Hello all. Recently I got a hold on a iMac G3/400 indigo. I have gotten it to run 10.3 so far and I decided to update to 10.3.9 and the file that I got won't mount and it states "invalid checksum". Is any one having that issue as well? any suggestions on how to resolve it? On another note, maybe I should just forgo the update and go to 10.4 Tiger :-D I do have room and ram to do it.
