Ok, my question is this. I have a 266mhz blueberry iMac that i want to install tiger on. It only has usb 1 (i know tiger isn't supported but i have xpostfato) anyway. How to I Install it? (i have a retail copy and the copy that came with my mac mini so i'm covered legally) I have a firewire/usb2 dvd burner and i can use filesharing. My Tiger is on a DVD. I don't want to send it in to get cd's i'd rather keep what i have. How do i do this? I was trying to use Pacifist but i'm not sure how to do this. I know i can't boot from the external dvd drive from the usb in the iMac because usb booting doesn't work. Any imput would be appreciated.
