I would like this question to be reopened.
Add details and clarify the problem being solved. This will help others answer the question. You can edit the question.
As per the close reason.
The reason why I ask this is because I am curious about how MacBooks work. I do not use a MacBook, but rather a Windows laptop. So please do not try to post "bug fix" answers thinking that I am having problems with my computer.
There's no actual problem to be solved
