For a while, I had only one user, say, User1, on my Mac's High Sierra. Then there arose a need to have some parental controls. To do that I created a new user, say, User2 and made it an admin while User1 was the controlled one.

At present, the need to control is no longer there and all of the information that I need to use is still under User1. My questions are the following.

  1. How can I add User1 to sudo'ers?

  2. Is there a way to get rid of User2 account and restore User1 to its original sole ownership?

  3. How can I make sure all of the deleted user's info and storage is scrapped and freed?

Any help or advice is appreciated.

  • Habe you tried to just undo what you did before: disable parental control on u1, set u1 to admin, relogin as u1, delete u2?

  • to clarify, You want to make the user 1 the admin, and delete user 2, knowing you will loose all data with user 2.

  • @nohillside I have not. I didn't know whether it was going to be as straightforward as that. Commented Nov 8, 2018 at 21:34
  • @Buscar웃 Correct. Nothing of value was acquired for User2. Commented Nov 8, 2018 at 21:34

1 Answer 1


As User 2

  • Open Users & Groups
  • Unlock it with Password
  • Disable (uncheck) parental controls for user 1
  • Enable User 1 as Admin

Log out from User 2, log in as User 1

  • Open Users & Groups
  • Delete user 2 (you will be offered to save or not the user data)
  • Are you sure a user can delete itself? And if this is possible, how should u1 get admin rights afterwards?
