Quick Answer
- On October 2, 2026, Apple said it will add extra controls to macOS Full Disk Access, which gives an app access to almost everything on your Mac.
- Users will need to take “very explicit user action” before granting it.
- Apple named always-on AI agents as part of the concern. Meta’s Muse and OpenAI’s Dots were named in reports.
- Apple has not said when this starts or which macOS version gets it.
Full Disk Access is the strongest permission an app can ask for on a Mac. Apple now says some developers are using it in ways that could put people at risk, and AI agents are a big reason it is stepping in.
What is Full Disk Access on Mac?
It is a privacy permission that lets an app read protected areas of your Mac, such as files, mail, messages and browsing history. Apple’s statement says apps with this access can expose everything on a system, often without the user fully understanding that.
A normal app rarely needs it. Backup tools, disk utilities and some security apps are common reasons to grant it.
What did Apple announce?
According to MacRumors, Apple said it will introduce additional controls around Full Disk Access so users must make a very explicit choice before an app gets it. Apple also warned that as AI agents become more capable and autonomous, the risks of this level of access will grow substantially.
Why are AI agents the trigger?
An always-on agent works best when it can see your files, mail and messages, so it often asks for broad access. Reports named two examples:
- Meta Muse: Aiweekly’s coverage says users reported it reached private messages without clear consent. You can read how we covered the Mac app in our Meta Muse for Mac article.
- OpenAI Dots: an always-on agent launched at DevDay. Our OpenAI DevDay 2026 guide explains what it can do.
Aiweekly also points to a documented flaw in the ChatGPT Mac app that could have exposed sensitive data. We have not confirmed those details independently, so treat them as reports.
What is NOT known yet
Apple did not say:
- Which macOS version will include the change. MacRumors mentions macOS 27 in its report, but Apple did not confirm the timing.
- When the new controls will start.
- What exact steps you will have to take.
- What developers must do to comply.
Until Apple publishes more, anything beyond the points above is a guess.
How to check which apps have Full Disk Access on your Mac
This is the standard macOS path and works today:
- Open System Settings.
- Go to Privacy & Security.
- Click Full Disk Access.
- Review the list. Turn off any app you do not recognize or no longer use.
If an AI agent asks for this permission, ask yourself whether it really needs it. Many tasks can be done with access to only a single folder. For background, our explainer on what AI agents are covers why they ask for so much.
Is Amazon also pushing back?
Yes, from another angle. Amazon blocked the Meta Muse agent from its shopping pages. Read the details in our report on Amazon blocking Meta Muse.
