Can anyone help me out with resetting my macbook pro to factory status? I will be selling it. So, it needs to be as completely new as when I first powered it up. With the new user account prompting & all that. Now, I have read up on my own and I know the part about pressing command-R during startup to load Lion Recovery. Also, erasing and reformatting the Macintosh HD using disk utility. What I do not get is the part about installing Mountain Lion through an internet connection. To do this, one has to sign in with an Apple id and a password. I have these. But I did not get Mountain Lion from the app store. I bought it a few days ago with everything preinstalled. My concern is to delete all personal data and my user account. If I sign in with my details to install the OS, wouldn't the laptop be already customized? Can someone please help me out on this? Appreciate it.
