Apple Tightens macOS Full Disk Access to Curb AI Risks

Apple Inc. announced on October 2, 2026, that it will implement additional controls for the Full Disk Access permission on macOS. The company is requiring more explicit user action before granting this level of access to ensure users understand the risks to private data, including mail, messages, browsing history, and files.

While the feature was originally designed for backup applications, Apple stated that some developers are using it in ways that jeopardize privacy. The company specifically noted that the risks associated with broad system access grow substantially as AI agents become more capable and autonomous.

This policy shift follows reports of security flaws in the ChatGPT Mac app and allegations that Meta Platforms Incorporated accessed private messages via its Muse app without explicit permission. Meta has disputed those claims.
