"Why did my internal keyboard and mouse suddenly stopped working?"에 답변I have the same issue my keyboard and trackpad totally disconnected on my 2015 MacBook Pro 13". It randomly started doing it I haven't dropped it or spilled water etc... I can get my keyboard and trackpad to work if I press down a few times on the laptop with both hands on either side of the trackpad (pretend you're giving it CPR lol), so my only guess is that a ribbon cable is loose somewhere. It's kind of irritating to do that every couple days because it keeps doing it, but at least I can use my keyboard.
