Q: reset macbook pro to default settings

How do I reset my new 13" MacBook Pro Retina - 8 GB - 2.9 GHz - 512 GB storage?  I want to return it and want to reset it myself before I return.  I deleted my security settings (login and password) and now can't login.  Thanks.

MacBook Pro with Retina display, OS X Yosemite (10.10.5)

    What to do before selling or giving away your Mac - Apple Support


    Install or Reinstall OS X from Scratch

     

    Be sure you have backed up your files because the following procedure will remove everything from the hard drive.

     

    Boot to the Recovery HD:

     

    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears.

     

    Erase the hard drive:

     

      1. Select Disk Utility from the main menu and click on the Continue button.

     

      2. After DU loads select your startup volume (usually Macintosh HD) from the

          left side list. Click on the Erase tab in the DU main window.

     

      3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on

          the Security button and set the Zero Data option to one-pass. Click on

          the Erase button and wait until the process has completed.

     

      4. Quit DU and return to the main menu.

     

    Reinstall OS X: Select Reinstall OS X and click on the Install button.

     

    Note: You will need an active Internet connection. I suggest using Ethernet if possible

               because it is three times faster than wireless.

     

    This should install the version of OS X that you had installed.
