You see a message about updating the firmware.
Some computers require a firmware update before installing the Mac OS. Firmware is control
software that’s built into your computer. Follow the instructions for updating firmware in the
CD Extras folder on the Mac OS CD before proceeding with the installation.
The Installer cannot update the hard disk driver.
The Installer cannot update non-Apple hard disks. Use the disk utility recommended by the
manufacturer of your hard disk to update your drivers before installing the Mac OS. Make sure
to get a version of the utility that is compatible with the software you are installing. An old
utility will not be able to update your disk with the most current driver.
You see a message that there’s not enough memory to use the Installer.
Make sure you’ve started up your computer from the Mac OS CD. If you can’t start up from the
CD, quit all open applications and make sure you’ve followed the steps described in “You can’t
start up the computer using the Mac OS CD.” on page 9.
You see a message that there’s not enough disk space.
Make more space available on your hard disk by removing some files from the disk. Copy the
files you want to keep to another disk, then drag them to the Trash and choose Empty Trash
from the Special menu to delete the files. You don’t need to quit the Installer before you
remove files from the disk.
You see a message that the System file cannot be modified.
Make sure that you’ve started up your computer using the Mac OS CD. If you can’t start up
from the CD, make sure any security and virus-protection software is turned off. See page 9 for
other steps to follow when you can’t start up from the CD.
You see a message that an item cannot be replaced.
The Installer is attempting to replace a file, but there is a folder on the disk that has the same
name as the file being replaced. (Files cannot replace folders.) Find the folder on your disk and
rename it, then try the installation again.
You see a message that the installation was not successful.
Make sure that you’ve started up your computer using the Mac OS CD. If you can’t start up
from the CD, make sure any security and virus-protection software is turned off. See page 9 for
