This question already has an answer here:
I have two Mac Book Pro's laptop with me.
In one of the laptop, I am getting the following popup prompting when I try to change the login options.
It is prompting me like this:
In my another Mac Book Pro, it's simply showing the prompt like this. So I guess, it should show the same prompt message in first Mac Book Pro too.
How to get
administrator name to login into the first laptop? I tried with possible usernames & password (I have never changed my password) that I am aware of but they are not working.
How to find/get the administrator name back so that I can log in with my password.
