Hi guys, If I try to install Mac OS X on my macbook it the installation says: "Mac OS X can not be installed on this computer" I have the original disk for this macbook. Before someone hit a command in the terminal like: sudo chmod /0700 or something to fix something which in the end did not work. After this I: -Formatted the disk several times. Also overwriting everything with zeros and overwriting 7 times, which I actually skipped after 5 times - Erased the parameter RAM holding Command, Option (Alt), P and R while starting up. I would be grateful for any hint how I can install. Thank you!
