About Mac OS X
Start up using Mac OS X and explore its advanced technologies, such as the elegant new user interface, incredible graphics capabilities, and added system stability and performance. Mac OS X manages your computer processes so you can concentrate on what you want to do. You don’t need to worry about restarting your computer if something goes wrong with one software application. Mac OS X shuts down just that application so you can keep working without interruption. The Mac OS X virtual memory manager allots the amount of memory your software applications need to run efficiently. When you’re ready to learn more about Mac OS X, read Welcome to Mac OS X.

You can set your computer to start up Classic automatically when you log in to Mac OS X. Choose System Preferences from the Apple (K) menu, click Classic, and select “Start up Classic on login to this computer.”
To quit the Classic environment, click Stop in the Classic pane of System Preferences. You can save any unsaved changes to your Classic documents and quit Classic.
Important Do not remove the Mac OS 9 operating system from your computer. For Classic to work, Mac OS 9 must be installed.
