What is the password on my new Mac?

The operating system on every Mac since 2000 has been UNIX with a very Mac-like appearance. It requires users to log into the computer with an account, which has a user name and password. When we prepare a new computer, we NEVER put a password on the main account. You are welcome to add a password yourself, but we never ever do that. When you install software, or updates, the computer will ask for your password.... but you do not have one. Simply click on the 'Next' or 'Go' or 'Continue' button without typing a password. It will carry on and do what you want.
