FAQ

• What is FileVault disk encryption
  
  • FileVault is the macOS built-in disk encryption feature. It's designed to encrypt your Mac's hard drive and all of the files located on the drive. FileVault full-disk encryption (FileVault 2) uses XTS-AES-128 encryption with a 256-bit key to help prevent unauthorized access to the information on your startup disk. Once FileVault is enabled on your Mac, all existing data will be encrypted. From then on, any new and changed data will be automatically locked down and password protected on boot to prevent unauthorized access.
• How do I unlock a FileVault encrypted Mac?
  
  • Unlocking a FileVault encrypted MacBook is completed when you log in using your password. The drive will be unlocked after a system boot or reboot.
• What happens when I change my Mac password?
  
  • When you change your password, the FileVault password is synced at the time of change.
• What happens if you forget your password and can't unlock your Mac?
