I'm selling my macbook in order to purchase a new one, how do I remove all my data so the laptop is back to the day I brought it?

Macbook, Mac OS X (10.4.11)

    Buy a USB external drive and "clone" your drive to it using SuperDuper. Then follow these instructions to erase and install a new system.

    EDIT: I thought it was a MacBook Air. Was in the wrong forum.

    Insert Install Disc 1 and boot the computer while holding down the C key. The OS X installer should load and you should choose the "Erase and Install" option.

    Assuming you still have the discs (OSX and Applications) that came with the machine, you can use them to restore the HDD to "out of the box" state.

    Before you do that, I'd recommend you download and run a utility called DBAN. This will completely wipe any trace of old data from the drive. Believe it or not, even if you format & restore the factory data to a drive, it is still possible to recover the old data from it (though not easy). DBAN overwrites every bit on the drive multiple times to completely scramble the data that existed on it. DBAN can be run from a USB flash drive or burned to a "live" CD (meaning the machine will boot from the CD instead of the HDD).

    When 'erase and install', select the 'security options' and use 'write data with zeros, 7-Pass or 35-Pass'. That will erase your private data if the new owner wants to 'check what was there before' he bought it.
