Power off your computer, and then turn it on, holding command and R until you hear the start chime or see the apple logo. (This boots you into Recovery Mode). Then select disk utility, and there will be a menu on the left-hand side with a bunch of drives. Choose the one named, "Macintosh HD", and click erase. Then make sure Mac OS Extended (Journaled) is selected for format, and make sure the name is Macintosh HD (you can name it whatever you want, but Macintosh HD is what the factory names it). Then click erase in the bottom right. Afterwards, select erase free space from the same menu and choose how securely you want to erase it. Finally, exit disk utility, and select install OSX, and you will have a factory-reset Apple Computer. Note: if you are not on Mountain Lion or above, you will need the install disk to reinstall the Operating System.
