This issue has been discussed numerous times with no real solution: https://forums.macrumors.com/threads/something-rattles-inside-when-i-tilt-the-macbook.2052987/ So does your MacBook makes rattling/clicking noise (as if something is loose inside the screen) when you tilt it? Mine does that,I've taken it to Apple,at first they said it's normal and due to mechanism of Taptic trackpad, when I showed them other MacBooks that were not making this noise they agreed there is a problem and replaced the screen TWICE. they even replaced the whole LogicBoard with SSD attached,but the rattling is still there. So I want to find out how widespread this problem is? and why such an expensive and premium device should suffer from such primitive problems that no one can sort out?
