| Boot with the OS X install disk you intend to give with the sell. Before installing go to the installers menu item and find Disk Utility. In Disk Utility click the Erase tab then press the 'Security Options' and select a 35 pass. It will take a while (days) but it will wipe that drive REALLY well. : ) Then install a fresh copy of OS X. You good to go and you can sleep at night. Remember a fresh retail OS X does NOT included the iLife package!

| 1st reason - It's polite to sell a Mac with an operating system already installed!  (and not a blank hard drive...)If you are booted to the installer disk, and use that to wipe the hard drive, then it's a simple matter to just continue on with the install/restore. Do an Apple-Q when the install is complete and you see the first 'new user setup' screen. You can then shut down without running that setup, and the new owner has a brand-new fresh install of OS X (and none of YOUR stuff, eh?) 2nd reason (Aha! the real reason!) - you can't erase the volume that has your running operating system while you are booted to that system. You can do that while booted to a different disk, and the install/restore disk gives you the convenience of installing a fresh system (as noted above)

| Ok and what about the erasure of the free space? Isnt that enough? Heres what i would do, first i would delete the files i wouldn't want others to get their hands on using the "Secure empty trash" option, then id make an "erase free space" at the highest option, through disk utility. Do you recon even that wouldn't that be enough? |

| I gave you (in my first response) the absolute PARANOID guide to erasing the drive to DOD standards!
