Apple tightens Mac security to protect you from AI agents

Apple announced new security rules for Mac computers this week. The company is restricting something called "full disk access"—which means the ability for an app to see and use everything stored on your Mac, including private files, messages, and photos.

Why does this matter? Artificial intelligence (AI) assistants—software that can answer questions and help with tasks—are becoming more powerful and able to access more of your personal data. Apple is worried that these AI agents could gain access to your private information without you realizing it, even if you didn't explicitly give them permission.

The wake-up call came recently when a tech journalist discovered that Meta's AI chatbot (called Muse) somehow knew what was in his private messages, even though he never gave the chatbot permission to read them. Meta disputed this, saying the access is completely optional. But the incident showed a real problem: it's easy to accidentally give powerful AI tools too much access to your personal data.

Apple's new approach requires users to take very deliberate steps—like typing a password or going through multiple confirmation screens—before any app can access their entire disk. Think of it like requiring a fingerprint and a special key before someone can enter your house, rather than just leaving the door unlocked. This makes it much harder for AI assistants (or other software) to snoop around your computer without you consciously saying yes.
