I bought my powerbook on eBay. It was sold with a clean installation of leopard. The seller purchased a family pack for his family's use and installed it on this one before he sold it. So obviously, he shipped it without the restore discs. Under the user agreement, is it wrong for me to use this version of leopard? I am not sure - he bought it and installed it on a computer which he owned and then sold the computer. I think this seems more 'wrong' because of how new leopard is--if he was shipping it with a copy of tiger (now outdated, but for the sake of this assume tiger also being purchased in a family pack) it would seem more acceptable. So do I need to buy the leopard disc just for the sake of being in the clear? Otherwise stated, if a computer bought with Panther included is upgraded to tiger or leopard via family pack, does it have to be downgraded to be sold? Even if the answer is no, I realize that I ought to buy a copy anyways for its purpose. But if the answer is no and there is a way of creating a restore disc from my computer I could consider that (but I don't know if it is possible). That said, I am really asking if this is morally correct, not physically able. I would like to keep my conscience clean. EDIT: I have seen the sticky on this topic before posting, although this particular circumstance was not discussed.
