"Why did my internal keyboard and mouse suddenly stopped working?"에 답변I have a 2015 Macbook Pro 13in and this has happened to me before. It happens all the time when I tilt the laptop when or holding it in at an angle. Sometimes it happens when I try to wake the computer from sleep. I then start button mashing and get some bluetooth interface box. Sometimes putting it back on the table and leveling it out helps. An occasional slap around the trackpad will fix it.
