Software Troubleshooting Tips and Tools Mac OS X only Starting with the PowerBook G4 (17-inch), the system will no longer boot into Mac OS 9. Mac OS 9 applications can still be used, but only in the Mac OS X classic mode. In locations such as the Startup Disk system preference pane, a Mac OS 9 folder will not show up as an option. Login window and account Mac OS X requires at least one user account to be established. This is the Administrator's account. By default, the Accounts system preference pane has the "Log in automatically [Admin's name]" check. This automatic login setting allows the system to boot into the Finder without having a log-in prompt. However, if this box is not checked, you will need a password to get to the Finder. In addition, you will need to create a user account after you re-install system software. Customer forgot password If the customer forgot the password for the computer: 1. Insert the Software Install and Restore DVD. 2. Restart the computer while holding down the C key on the keyboard. 3. When the installer appears, chose Reset Password from the Installer menu 4. Follow the on-screen instructions. Safe Mode The Mac OS X that shipped with the PowerBook G4 (15-inch FW800), has a new startup state called Safe Mode. Safe Mode is the state Mac OS X is in after a Safe Boot. A Safe Boot is a special way to start Mac OS X when troubleshooting. Starting up into Safe Mode does three things to simplify the startup and operation of your computer: 1. It forces a directory check of the startup (boot) volume. It is identical to using Disk Utility's Repair Disk or the fsck -fy terminal command. 2. It loads only required kernel extensions (some of the items in /System/Library/ Extensions). 3. It runs only Apple-installed startup items (some of the items in /Library/Startup Items and /System/Library/Startup items - and different than login items). Taken together, these changes can work around issues caused by software or directory damage on the startup volume. 8 - PowerBook G4 (15-inch FW800) Troubleshooting General Information

PowerBook G4 (15-inch FW800) Troubleshooting
General Information
Software Troubleshooting Tips and Tools
Mac OS X only
Starting with the PowerBook G4 (17-inch), the system will no longer boot into Mac OS 9.
Mac OS 9 applications can still be used, but only in the Mac OS X classic mode.
In locations such as the Startup Disk system preference pane, a Mac OS 9 folder will not
show up as an option.
Login window and account
Mac OS X requires at least one user account to be established. This is the Administrator’s
account. By default, the Accounts system preference pane has the “Log in automatically
[Admin’s name]” check. This automatic login setting allows the system to boot into the
Finder without having a log-in prompt.
However, if this box is not checked, you will need a password to get to the Finder. In
addition, you will need to create a user account after you re-install system software.
Customer forgot password
If the customer forgot the password for the computer:
1.
Insert the Software Install and Restore DVD.
2.
Restart the computer while holding down the C key on the keyboard.
3.
When the installer appears, chose Reset Password from the Installer menu
4.
Follow the on-screen instructions.
Safe Mode
The Mac OS X that shipped with the PowerBook G4 (15-inch FW800), has a new startup
state called Safe Mode.
Safe Mode is the state Mac OS X is in after a Safe Boot. A Safe Boot is a special way to
start Mac OS X when troubleshooting. Starting up into Safe Mode does three things to
simplify the startup and operation of your computer:
1.
It forces a directory check of the startup (boot) volume. It is identical to using Disk
Utility’s Repair Disk or the fsck –fy terminal command.
2.
It loads only required kernel extensions (some of the items in /System/Library/
Extensions).
3.
It runs only Apple-installed startup items (some of the items in /Library/Startup Items
and /System/Library/Startup items - and different than login items).
Taken together, these changes can work around issues caused by software or directory
damage on the startup volume.
