# Apple adds stricter controls to macOS Full Disk Access

> Apple will require clearer user consent before AI apps can read all files, messages and browsing history on Macs.

Apple announced new limits on the macOS setting called Full Disk Access. The change is meant to stop AI assistants from getting unrestricted read‑write rights without a user’s clear approval. The company says the rule will apply only when a developer truly needs that level of access, and it will require an explicit user action.

## Why the change now?

The move follows a report that Meta’s Muse app claimed to see private messages on a Mac, a claim Meta disputes but which raised concerns. A Wired story also warned that a flaw in the ChatGPT Mac app could let attackers reach sensitive data. Apple says AI agents are becoming more capable, so the risk of hidden full‑disk permissions is growing.

## What will users see?

Developers will have to prompt users with a clear dialog before enabling Full Disk Access. The dialog will explain that the app could read files, mail, messages and browsing history. Until a user confirms, the app will not receive that permission.

## The facts

- Apple announced the new controls on 2026-10-02.
- Full Disk Access currently lets an app read files, mail, messages and browsing history.
- The change follows a TechCrunch report about Meta’s Muse app reading private messages.
- A Wired report cited a flaw in the ChatGPT Mac app that could expose data.
- Apple says future access will require “very explicit user action.”

## Why it matters

Mac users will now have to actively confirm before an AI assistant can scan their entire disk, reducing the chance of hidden data collection. This gives clearer visibility into what personal files an app can see, helping people protect their privacy. It remains unknown how quickly developers will adopt the new prompts or whether existing apps will lose functionality.
