I want to change the boot up screen. I hate the white screen with the boring flat grey apple. I want a black screen with silver apple icon. (Just like the iOS booting up screen). Where can I find the folder that contains the files such as the background color, apple logo, and clock wheel icon? I know it is possible. It was done using BootXChanger for Snow Leopard but it was really restricted and does not work on Mac OS X lion.
