Apple tightens macOS Full Disk Access as AI agents raise the stakes

Apple is tightening macOS Full Disk Access because AI agents make the permission far riskier. The company announced the move on 2 October, TechCrunch reported. Apple said new controls will demand “very explicit user action” before an app gets this level of access.

The setting lets an app read files, mail, messages and browsing history. Slashdot noted that it was originally designed for backup tools. Today, a growing list of apps asks for it.

Why Full Disk Access worries Apple

Apple’s statement was blunt. “Some developers are using Full Disk Access in ways that could put users at risk,” it said, adding that this can expose everything on a system without users’ full understanding. It also warned that risks “will grow substantially” as AI agents become more capable and autonomous.

The timing is notable. TechCrunch said the announcement followed reports that Meta’s Muse AI agent accessed a journalist’s private messages. Slashdot reported that Meta disputed that claim. TechCrunch also pointed to a flaw in ChatGPT’s Mac app that could have exposed sensitive data.

Apple’s message to developers was direct. They must ensure users genuinely wish to grant an app this extraordinary level of access. Users must understand the privacy implications too. TechCrunch said Apple did not specify a macOS version for the change.

The logic is easy to follow. A chatbot only sees what you type into it. An agent acts on your computer. It can open folders, read documents and send messages. If it holds full disk access, a single mistake or a single hijacked prompt can reach everything.

This is a trade-off, not a clean win. Users want agents that do real work. Real work needs access. Apple’s answer is friction: make people pause and choose. Developers will argue that extra prompts spoil the experience. Security researchers will reply that a pause is cheap compared with a leak.

Regulators are watching AI agents too. Our report on the FTC probe into OpenAI, Anthropic and METR shows the pressure building. Platform rules may move faster than law.

For now, check which apps hold Full Disk Access on your Mac. Remove any you do not need.
