Not that I am expecting anyone to know, but....... Has anyone here been able to install OS 10.3 Panther on a "legacy" PowerMac using XPostFacto? My uncle purchased a copy of Panther (and opened it, thus making it non-returnable), and I have been struggling mightily trying to get it to install on his beige G3 PowerMac (300 MHz) with no success. And most frustratingly, the XPostFacto tech forum is down. I was able to install 9.2.2 on his computer without a problem, then installed XPostFacto, and when attempting to install Panther using it, it reports an error attempting to copy the extensions directory and then quits. If anyone has gotten Panther to install on one of those computers, I'd appreciate any tips you might have.
