hey guys we're in the middle of our
teardown of the new 15-inch MacBook Pro
and we stumbled onto something
interesting we had to stop and show you
so yesterday
Apple announced the new MacBook Pros
they've got upgraded processors true
tone display and a quieter keyboard but
they made no mention of a design change
to the problematic butterfly mechanism
used underneath the keys if you haven't
heard about all these issues we've got a
video that'll get you up to speed on all
the problems people have been having and
our theory on why a tiny speck of dust
can cause these keyboard failures but
here's the TLDR
apple's retina macbook sand macbook pro
keyboard design allows dust and debris
to get into the keyboard we even tested
it out and showed you how a tiny piece
of dirt can prevent the key from being
depressed to fix it
you'd have to replace the entire upper
case of the computer not fun that brings
us to today where we discovered
something different and cool take a look
under this key not much has changed
structurally with the keys we've still
got the large dome button and the
butterfly mechanism looks relatively
unchanged but here's where we've got the
big update as you can see Apple has
added the thin skin that quite obviously
acts as ingress protection around the
mechanism preventing dust from getting
inside in fact Apple has a patent for
this exact tech to prevent and/or
alleviate contaminant ingress this
patent describes a membrane that covers
the key mechanism specifically
preventing interference from dust or
liquid so maybe Apple's new quieter
keyboard is actually a conspiracy to fix
their keyboard reliability issues or
maybe clack e keys are actually a
problem either way this plastic film
seems like a band-aid of a fix we also
don't know with people who are using
Apple's keyboard replacement program
we'll be getting these new keyboards but
we hope to find out and we'll have the
full teardown of these MacBook Pros
coming soon
