Update : Apple replaced the screen again, they also replaced the whole logic board with 512GB SSD attached to it.
and they couldn't fix the problem.
the rattling is still there.
it is definitely from the screen, if you hold the screen with your fingers, it won't happen.so something is loose there.
I'm going to take it back one more time, if they couldn't fix it,as much as I love Mac OS,I will move back to Windows.there are some amazing Windows machines out there and none suffer from such primitive and un-acceptable flaws.
