How can I disable password for system preferences lock? How can I permanently unlock all system preferences?
Solution 1:
The settings stay unlocked, just do not click the "lock". This will keep the stuff unlocked until you want to lock it again.
Solution 2:
The inverse version of the answer on how to enable the lock:
Go to Security & Privacy, then Advanced.
uncheck the box for Require an administrator password to access system-wide preferences
That should ensure all the lockable prefs default to unlocked.
