I have a power mac 5500/255 with a mac os 8.0 operating system on it. I recently got it as a gift for free by a person who desided to move over to a pc. Well, When i got it i was warned that the pc had password lock down on it due to the previouse owner. The computer never came with a OS install disk. So my question is how can i get past the passwords on this computer since i dont know them and the person that owned it before me doesent know. Any help at all would be wonderful becasue i want to be able to get passed all the clocks on it. I cant realy do much without the passwords. thanks!
