The new MAC OS 10.5 - Leopard system has been released for some time. Since the beta version, hackers have managed to solve the X86 installation issues for Leopard. Within just a few days of the official release (9a581), various patches and images of Leopard for X86 emerged like mushrooms after rain. With great curiosity about the Leopard system and admiration for Apple products, I made a series of attempts at installing Leopard, gaining some insights along the way. I'd like to share these experiences with my friends here.
