Hello everyone I bought a used ibook g4... i recently bought mac os version 10.2.1 install cds and software cds because the person did not have the cds. I read the cd and it says i need to hold c when it boots to install, i do that but it does not work at all. Is there something I need to know? or did I buy the wrong one? my ibook has the tiger version and i have that disc. The reason why i want to reinstall is because I want to put everything back to factory settings and with my name instead of the person i bought it from. Is this possible or am i stuck with what i have right now? sorry for all the questions, this is my first apple... i worked on apple before but when it comes to installing i am ignorant. Thanks everyone in advanced who is willing to help me out.
