What to Remove before selling Macbook? My macbook (feb 2008 white) sold on ebay, but I haven't shipped it yet.  I'm concerned about my privacy.  I can't wipe the hd clean because I sold the computer with valuable software on it.  What files should I remove so that the person who receives the computer can't log into my accounts?  And what other things should I do to ensure my privacy is safe?
The simple solution

Create a new admin account, then use it to delete your personal account(s).

When you delete a user, you have the option of performing a "secure erase" on their home directory:



Assuming you haven't stored any personal files outside of your home directory, this will do the trick.



The paranoid solution

If you want to be really thorough, the only way to ensure that none of your personal data remains is to securely wipe the drive. You can do this from Disk Utility by clicking "Security Options" on the "Erase" tab:



After that, reinstall your applications. None of your personal data will remain.
