i have a restore image of 10.5 from a ppc ibook g4. the machine i want to restore it to has the same specs as the image. the only difference is my ibook g4 is running 10.4.11. im wondering if its ok to restore the 10.5 image over 10.4? i know ill loose everything thats not backed up elsewhere. i dont have any restore disk for my machine because it was bought second hand off ebay. please respond quickly.
