The iFixit team is still in the middle of tearing down the newest MacBook Pro, but they have stumbled upon an addition that is apparently exciting enough to share in advance: the keyboard’s butterfly switches are now cocooned in a thin, silicone barrier, which may very well be a reliability fix for the heavily publicized dust and sticky-key issues plaguing older models.



This flexible enclosure is quite obviously an ingress-proofing measure to cover up the mechanism from the daily onslaught of microscopic dust. Not — to our eyes — a silencing measure. In fact, Apple has a patent for this exact tech designed to “prevent and/or alleviate contaminant ingress.”
