In Mac OS X 10.2 or later, the status of AppleTalk in Classic is always the same as the status of AppleTalk in Mac OS X. Use the Mac OS X Network preference pane to adjust AppleTalk status.
In contrast to prior versions of Mac OS X, you cannot use the AppleTalk control panel in the Classic Environment. Additionally, you cannot use the Chooser or AppleScript to change AppleTalk status.
Follow these steps:
1. Open System Preferences.
2. Choose Network from the View menu.
3. Click the AppleTalk tab.
4. Select or deselect the checkbox for Make AppleTalk Active, as desired.
5. Click Apply Now.
