I've had my topcase replaced and the problems just came back months later. Does anyone know if they have a solution to this problem or is their plan to just have me ship my machine to them every six months and avoid the class action?
(The 12-inch MacBook is different: some parts are attached to the bottom case, like, iirc, the motherboard.)
The solution is to use a keyboard cover. It also helps with noise as well.
Not an acceptable solution.
Dust and other small particles shouldn't defeat a laptop keyboard.
It is a solution though albeit I agree not a perfect one.
The problem has been acknowledged by Apple as being particles of dust, food behind the key mechanism. So the obvious solution is to cover the keys. I’ve had a cover for a while and now have had zero issues.
