Apple Tightens macOS Full Disk Access Controls Over AI Agent Risks

My take: Apple announced it's tightening macOS "Full Disk Access" controls, the permission that lets an app see everything on your computer: files, mail, messages and even browsing history. The reason it gave was direct: as AI agents become more capable and autonomous, that level of access grows increasingly risky. The announcement follows reports that Meta's Muse agent accessed a user's private messages without clear permission, plus a reported flaw in the ChatGPT Mac app that could expose sensitive data.

This feels like a useful signal of where the market is heading: Apple, which doesn't build these agents, is the one forced to put up guardrails because the companies that do build them don't always put user permission first. For anyone running AI agents on their computer to automate work tasks, email or files, this is a good moment to check what full access permissions you've handed each tool, instead of just trusting it "works fine" because it's convenient.

If you run a business or handle sensitive client information, it's worth being even more careful: give each AI agent only the access it actually needs for the task you asked it to do, not full access to your system just because it's faster to set up.

Have you already checked which AI apps have full access to your computer, and whether they genuinely need it?
