How to perform a Mac OS 9.2.2 clean installation using Mac OS X 10.2 or 10.3 Panther Software Restore CDs:

  1. For Mac OS X 10.3 or later, open Disk Utility, then, from the File menu, choose Fix OS 9 Permissions. For Mac OS X 10.2.8 or earlier, locate and change the permissions settings of the Mac OS 9 System Folder so that you own it.
  2. Open the Mac OS 9 System Folder, create a new empty folder, and drag the Finder into it.
  3. Rename the Mac OS 9 System Folder to something such as "Former Mac OS 9 System Folder". Tip: Do not use "Previous System Folder".
  4. Open Software Restore, and select to restore only Mac OS 9.
  5. Open Classic preferences and verify that System Folder (the one that was just installed) is selected for the Classic environment.


When you are finished moving any items from the "Old Mac OS 9 System Folder," (such as preference files for Classic applications, unless "Use preferences from home folder" is selected in the Classic preference pane) it can be deleted.
