Ok, I got my hands on an old powermac G3 from a friend. It was previously running OS X Tiger. I decided to go ahead and reinstall Tiger from my CDs. After starting the Mac OS X installer, it would have me switch back and forth and back and forth from disc 2 and disc 3. Go figure. After doing this for a while it popped up a window that said 'Installer has quit unexpectedly.' So after trying again all afternoon, I install panther (10.3) and it works fine. I try to upgrade to os x tiger and it does the same thing. I just don't get it. I am very sure that my tiger discs work and in fact worked fine with another powermac g3 identical to this one. Any help would be appreciated. Thanks
