I bought Tiger at bestbuy friday I knew leopard was coming out but my g4 wont support it. Im new to mac and I didn't know about programs like xpostfacto. So I have 30 days to return softwear and exchange it for the same softwear. So my question is that since they no longer sell tiger if I go in and exchange it will they give me leopard? Sorry if it doesn't make any since it is hard to explain.
