Apple Tightens Mac Security After AI Reads Private Messages

Apple just announced it's tightening security on Macs because of growing risks from AI assistants. The problem centers on a setting called 'Full Disk Access,' which lets apps see everything on your computer—your messages, emails, browsing history, and files. This setting was originally meant for backup tools, but now AI apps are using it in ways that could expose your private data without you fully realizing it.

The change comes after a journalist reported that Meta's AI app, Muse, knew the content of his private messages even though he said he never gave it permission. Meta disputes this claim. Around the same time, a Wired report revealed a flaw in ChatGPT's Mac app that could have let hackers steal sensitive information. These incidents raised alarm bells about how much access desktop AI tools really have.

Going forward, Apple will require 'very explicit user action' before any app can get Full Disk Access. That means you'll have to clearly confirm you want to grant such broad permissions, rather than it happening quietly in the background. Apple says this is critical because as AI agents become more capable and independent, the risks of giving them wide access will only grow.

For you, this means more control over your privacy. You'll be asked directly before an app can see everything on your Mac, so you can make an informed choice. It's a reminder to check which apps have access to your personal data—and to think twice before granting sweeping permissions, even to helpful AI tools.
