Here’s an inflammatory take for you: Apple’s new quieter keyboard is actually a silent scheme to fix their keyboard reliability issues. We’re in the middle of tearing down the newest MacBook Pro, but we’re too excited to hold this particular bit of news back:
Apple has cocooned their butterfly switches in a thin, silicone barrier.
This is a promising discovery.
The biggest lingering question for me is whether this keyboard is being swapped into repaired 2016 and 2017 MacBook Pros. If you get your MacBook Pro keyboard repaired over the next couple of months and notice any changes, let me know.
Update: Joe Rossingol, MacRumors:
When asked if Apple Stores and Apple Authorized Service Providers will be permitted to replace second-generation keyboards on 2016 and 2017 MacBook Pro models with the new third-generation keyboards, if necessary, Apple said, no, the third-generation keyboards are exclusive to the 2018 MacBook Pro.
I hope there’s a purely technical reason for this decision.
