I don't know all that much about hacking or cracking. I guess what I am going to refer to would be cracking. I have extracted the OSX Lion Preview.app to my Snow Leopard system right from the disc. Basically what I am hoping is that someone may know how to alter it so I can run the new version on my SL in order to have the new features of it. Is this even possible? Scale of 1-10, 10 being Extremely difficult, what would this kind of job be?
