Theres a good chance you may run into some problems, unless Apple includes device drivers for there whole product line on every cd. If that is the case it will run no prob, if not then your iBook's graphics, sound, fan control and 1000 other things wont work. I guess it cant hurt try... Ignore everything I just said if the cd that comes with your mac is the same exact one that comes in the box at the store, which I just realized to make life easy it most likely is....
