Apple has a new program to address the matter, and the company is facing class-action suits because of it. Luckily, the folks at iFixit were able to obtain an early production model of the 2018 15-inch MacBook Pro and dissected the keyboard.
It was a curious find considering the Apple description of its new MacBook did not mention making any technical changes to the keyboard. But this is Apple we're talking about, so you shouldn't be surprised.
If Apple described the new MacBook Pro's keyboard as one that improves reliability, it would be the same as admitting there were problems with its past keyboards. Only the MacBook Pro with Touch Bar received an upgrade this year, including Intel's latest chips, up to 32GB of RAM, and up to 4GB of SSD storage. During its teardown of the new laptops, iFixit discovered that there might be an ulterior motive in Apple introducing the new keyboard. But apparently, True Tone isn't limited to the colors on the display of the MacBook Pro itself. As of now, Apple has not made any statement regarding the findings that say the MacBook Pro keyboard has been fixed. "This flexible enclosure is quite obviously an ingress-proofing measure to prevent the mechanism from seizing up under the brutal onslaught of microscopic dust", writes iFixit. Besides the fact that the keys have less travel than the keyboards that preceded them and can be annoyingly loud when typing, they are prone to malfunctions or failing completely when dust or crumbs make their way into the butterfly key mechanism. Interestingly, Apple has a patent for this technology, called "Ingress Protection for Keyboards", created to "prevent and/ or alleviate contaminant ingress".
