I just recently bought an iMac and it came with the leapord installation discs and i tried putting leapord on my macbook but it says it cant be installed on that computer..Any ideas why....the only thing that i can think of why i can not install it on that computer is because the installion discs are for an iMac and not for a macbook and thats why it isnt working but im not sure......any ideas on why it is doing this???
