![]() However, it does contain a link to a separate internal document that cautions against tearing of this membrane, as that would require “a top case replacement”. The United States version of the Service Provider guide doesn’t refer to this padding membrane. Repair documentation and service videos will be available when keycap parts begin shipping.” This flexible enclosure is quite obviously an ingress-proofing measure to cover up the mechanism from the daily onslaught of microscopic dust. ![]() The procedure for the space bar replacement has also changed from the previous model. The 2018 MacBook Pro features a thin rubberized layer under its keycaps, covering the second-generation butterfly mechanism. “The keyboard has a membrane under the keycaps to prevent debris from entering the butterfly mechanism. The Service Readiness Guide for MacBook Pro that has been distributed to Apple Authorized Service Providers find such mentions. The main function of the membrane is to “prevent debris from entering the butterfly mechanism”. Website MacRumors fortunately managed to dig out an internal document where the Cupertino based giant has confirmed that the third-generation keyboard in 2018 MacBook Pro models are fitted with a membrane. An Apple patent claimed similar mechanisms for keyboard protection. Your keys don't spring back like mechanical switches do, and that has a noticeable effect on your typing. The company discovered a thin silicone membrane covers the problematic butterfly mechanism under the keyboard providing protection against dust and dirt. Membrane keyboardslike the Apple Magic Keyboardjust don't have the same kind of audible click and feedback of a mechanical keyboard. This was first discovered by a private company iFixit. The keyboard has a membrane underneath that provides cushion like support. So, you may not feel the difference, but there is definitely something extra in these upgraded versions. The older versions also had quiet keyboards and these ones are bit quieter. The remarkable change that has been brought is the new quiet keyboard. Hopefully the company extends that solution to future MacBooks as well-and eventually acknowledges why it exists in the first place.Apple has recently ameliorated the current line up of MacBook Pro by including 13 inch and 15 inch models. Regardless of how Apple frames its new keyboard, it clearly helps keep dust out and solves a vexing problem. But any more thorough solution would likely have required a total redesign of the keyboard, and of the MacBook Pro generally, rather than strategic tweaks. Pouring sand over the keyboard-don’t do that at home-caused a few keys to seize up right away in iFixit’s tests. We used to break those a lot, even being careful,” says Suovanen. Just going off of feel, I would guess that they changed the dimensions very slightly, and/or maybe the composition of the material they’re using for the clips. “The measurements are very, very slightly different. But iFixit found it could get them on and off on the new MacBook Pro without a hitch. Failing that, an entirely new unit might be needed, since removing individual keycaps risked damaging the underlying mechanism. Previous-generation keyboards were difficult if not impossible to repair Suovanen says Apple’s strategy was to hold the laptop at a 45 degree angle and hit it with compressed air. “I definitely think it’s going to reduce their headaches going forward, and certainly consumer headaches.”Īpple also appears to have done itself a favor in terms of repairability. “It’s not 100 percent effective at keeping debris out, but it’s pretty good,” says Suovanen. Specifically, a thin layer of silicone now sits above the keyboard’s butterfly mechanism-a protective layer that, yes, might make typing a little quieter, but definitely keeps more particles out. While Apple has offered to fix any affected keyboards for free for the next several years, the new MacBook Pro appears to be its first attempt at a design-based fix. While Apple has previously downplayed the extent of the problem, it’s pervasive enough to have inspired three class action lawsuits, and prompted a rare acknowledgement from Cupertino last month that something is amiss. ![]() Debris gets under the keyboard and has no way to get out again, resulting in unresponsive keys. Id rather use something that covers the whole area as the paper from factory. Better the imprint of the cloth - which can be wiped clean - than imprint from the keys that could possibly damage the coating. But a detailed teardown completed by repair site iFixit Thursday shows a much more likely catalyst: keeping out dust and other particles, so that the keyboard won’t break.Īpple’s previous keyboard design (found on MacBooks dating back to 2015 and MacBook Pros from 2016 until this most recent version) has been prone to key failure. The cloth at least protects the screen regardless of the imprint. It also introduced a new keyboard design, purportedly to make things quieter. When Apple introduced its new MacBook Pro last week, it didn’t just infuse it with faster processor and more RAM.
