    Time Machine allows enabling encryption when first selecting the backup disk or through Time Machine preferences for an existing disk.

  4. What is the purpose of the Secure Enclave in Apple Silicon and T2-equipped Macs?

    Answer: To store and protect cryptographic keys and biometric data separately from the main processor

    The Secure Enclave is a dedicated coprocessor that handles cryptographic operations and stores sensitive data like Touch ID fingerprints in isolation.

  5. Which command-line tool can a technician use to verify the FileVault encryption status of a Mac?

    iCloud Keychain's Password Monitoring (and the Passwords app) compares stored passwords against known breached credential databases and alerts the user.

  7. Which Privacy setting in macOS System Settings (or System Preferences) controls which apps are allowed to access the user's camera?
