Hello everyone, I am selling my iMac and I recently re-installed OS X by holding down CMD + R, accessing the Disk Utility and erasing and reformatting Macintosh HD, and then re-installed OS X and left it at an "out of box" state. My only concern is that it asked me to authorize the installation of OS X before installing it by typing in my Apple ID username and password. If the new user were to finish installing and setting up the Mac, would anything of mine be accessible? I plan on de-authorizing the Mac as soon as it sells and such. Thank you!
