Hi there I am thinking of buying a brand new and sealed MacBook Air 13" (2013) from someone, as I found it a lot cheaper. They have proven it's sealed by providing some photos of the box. They have also provided the serial, which states the following in the Apple Check Support Coverage website. Does this mean that they have never registered it? And when I boot up and register the Mac with my Apple ID, I will then get the standard 1 year warranty in my name?
