How do I restore my macbook pro to factory setting

Answer 1

Lion installs both itself and a Recovery HD. Booting the latter is how you reinstall Lion or fix things with Disk Utility. So, what you can do is this:
Install or Reinstall Lion from Scratch
If possible backup your files to an external drive or second internal 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. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
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.
Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Install button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.
Now, this will completely erase the volume in which Lion is currently installed. When you then reinstall Lion it will be like coming fresh from the factory ready for a new user. I hope this is a working solution for your problem. If it is not, then I would encourage you to create a new topic more relevant to your needs which will solicit others to offer help. That isn't going to happen in someone else's already old topic. Had I not forgotten to stop email notifications from this topic, then I never would have been aware or your post.
