How to Switch Users in Mac OS Tiger

Click on the Apple icon in the Finder bar.
Scroll down to the 'Log Out' menu option. Notice it will also display the name of the user who is currently logged into Mac OS Tiger.
Wait for the user to completely log out. Once he has, the Mac OS Tiger welcome screen and login box will appear.
Switch users by entering your username and password into the login window and pressing the Return key. If the window appears to shake after trying to switch users, then you have entered an incorrect password and must reenter it.
Check the box that asks if you'd like to enable fast user switching.
Press the red jewel to close the Accounts registry and begin fast user switching.
