Classic (System Preferences)

The Classic panel of System Preferences was around with Mac OS X since the very beginning, even in the Public Beta. It manages all options related to the Classic environment.

As of Mac OS X 10.4, this pane is no longer present in new computers unless Classic is installed from a CD. With the Intel-based Macintosh computers of January 2006, this pane was history -- no Intel-based Mac is capable of supporting Classic.

Mac OS X Public Beta
Nothing more than a clickable list, where the user could select a volume with Mac OS 9 installed, and a checkbox which enabled Classic to start automatically upon login (Start up Classic on login to this computer), were present in the version that accompanied Mac OS X Public Beta.
