At very close inspection, the computer looks brand new.  Functionally, it is excellent (I immediately to Mac OS Ventura and configured it using Migration Assistant). It is important to note that this seller (6Ave) includes both the magic mouse and keyboard.  Moreover, I confirmed that the computer has a full one-year warranty from Apple; it can also be extended to a full three-year Applecare program. I will update my review if some issue comes up, but so far I am very happy to have decided  purchasing this particular unit.
