I am trying to restore my MacBook Pro to factory defaults. It is currently running 10.6.6 perfectly (when I startup normally, everything is fine) but the cds it came with, which I am trying to restore to, are 10.4.9. When I try to start up with the cds, it gives the following screen: The mouse is able to move around but the background is a jumbled desktop though it is interactive; when I move my mouse around and click, I can see in the white spaces changing to blue as though if I would be able to select and use the desktop if I know what the options were. I ran the hardware test (advanced - more than an hour) and nothing wrong was found. Is this a firmware issue or something I can fix by attempting to restore in a different way? Thanks in advance for the help!
