Hi there, a couple of easy questions I hope. What is the simplest was to increase the memory on a 10GB Imac G3. 9.7GB are used up and there isn't much I can delete to free up space. It is a friend's computer, she is not mac savvy. Also, I am considering rebooting the system as there is an account on there with a forgotten password and the original administrator password is long forgotten. What would be the best way to go about doing this? I have 10.4 os discs, with extra memory would this work ok? Thanks in advance.
