Recently, Niels purchased a new MacBook Pro. A great computer, even if it’s a bit pricey. To compensate for this investment, he decided to sell his old MacBook Pro from 2013. The old MacBook was in a fairly good state and it had always worked reliably. A potential buyer however, rightly pointed out that the coating on the retina screen was damaged. As a result of which, the sale fell through. Such a bummer.
