New MacBook Pro teardown reveals protective membrane over problematic butterfly mechanism

New MacBook Pro teardown reveals protective membrane over problematic butterfly mechanism

That's because a tiny particle of dust can block keys, and fixing the problem can be quite a chore. Surprisingly, the third compatible monitor is Apple's own Thunderbolt Display, which has been discontinued for several years now.

Yesterday, Apple announced a minor refresh for its 13-inch and 15-inch MacBook Pro models, adding True Tone display technology, previously limited to iPhone X and iPad Pro. For the 15-inch MacBook Pro, single-core performance increased 12-15% and multi-core performance 39-46%.

As a long-time 2015 MacBook Pro user, I have been patiently waiting for a new MacBook Pro upgrade. The new MacBook Pros also have TrueTone displays and a new Apple T2 chip to handle payment security. But here's to hoping that the next generation of keyboards will completely fix the problem. It's clear that there is an audible difference between a 2018 MacBook Pro and an older model, although iFixit believes this is likely a byproduct of the addition of the aforementioned membrane rather than any specific work having been done to quieten keypresses.

A quiet keyboard is a neat perk, but if dust can still hinder regular operation, it's still a sucky keyboard. While a more reliable keyboard is undeniably a great selling point, it makes sense that Apple is not shouting about it at the moment.

According to iFixit, the new MacBook Pros come with a silicone cover over the butterfly switches that are supposed to stop dust from intervening with the key mechanism. And because the new notebooks are already available in stores, iFixit has already dismantled one. But they made no mention of a design change to the problematic butterfly mechanism used under the keys. Not-to our eyes-a silencing measure.
