iFixit reports that the third-generation spacebar separates easily - without permanent damage. On the second-generation butterfly keyboard, it was nearly impossible to remove the spacebar keycap without breaking it. One other change with this new keyboard is a redesigned spacebar. In an internal documentation, it is more open about the keyboard being more reliable. It’s just the chances of dust getting in are greatly reduced with the 2018 models.Īpple is telling customers that the new keyboard is merely designed to be quieter. Over time, you only need a couple specks of dust to get in the keycaps and the keys will get stuck. Clearly, the 2018 model is greatly improved in regard to reliability, but it remains to be seen just how much better it is in real-world use. The non-cocooned 2017 keyboard was “almost immediately flooded” in the particles, unsurprisingly. iFixit placed some sand particles into the ‘danger zones’ of the keycaps, and confirmed the keys will break/become-unreliable when that happens, just like the second-generation butterfly keys. Naturally, dust can and will get through these holes over time.

However, the silicone covers have to have holes in them to allow the keycap clips to attach. iFixit showered a 20 MacBook Pro in dust particles and then compared the result.Īs shown in the photo, the blue paint particles coat the outside of the keycaps and the edges of the membrane, but the silicone covers stop most of the particles from getting into the key mechanism - which is what causes the sticky key issues on the previous models. How well does the silicone membrane protect the butterfly mechanism? Pretty well. IFixit has followed up on its initial teardown with some focused testing on a the new third-generation keyboard present in the 2018 MacBook Pro.
