No admin account on mac os
Suddenly I have no admin account on mac os.
All I did was to change the default account name from "user" to "myname"
When I try to make my standard account adminaccount I am prompted to enter admin username and password.
But what is the admin username and password now? I enter the old credentials but they dont work since I am not admin anymore.
MacBook Pro, macOS High Sierra (10.13.5)
