Apple tightens Full Disk Access on macOS as AI agents raise risk concerns (Sarah Perez/TechCrunch)

Apple is adding extra controls to macOS Full Disk Access after AI agents increased the risks of that level of access.
Apple announced on 2 October 2026 that it will tighten the “Full Disk Access” permission in macOS, adding new controls that require a more explicit user action before an app can read the entire contents of a Mac’s storage. The move comes after a journalist alleged that Meta’s Muse app on macOS accessed private messages, prompting Apple to flag the growing “risks associated with” autonomous AI agents that can exploit the broad reach of the permission.
Full Disk Access has long been a backdoor for backup utilities and other tools that need unfettered file‑system visibility, bypassing the granular privacy categories Apple otherwise enforces. Apple’s developer note warns that some developers are using the permission in ways that could expose users’ files, messages, mail and browsing history to AI agents capable of processing that data without clear consent.
The change matters because AI‑driven assistants are increasingly embedded in everyday apps, and unrestricted file access could turn a benign utility into a conduit for large‑scale data harvesting. By forcing a more deliberate grant flow, Apple aims to restore a layer of user control and signal that the company will not tolerate “capable, autonomous AI agents” that operate behind a blanket permission.
What to watch next is how Apple translates the announcement into concrete API changes and UI prompts, and whether developers will adopt the scoped alternatives already offered. Industry observers will also be looking for any ripple effects on third‑party AI tools for macOS, as well as potential regulatory scrutiny of permission models that intersect with emerging generative‑AI capabilities.
