FileVault

FileVault is like a big safe that keeps all your computer's important information locked up and safe from bad guys who try to steal it. It's like a secret code that only you and your super-smart computer know.

When you turn on FileVault, your computer will make a special password that only you know and keeps all of your important files like pictures, documents, and things like that inside that safe. This makes it very hard for anyone else to get to your information if they don't know the password.

So, if someone bad tries to steal your computer or get into it without permission, they won't be able to read or steal anything because your information will be hidden behind a strong password. It's like having your own superhero bodyguard keeping you and your stuff safe!
