Chapter 1: Getting Your Mac Up and Running
If you enter the password incorrectly three times in a row, a password hint appears at the
bottom of the screen. Clicking the Forgot Password button also reveals the password hint.
(You enter password hints when creating a user account.)
New Feature
Clicking the ? icon button on the right side of the password field when logging in opens a pop-over that has an
option for resetting the password using your Apple ID, if you enabled that capability during installation (see
Appendix A). That pop-over also shows your password hint, should you want to see if before it’s automatically
displayed after three failed login attempts.

The login window’s icon buttons
In the login window, three icon buttons appear at the bottom of the window: Sleep, Restart,
and Shut Down. You can use these immediately, instead of having to log in to the Mac first.
They come in handy when you accidentally turn on the Mac and want to put it back to sleep
or shut it down.
You can configure Mac OS X so that the Sleep, Restart, and Shut Down buttons do not appear
in the login window. To do so, choose
➪ System Preferences and go to the Users & Groups
system preference, click the Login Options button, and then deselect the Show Sleep and Shut
Down Buttons option. By coupling this setting with the use of the Firmware Password utility
explained in Chapter 26, you can make it all but impossible for someone to circumvent the
requirement to log in.
Turning Off and Logging Out
When you’ve finished using your Mac, you have several options:
l
Put the Mac to sleep.
l
Leave the Mac on until the screen saver engages and then, later, the Energy Saver
system preference settings put the computer to sleep automatically. (See Chapter 28
for details about the Desktop & Screen Saver and Energy Saver system preferences.)
l
Log out of your account so people cannot access your Mac without first entering your
(or their) login password.
l
Shut down the Mac, which logs out of your account and closes the operating system,
before switching off the power. This option saves energy and provides greater safety
in case of power failure.
l
Restart the Mac. This isn’t really a way to finish working with your Mac; rather, it’s
an option typically used to complete the installation of certain system updates or to
change startup disks.
