Encrypt a computer

When your security officer assigns you a Device Encryption policy, a dialog prompts you to enter your macOS password. After that, the encryption of your computer starts.

  1. Enter your macOS password.
  2. Click Enable or Enable and Restart.
    Macs using Apple File System (APFS) formatting do not require a restart, so only the Enable option is shown.
Disk encryption operates in the background, so you can continue with your work. For more information, see SafeGuard Native Device Encryption.

If turning on the encryption fails, contact your system administrator.
