When I try to install Tiger (currently running 10.3.9 on a 1.4Ghz Sawtooth Powermac), I get an error message. It tells me there's a problem with the install disc (I'm trying to do an archive and install). Just for comparison's sake, after a few failed attempts with my Tiger disc, I then tried with my neighbor's and got the same error message. Never had any problem installing versions 10.1 - 10.3. Anyone hear of this happening before? There are no problems with my computer that I've noticed, and my neighbor didn't have any trouble installing Tiger on his machine from his disc. I'm guessing there's something strange with my 10.3.9 that's preventing me from installing Tiger, but I have no idea what. Guess it's just desperately trying to cling onto life, before being replaced by the newer generation, huh?
