Yes I know Im new to the mac but bare with me. I just aquired a ibook 800 G3. Im a former pc'r and have a few questions. I would like to install a clean install of OS X 10.2 and was wondering if i need a serial number for it. First I bought the computer with no software. Then I aquired OS X and all the ibook trimings second hand. They said it wasnt registered. ( I hope) I have no idea -- This is like learning spanish I just think english first then try to translate. any suggestions on where to begin?
