I got the Tiger SDK at WWDC and installed it that day on my PowerBook and have been using it ever since. For a variety of reasons I have decided I need to reinstall Panther to suit my needs though. So here is the problem: If I try to reinstall from the Panther CD it says "Cannot install OS X. A newer version is already installed" or something to that effect. Disk Utility doesnt seem to want to let me reformat the drive. How can I revert to Panther?
