Apple is changing macOS controls to make AI-agent access to Mac data more explicit. The company says some applications have used Full Disk Access in ways that could expose files, email, messages and browsing history without users fully understanding the implications. Apple plans new controls requiring more explicit user action before granting this level of access, as it assesses the growing privacy and security risks associated with increasingly capable autonomous AI agents. The move comes amid debate over how AI tools access sensitive Mac data, with Meta disputing claims that its Muse agent could access private messages without users enabling the required permissions.
