This simple back door hack for your Mac is exactly why FileVault should be enabled

“If you aren’t using FileVault on your Mac, it’s time to change that right now,” Jeff Gamet writes for The Mac Observer. “There’s a stunningly simple way to create a back door into your Mac using just the tools included with macOS, but all it takes to defeat the threat is FileVault.”

“FileVault is Apple’s full disk encryption feature that’s built into macOS. With it enabled, the entire contents of your SSD or hard drive is encrypted and accessible only when you log in to your user account.

    Guess it gets you clicks.

  3. Recently did a clean-install upgrade to High Sierra. FileVault and Time Machine did not play well so now FileVault is off. Maybe when I have a week to burn I’ll try again.

  4. I’ve been using File Vault with Time Machine as long as it’s been available with no issues. I recover stuff from Time Machine, too, so I know it’s working.
