I am currently looking to sell my current 2007 MBP for the latest - I want to clear all my data securely so the guy I am giving it to will not be able to trace back any of my files. I know even if you simply reformat the OS and HDD you can still track back files (personal perhaps). How can I do a SECURE format on Mac OS X 10. Leopard? I want to have a safe feeling when giving it away. Thanks, and please help me response quick! I am exchanging it tomorrow! EARLY AM (EST). Thanks again! anyone?
