I have a mid-2007 Macbook. I bought a copy of Mountain Lion and wanted to download it for use with another computer but the system will not let me. It says, "We could not complete your purchase. OS X Mountain Lion is not compatible with this computer." I want to use it with **ANOTHER** computer! Why did it let me pay them if I couldn't download it!? Obviously, I can't download it from the other computer or I would. Is there any way to bypass the check so I can download the installer? I know that it is incompatible with my Macbook and I have no intentions of trying to install it onto it. I paid for it, I should be able to download it from any computer I want, compatible or not! Please help, if you can. Can it be done, or should I be looking for other sources?
