If you own a MacBook or MacBook Pro with a butterfly keyboard, the chances are good that you may have experienced an annoying keyboard issue where some keys become unresponsive. The new MacBook Pros also have TrueTone displays and a new Apple T2 chip to handle payment security. But this is Apple we're talking about, so you shouldn't be surprised.
As per the patent application, the gasket would comprise of a layer that would act as a membrane to block dust particles. iFixit now says that's what the new MacBook Pro keyboard contains, and that the sound of the keyboard is quieter as a side effect of the silicone membrane.
As a long-time 2015 MacBook Pro user, I have been patiently waiting for a new MacBook Pro upgrade. But here's to hoping that the next generation of keyboards will completely fix the problem. The company updated the MacBook Pro with new True Tone displays, updated processors, more RAM on the higher-end variants, and third-generation butterfly keyboards. We suspected at the time that Apple fixed the major keyboard issue that's been affecting all MacBook Pros since the 2016 redesign, but Apple would not confirm it officially. Except the patent mentioned, the design was to help "prevent and/or alleviate contaminant ingress" and not to make typing quieter. Although this is just an opinion, iFixit has backed up its claim with an Apple patent, that shows the exact same design, even being labeled that the membrane was created to "prevent and/or alleviate contaminant ingress".
