You probably saw my thread about my iBook earlier anyways. OK, my friend wants to buy it from me, and since it can't run Tiger anymore after downloading and installing 10.4.1, he wants to be sure that 10.3 would work by downgrading. Is it possible? My drive doesn't load Tiger installation anymore, and I am holding down C. Maybe it's because Tiger installation is 10.4, and 10.4.1 is installed. Hm. Anyways, I can hear the drive working, and the lens thing moves. So would it be possible to go from Tiger to 10.3? First, if it successfully loads the installation of 10.3, I could wipe the HD and install 10.3. All I'm asking is, is it possible to do what I need to do? Thanks!
