unlock a preference pane

To unlock a preference pane, click the lock at the bottom left, then do one of the following:

  • Enter an administrator name and password.

  • Place your finger lightly on Touch ID (if your Mac has Touch ID and it’s set up to unlock your Mac).

  • Double-click the side button on your Apple Watch (if your Mac supports unlocking your Mac with Apple Watch). See the Apple Support article Unlock your Mac with your Apple Watch.

Note: For some preferences, you must enter an administrator name and password—you can’t use Touch ID or Apple Watch.
