Apple announced on October 2, 2026, that it plans to introduce additional controls around Full Disk Access (FDA) in macOS, a permission that gives apps broad access to a Mac’s file system. According to Apple’s developer news post, FDA was originally created to let backup apps function properly, since it “largely sidesteps” the privacy controls Apple otherwise builds into its APIs for developers.
Apple said some developers have been using Full Disk Access in ways that put users at risk. Because the permission can expose “everything on their systems—including files, mail, messages, and even browsing history,” users may grant it without fully understanding what they are allowing, the company said. For communication apps specifically, Apple noted that this level of access can also compromise the privacy of the people a user is communicating with, not just the user themselves.
Apple framed the upcoming changes as a response to this gap between the scope of the permission and users’ awareness of what it grants. Going forward, the company said it will add controls intended to ensure that only users who “genuinely wish to grant an app this extraordinary level of access” can do so, and only through “very explicit user action.” Apple did not specify in the post exactly what form these new controls will take or when they will arrive in a macOS release.
Apple also tied the timing of this change to the growing capability of artificial intelligence agents. The company said that as AI agents become “increasingly capable and autonomous,” the risks tied to broad system access like Full Disk Access will grow substantially. Apple said addressing the issue is “critical” in light of this trend, suggesting that agents acting on a user’s behalf with FDA-level permissions could potentially access or act on sensitive data such as messages, files, and browsing history without a user’s full awareness.
Apple said its goal is to make sure users “clearly understand” the risks of granting Full Disk Access before they do so, so they can make informed decisions about their own data and privacy. The announcement did not include technical details, a rollout timeline, or specifics on how the new permission flow will differ from the current one, which typically involves a user manually enabling an app under Full Disk Access in System Settings.
