How to restore administration account on Imac

Imac_User1

I tried to make a new user and I needed up erasing the admin account somehow. So now I can't make any changes to my software nor can I delete apps. How can I fix this issue without having to bring it in to a tech.

There are several ways to do this. You can remove flag file for the setup process and it'll loop you back into the out of box setup process and let you create a new Administrator account. I would backup any data before attempting this. You're going to be required to access the recovery environment and accomplish via Terminal, or via Single User mode and Terminal. There will be additional steps if you have a new system with a T2 security chip. 

We do apologize for the delay in answering your post. If you want directions and to attempt we can certainly provide information for you. This is something I would recommend bringing in though.

I've got the very same issue on a mid year 2012 laptop MBP. I've tried the single user access and removal of the original setup file; but i think that mu unix knowledge din't find the requested file to be deleted.

Perhaps you can help/
