create multiple accounts, go to your system preferences, and select
accounts, click on the lock
on the bottom left and enter your password to make changes. Then click
the plus button. The first thing you need to decide is if the new user
should have administrative rights, meaning d o you want them to be allowed
to make changes to the system settings, or download updates or install
applications, unless you are concerned about the other user having these
kind of rights, it’s a good idea to change this to administrator.
Next decide on the user name, tab down and the short name will be automatically
entered for you. Now type in a password, and verify the password. If
you have trouble remembering your passwords then it’s a good idea
to enter a password hint. Now hit create account and that’s all
there is to it!
