MacBook Air, 10.13.6 High Sierra.
I tried changing the name of the user on my macbook and accidentally deleted the administrator account. The current user is my user but it says standard under it, there is no admin account on the computer.
I searched on google and I found a solution. Now, when I shutdown and press Command+S a wall of text appears. This text is scrolling so quickly that I can't enter any other command.
Here are the commands I found:
mount -uw /
I also found a solution on this site however, I get the same result with the text moving quickly.
Also, I think I need to mention that my Mac has a problem with wi fi and won't connect when it is not logged in.
What can I do to fix this problem?
