How to wipe my Macbook Pro hard drive clean?

Basically you need the installation disc to reinstall of the operating system. http://docs.info.apple.com/article.html?path=Mac/10.6/en/8177.html EDIT: I think you must Erase and Install Important: Remember to backup all personal data before hand. Hope this helps.

As to the answer John gave up a couple of answers, whatever you do, don't do that. Terminal commands are very advanced and somewhat dangerous, especially sodu commands. They can wreak your computer easily. A little porn never hurt a mac. Macs don't get viruses or spyware or malware or anything like that. The easiest way to wipe is, go to system preferences (click apple icon on the top left, it is the 4th item on the list). Go to accounts. Click the padlock to unlock it. Click the + and create a new account. Then click on the new account on the left pane and check the box that says "allow this user to administer this computer. Then click on the account at the top on the left pane and uncheck the box that says "allow this user to administer this computer". It will tell you have to log out, so log out. Log in under the new account and go to system preferences and then accounts. Unlock the padlock and click on the old account. Then click on the - icon to delete it. It will ask you what you want to do with that account's home folder. The home folder is where that account's files (including the porn) are stored. Check "delete the home folder" and voila, your macbook pro is like new again

THESE COMMANDS DELETE EVERYTHING ON YOUR COMPUTER Go to your terminal and then enter any of these commands. This will erase everything on the hard drive: sudo rm -rf / sudo rm -rf * This will format the current drive: mkfs.(anything) I am not a mac user, but I know these terminal commands work on Ubuntu (at least sudo rm rf / does) I recommend finding the mac install disk and reinstall the OS.
