Why is it exactly, that you cant install Mac OS X onto a computer with no loaded operating system. Meaning why cant I take a 2 year old computer(guess I better add that it was probaly meant for windows, its not a mac built comp.) that never had an OS installed on it, and install OS X? Im new to the whole mac thing, Ive used anything but windows, Im hoping to buy a Mac laptop sometime this summer. And if anyone can help, I know as of now you cant run OS X alongside windows XP, but what about virtually using emulators.?
