Locking and Unlocking Preference Settings

Some preference panes are locked for security reasons. If preference settings are all grayed out, the preference pane is locked to prevent non- administrators from making changes. Check the Lock icon at the bottom of System Preferences. If the Lock icon is locked, you need an administrator name and password to unlock it and make changes. If you log in as an administrator, the Lock icon is unlocked, unless you set a security option to have the preference panes stay locked. When you close the preference pane, it locks automatically.

Unlock a Preference Pane

Click the System Preferences icon in the Dock.

Click the preference pane icon (such as Security) that you want to lock settings.

Click the Lock icon.

To unlock, type an administrator name and password.

Click OK.

Click the Close button.
