I have a problem with my MacBook Pro Mac OS X Lion 10.7.3 , I want to downgrade it to Mac OS X 10.6.1 . I have a installation disk but when my MacBook Pro start up with this disk it says "You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again." . I just follow it but it appears again. What should I do?


MacBook Pro, Mac OS X (10.7.3)
