How to enable the ROOT account on OS X

[DelJo63]

As delivered out-of-the-box, Mac OS X does not enable the ROOT account. Upon first BOOT, you create a user account & password and then set the Admin password. But that is not the same as becoming ROOT.

Sometimes, changing a config option or adding a control file needs to be able to "su root". First, activate ROOT by:

• Click the lock in the Directory Utility window.
  
• Enter an administrator account name and password, then click OK.
  
• Choose Enable Root User from the Edit menu.
  
• Enter the root password you wish to use in both the Password and Verify fields,
  
• then click OK.

Pick a good password as this account is well known and only your firewall & this password will protect the account.
