Apple to tighten macOS Full Disk Access controls, citing AI agent risks
In short
Apple said on October 2 that it will add further controls to macOS so that the “Full Disk Access” permission cannot be granted to an app without an explicit user action. The company said the growing capability and autonomy of AI agents increases the risk of allowing broad access to user data. Tech outlets reported that some developers have used the permission beyond its intended purpose, potentially exposing files, mail, messages and browsing history.
Why it matters
The change affects a permission that lets apps reach most data stored on a Mac, so it will shape how backup tools and other software work on the platform. Apple is framing it as a response to AI agents that can act on their own, a category of software that is expanding. Because the measure applies to macOS, users and developers outside Japan are equally affected, but the documents do not say when it takes effect.
Key facts
- Apple said on October 2 that it will introduce additional controls for the macOS “Full Disk Access” permission. [ 1 , 2 , 3 ]
- Under the change, the permission will be grantable only through a highly explicit user operation. [ 2 , 3 ]
- Apple cited the increased capability and autonomy of AI agents as the reason the risk has grown. [ 2 , 3 ]
- Full Disk Access is intended to let backup apps work properly by largely bypassing controls that protect personal data. [ 2 , 3 ]
- Apple said some developers used the permission in ways that could expose files, mail, messages and browsing history, and for communication apps could affect the privacy of the people a user talks to. [ 2 , 3 ]
- Apple said the aim is to let users make informed decisions about their data and privacy after clearly understanding the risk. [ 2 ]
Confirmed by several sources
Still unclear
- When the additional controls take effect and which macOS version will carry them. No document gives a rollout date or a version number; all three report only that the controls will be introduced.
- What the “highly explicit operation” required to grant Full Disk Access will consist of. PC Watch and Mynavi News describe it only in general terms, without steps or interface details.
- Which developers are said to have used Full Disk Access beyond its intended purpose. PC Watch and Mynavi News say “some developers” without naming any, and the claim is not attributed to a named Apple statement.
