We received a donated ibook which appears operational. Before we can pass this on to a student, I need to remove all information, etc that refers to the former owner and reinstall software. I saw references to Tiger, Panther, etc. How do I know what is on or would be accepted by the iBook we want to renovate? Is there a "best" source for the software? I need to ascertain whether such a purchase is worth while and have no idea of the cost involved. thanks for any help available. I do know the laptop has 1.5G Ram and if I remember correctly, was an 10.2 version OS
