New MacBook had user accounts already; I deleted admin and can’t get back in

administratordeleting

So when I get this new machine…there is already a user on it called "mac"…for my convenience they said. There is also another user already there named "admin"

well..i'm new to apple but when it's my pc, I am the admin. so i erased the "admin" they made (and for which they gave me no password for this account".

so i deleted it. now no one can log in, i can't use apple id, I've changed the passwords several time successfully only to attempt to make an edit or log in and get the message that an admin has to give his username and password….but i made myself the admin!!!!! why can't i log in with my username and the correct password i regenerated?

it's been hours of trying to make new admins, resetting passwords, everything… mount -uw, rv/ etc. it is totally messed up.

and this company did this account making for my benefit…? i can't get system assistant to do anything or even activate again. I've reinstalled OS 10.10…nothing. does anyone? know if i have to start at square one, reinstall yosemite or is there a way to fix this? much appreciated.

I would suggest you to reinstall OS X and doing it not on the top of the existing version. Start Mac in Recovery mode (hold Cmd-R keys pressed on boot). When in Recovery mode - select Disk Utility, format your disk, exit Disk Utility and select Install or reinstall OS X.

P.S. If you have your files stored in Mac - backup ones before formatting the disk.

Windows – Adding a MAC to a Windows Domain – well not quite

First off, Macs will happily bind to Active Directory domains - there's some variation between versions of AD and OS X, but if you're on AD 2008 or newer and OS X 10.8.3 or newer you won't have any problems. Use the Accounts preference pane, open Directory Utility for more control, or use dsconfigad from the Terminal. Once a Mac is bound, you will see it in your AD domain's Computers, just like anything else.

The UUIDs will be different, based on the order of account creation, but there is no functional difference between any two accounts that have been granted administrative rights. You can also specify AD groups when binding to grant admin rights (typically AD domain and enterprise admins).

Accessing the SMB share will be based upon that share's owner and permissions. If the user logs in to the Mac with his AD credentials, they should be able to easily connect to the share; with a small amount of effort you can easily add the share to auto-mount at login.

MacOS – How to create a script to create/modify local admin accounts

This is what I came up with:

It also uses http://magervalp.github.io/CreateUserPkg/

#!/bin/bash
# This script will first check existing accounts for presence of USERNAME or admin    or administrator
# If found, it will change the password to PASSWORD
# If none are found, it will run the package create_USERNAME-1.0.pkg which creates an account with Full Name = Administrator, Account Name
# (short name) USERNAME with the password.

function checkusername () {

local test1=$(dscl . -list /Users | grep -i USERNAME)
local test2=$(dscl . -list /Users | grep -i admin)
local test3=$(dscl . -list /Users | grep -i Administrator)

if [ "$test1" = “username” ]; then
  echo the username username already exists
  echo setting password
  dscl . passwd /Users/username PASSWORD
  exit 
else 
  echo
fi

if [ "$test1" = "Username" ]; then
  echo the username Username already exists
  echo setting password
  dscl . passwd /Users/Username PASSWORD
  exit 
else
  echo 
fi

if [ "$test1" = “UserName” ]; then
  echo the username UserName already exists
  echo setting password
  dscl . passwd /Users/UserName PASSWORD
  exit
else 
  echo
fi

if [ "$test2" = "admin" ]; then
  echo the username admin already exists
  echo setting password
  dscl . passwd /Users/admin PASSWORD
  exit 
else 
  echo
fi

if [ "$test2" = "Admin" ]; then
  echo the username Admin already exists
  echo setting password
  dscl . passwd /Users/Admin PASSWORD
  exit 
else 
  echo
fi

if [ "$test3" = "Administrator" ]; then
  echo the username Administrator already exists
  echo setting password
  dscl . passwd /Users/Administrator PASSWORD
  exit 
else 
  echo
fi

if [ "$test3" = "administrator" ]; then
  echo the username administrator already exists
  echo setting password
  dscl . passwd /Users/administrator PASSWORD
  exit 
else 
  echo
