Apple is changing one of the most powerful settings on the Mac. The company said it will tighten controls on Full Disk Access, which lets an app read almost every file on a computer, including email, messages and browser data, MacRumors and TechCrunch reported. Apple cited new risks from AI agents.

Today, users can grant Full Disk Access to apps such as backup tools, antivirus software and developer utilities. Once granted, the access is broad and lasting. Apple says AI agents, which can browse, click and run tasks on their own, raise the stakes. An agent with full access could be tricked by a malicious website or file into reading or sending private data.

Yahoo Tech called Apple's move the first operating-system-level change aimed directly at AI agent risks. Macworld and AppleInsider also reported the plans. Apple has not given a firm date for the changes or full details of how apps will need to ask for access.

For most people, the change should mean more prompts and clearer choices. Developers of backup and security tools may need to update their apps so they keep working.

Some background: Apple added Full Disk Access as part of its privacy controls in macOS Mojave in 2018. Over time, it has added more permission prompts for the camera, microphone, screen recording and files. Critics sometimes call the prompts annoying, but Apple argues they protect users.

The timing matters. AI agents from OpenAI, Anthropic, Google and others are spreading quickly, and many run directly on personal computers. California has just subpoenaed OpenAI over security incidents involving its agents.

Mac users can check which apps have Full Disk Access now by opening System Settings, then Privacy & Security, then Full Disk Access.

What we know: Apple will tighten Full Disk Access controls because of AI agent risks.
What we don't: When the changes ship and how they will work in detail.
