I wanted to put parental controls on my computer before I learned that administrator users can't have parental controls (makes sense to me now). But somehow I still managed to enable parental controls for my administrator user, and it didn't give me any warning message.
I can tell that enabling parental controls really did work because some websites are blocked. This persists even after rebooting my Mac.
Now I want to turn off parental controls, but I can't do it. When I try to turn it off in System Preferences, I get this error message (video):
You cannot enable parental controls for an administrator account. Create a new user account, and then enable parental controls for the new account.
So how can I turn off parental control for the Admin user?
