Problem: Unable to Repair Disk Permissions?
In most cases, this is caused by the absence of certain package files in the /Library/Receipts folder. These files contain the information needed by Disk Utility and OnyX to repair disk permissions. Fortunately, the solution is simple. Insert the Panther (OS X 10.3) Install Disc 1 and double-click on the CD icon to open its root directory. Open the /System/Installation/Packages folder and copy the BaseSystem.pkg, AdditionalApplications.pkg, AdditionalFonts.pkg (if installed), any applicable packages which end in 'PrinterDrivers.pkg' and any applicable language packages to your /Library/Receipts folder.
This will allow Disk Utility's 'Repair Disk Permissions' to function again. Alternatively, you may be able to copy these files from another computer running Mac OS X 10.3.x.
