What is FileVault and how does it work?
FileVault is a built-in encryption feature in macOS that protects the data on your startup disk by encrypting it. This means that even if someone gains access to your Mac or startup disk, they won’t be able to read or access the data without the correct password or recovery key. FileVault works by encrypting the data on your startup disk, making it unreadable to unauthorized users.
When you enable FileVault, macOS creates a secure environment for your data by encrypting the startup disk. This ensures that even if your Mac is stolen or someone tries to access your data without permission, they won’t be able to read or access the files. FileVault uses XTS-AES-128 encryption with a 256-bit key, which is considered highly secure. This means that even the most advanced hackers would find it extremely difficult to break the encryption.
Does FileVault slow down my Mac’s performance?
