I just got this ibook today, and I was wanting to delete the previous owner but I cannot get the system pref app to work. It was not in the apps folder either. I reinstalled the combo 10.5.6 update and still nothing, all it does now is when I go to system pref from the apple icon it goes to the dash board, also the icon is not the gear box, it looks like a compass and pencil. This is my first mac, I just got it to play with, everything else works..and I have no restore disks..Any ideas??? Thanks in advance.
