Mac OS X 10.2: Some users cannot use Classic

When using the Classic environment to install software updates, installing Mac OS 9 system software updates or reinstalling Mac OS 9 may cause privilege changes to the Classic System Folder that prevent some users from using the Classic environment.

This document applies to Mac OS X 10.2 through 10.2.2.
This message may appear when trying to start Classic, "You do not have sufficient permissions to run Classic from the selected system folder."

To fix this, download and install Mac OS X 10.2.3 Update, or later.
