How do you add root account in mac os x?

Answer 1

The closest OS X has to a root account is the adminstration account. When you want to install or remove any program on the hard disk you will need that login and password. The person who set up the computer has that information. But you has to give it every time

If you have a username and password and want to set up a new account then you have to give the administrator passward and can do it. So you can have administrative privileges in one window, set up the other account, and when this is done, so is the privilege.

It is not enough to make a user with UID with value 1.

if you have administrative privileges you can start a "Root" terminal to run installation scripts. Otherwise, if you have the Administrator password, you can use the "sudo" command in front of the script (just as for Linux) and get the installation done.
