Good luck getting OS X installed on a 6500. I've been trying for days. Now it's a last ditch effort of installing it on another Mac and moving the HD into the 6500/300...

That said, I've run 10.2.8 on a 9600/400 (604e 350 overclocked to 400 MHz). It runs fine, but it still seems slow compared to a G3.

Peace,

Drew
