Information About Software and Mac OS X
For information about the compatibility of software applications with Mac OS X, or to read
more about Mac OS X, check the Apple website: guide.apple.com/macosx/.
Using Classic in Mac OS X
In addition to using Mac OS X applications, you can continue to use most Mac OS 9
applications in the Classic environment. When you start up Classic, Mac OS 9 software works
in Mac OS X just as it did in Mac OS 9, but doesn’t benefit from some Mac OS X features,
such as the look of the new interface. Simply open a Mac OS 9 application or a document
that requires Mac OS 9. If Classic isn’t running, it starts up.
Once you start the Classic environment, it continues to run in the background, even if no
Mac OS 9 applications are open. When Classic is running, Mac OS 9 applications and
documents open faster. You can set up your computer to start Classic automatically when you
log in to Mac OS X. Choose Apple (K) > System Preferences, click Classic, and select “Start
Classic when you log in.”
To quit the Classic environment, click Stop in the Classic pane of System Preferences.
Important
Your computer starts up only in Mac OS X. Mac OS 9 is not available as a startup
disk and previous versions of Mac OS 9 should not be installed on this computer.
