Troubleshooting Information
Before or During Installation
Your computer doesn’t have a CD-ROM drive.
You can install the Mac OS using a CD-ROM drive attached to another Macintosh. Connect
both computers to a network, then use file sharing to access the CD from across the network.
See the onscreen Help for information about using file sharing with your computer.
To ensure a smooth installation, turn off any disk security or virus-protection software you
have installed. Then use the Extensions Manager control panel to turn off non-Apple
extensions and control panels. Make sure you have AppleShare extension 3.6.4 or later. (A copy
is available on the Mac OS CD; install it if necessary.) See the onscreen Help for information
about using the Extensions Manager control panel.
After you’ve turned off the extensions, restart your computer, then open the Installer and
install the Mac OS. Following this process will help ensure that incompatible extensions don’t
interfere with the installation process.
After the installation is finished, you can turn on your extensions and virus-protection
software. If you encounter problems after doing so, see “Resolving Software Conflicts” on
page 11.
You can’t start up the computer using the Mac OS CD.
With the CD inserted, open the Startup Disk control panel and click the CD icon in the Startup
Disk window. Then restart the computer and install the Mac OS. After installation, use the
Startup Disk control panel to reselect your hard disk, then restart your computer.
The Installer cannot repair your hard disk.
m
If you see a message that the disk can’t be fixed because a file is open, quit all programs. If
file sharing is on, turn it off. Then try installing again.
m
If you still get the message, use Disk First Aid, provided on the Mac OS CD, to see if it can
repair the disk.
m
If Disk First Aid is unable to repair the disk, try a third-party disk repair utility, if you have
one. Make sure you’re using the latest version of the utility.
m
If you don’t have a third-party utility, or if that utility can’t repair the disk either, you may
need to reinitialize the hard disk. First, back up your hard disk because reintializing erases
all the files on the disk. Then use the Drive Setup utility program, provided on the Mac OS
CD, to reinitialize the disk. For help with Drive Setup, open the program, then look in the
Help menu. After you’ve reinitialized the disk, use the Mac OS Installer to reinstall system
software, then reinstall your application programs and your documents from the backup
copies you made before you reinitialized the disk.
