The new MacBook
is the result of a collective obsession
to simplify its essential components
to create the most efficient design possible.
It's a product that couldn't exist
without invention across many disciplines.
A full-size keyboard is the most familiar,
comfortable, and accurate typing platform.
It defined the width of the new MacBook.
To make it thinner and more precise,
we created a sturdy,
single-assembly butterfly mechanism.
Combined with a new stainless steel dome switch,
this reinforces the keyboard's balance and stability.
Each individual key is now lit by a single LED.
This enables better, more deliberate illumination.

A Retina display delivers
the very best viewing experience.
To engineer the thinnest Retina screen for a Mac,
we've refined every component --
from the glass down to the pixels.
It delivers the vivid brightness and performance you'd expect,
but in a design that's thinner, lighter,
and 30% more power efficient.
We've designed a force-sensing, multi-touch track pad.
This adds a new dimension of interaction.
Touch sensors make the entire glass surface active.
Force sensors measure a wide range of pressure --
from the lightest tap to the deepest press.
The pressure you apply activates an electromagnet
that responds with tactile feedback.
So now instead of just seeing what's happening on the screen,
you feel it, too.

To make all-day battery life possible,
we have developed new battery technologies.
We actually changed the construction
and internal chemistry of the cells,
which are now manufactured in discrete sheets.
These sheets are stacked in a terrace structure
that was developed along with the external enclosure.
The design allows for 35% greater battery capacity
in this compact space.
To maximize performance,
we took an extreme approach to miniaturization.
Components were optimized and engineered to fit together
to create the highest-density Mac logic board yet.
It's actually two-thirds smaller
than any we've designed before.
A fundamental goal was to eliminate the need for vents,
fans, or any moving parts --
allowing it to operate in silence.
By consolidating the antenna with the bottom case,
we were able to design an integrated aluminum hinge.
This innovation --
along with its unibody enclosure --
makes this the first all-metal MacBook.

This product is not only thin and light,
its advanced wireless technologies
make it truly portable.
When you actually need to plug in,
the new USB Type-C connector is a single port
for charging, video output, and data transfer.
The result of all of this
is a product that's only 13.1 mm thick
and weighs just two pounds.

To create the new MacBook,
we were uncompromising in its design and engineering.
We set a new standard for portability,
while enhancing its fundamental components.
To deliver, what we believe,
is the best MacBook yet.
