What You've Learned


In this lesson you learned the basic description of the various stages of the Mac OS X startup sequence. The following table lists these stages. For each stage, the table lists the corresponding visual and auditory cues. Once you have identified the stage where startup is failing, you can isolate the cause and fix it.

Startup Sequence Stage

Cue

Power On

Black screen

BootROM-POST

Flashing lights and LEDs, and activity sound as POST mounts all devices, including hard disks and removable media

One beep
No RAM installed

Two beeps
Incompatible RAM types

Three beeps
No good memory banks

Four beeps
No good boot images in BootROM

Five beeps

kernel

loginwindow

User Environment Setup

Desktop and Dock appear

In comparison to starting up, the process of logging out or shutting down is simpler. After a user chooses Log Out, Restart, or Shut Down from the Apple menu and confirms the action, loginwindow quits all of the user's applications, and if appropriate, resets hardware and restarts or shuts down the computer.
