When Apple announced the new MacBook Pros a few days ago, it revealed to several publications that the third-generation butterfly keyboard is not designed to solve the reliability issues that plagued previous models. However, iFixit's teardown of the keyboard suggests otherwise.
According to iFixit's teardown which is still underway, the quieter keyboard which Apple touts as an improvement is actually a silent move to fix the reliability issues. Apparently, Apple has "coooned" the butterfly switches in a thin, silicone membrane. iFixit believes it is "an ingress-proofing measure" to protect against dust. To support its claims, iFixit highlighted that Apple has a patent for the same exact design which is designed to "prevent and/or alleviate contaminant ingress".
