When selling a computer you should always make sure you clear out any and all data you've put on the computer. The best way to make sure of that is to do a factory restore. While you think backing up and deleting is enough it's always best to do a full reset to clear any and everything.
This tutorial will show you how to factory reset your OS X computer from the built-in recovery.
Back up any important data you need before you being the restore.
If you are restoring on a MacBook KEEP IT PLUGED IN TO POWER UNTIL THE RESTORE IS COMPLETE! If the computer powers off in the middle of a factory restore it can cause severe damage to the system and this will greatly hurt the selling value of your computer.
When reinstalling OS X an internet connection is required.
