This program installs Mac OS 8.6 on your computer in four easy steps. Follow the onscreen instructions. If you need help, click the Help button in each window. For more information and troubleshooting tips, see the installation manual.
System requirements
To install Mac OS 8.6, your computer must have a PowerPC microprocessor and at least 24 MB of RAM (32 MB recommended). If your computer has less than 32 MB of built-in RAM, you must use virtual memory. (Mac OS 8.6 automatically turns on virtual memory when you install it.)
You must also have at least 50 MB of space available on your hard disk. The Installer displays a message if you don’t have enough hard disk space.
Before you begin
• Turn off all security software, including At Ease.
• Start up your computer using the Mac OS 8.6 CD.
If you can't start up from the Mac OS 8.6 CD, also do the following:
• Turn off all non-Apple extensions and control panels.
• If you have a PowerBook, set it not to go to sleep.
• Restart your computer before opening the Installer.
If you're installing the software on a PowerBook, also do the following:
• Plug the PowerBook in so it's not using battery power and set it to not go to sleep.
• Turn off password protection in the Password Security control panel.
See the installation manual for more information about preparing your computer for installation.
