FileVault is a built-in disk encryption program available on Apple devices, such as Mac computers and MacBook laptops. It plays a crucial role in protecting sensitive data from unauthorized access. By encrypting the entire startup disk, FileVault ensures that even if someone gains physical access to your device, they won't be able to access your files without the encryption key.

FileVault is an essential feature for Apple users who want to safeguard their personal and business data. It provides an extra layer of security, especially in case of theft or loss of the device. The encryption process is seamless and transparent to the user, ensuring a smooth experience while keeping your data secure.

Examples:

1. Enabling FileVault:

   • Open "System Preferences" on your Mac.
   • Click on "Security & Privacy."
   • Go to the "FileVault" tab.
   • Click on the lock icon in the bottom left corner and enter your administrator password.
   • Click on "Turn On FileVault" and follow the instructions.

2. FileVault Recovery Key:

   • If you lose your recovery key, Apple cannot help you regain access to your encrypted data.
