools from accessing sensitive user data.
