I am looking for help and thank you for suggestion in advance.
Currently our Macs are build with a particular username and Password. Since on High Sierra we cannot delete the first created account how do i rename the account and change the Password to give the impression that first created account has been deleted and no longer exists.
You can hide an account by changing the User ID to a lower one than it is. The default is 501, if you take it down below 500 a bit it will become hidden. You can then also move its home from the /Users folder into the /private/var folder. Now you will have the appearance of no admin account, but it is there and you can log in with it.
