i bought leopard today because i finally wanted to upgrade from 10.4.11 to 10.5 and now im getting extremely frustrated. i put the disc in, it pops up i click the osX icon then it prompts me to click restart to start the setup process. i click it and then the computer restarts then loads up like normal and ntohing happens. all that pops up is a box that says "my name" computer and inside is my harddrive icon, network icon, and the disc icon. and nothing happens to upgrade, so before i sit on hold waiting to talk to someone at apple i figured id post it here. hopefully someone will have some insight.
