Starting Classic
When
Classic is started, it doesn’t actually boot Mac OS
9. Instead, it launches the Classic Startup process, found in
/System/Library/CoreServices. In turn, the
Classic Startup process looks for a Mac OS 9 system folder on the
system. If one is found, Classic will start; if not, you will receive
an error message, letting you know that Classic
can’t be started because there
isn’t a valid Mac OS 9 system folder on your
computer.
There are four ways to launch Classic:
- Launch a Classic application
When you launch any Classic application (one of the three application flavors the Finder recognizes; see Chapter 2), Mac OS X automatically starts Classic if it isn’t running already.
- The Classic preferences panel
Go to System Preferences→Classic→Stop/Start, and click on the Start button to launch Classic.
The table view under “Select a system folder for Classic:” lists every disk or partition on the filesystem that holds a Mac OS 9 System Folder. (If you’ve gone the usual route of installing Mac OS 9 and Mac OS X on the same disk or partition, then you’ll see just one choice here.)
- From the Classic menu
If you select the checkbox next to “Show Classic status in menu bar,” a Classic menu extra appears in the menu bar at the top of the screen as shown in Figure 3-1. From this menu, you can start, stop, and restart Classic; open the Classic preference panel; and gain access to Mac OS 9’s Apple menu.
