The 13" MacBook Pro has received the Retina display treatment! Let's see what it's packing.

• 13.3" 2560x1600 pixel (227 ppi) Retina display
• 2.5 GHz Intel Core i5 processor
• 128 or 256 GB flash storage
• 8 GB DDR3L onboard RAM
• Thunderbolt, USB 3.0, and HDMI I/O
• Intel HD Graphics 4000

We normally charge top dollar for pictures of kittens, but today you can have these wallpapers for the low, low price of $free. They're the right resolution (aka 2560 x 1600) for your 13" MBP con Retina Display.

Devices from bottom to top:

• 13" MacBook Pro Early 2011
• 13" MacBook Pro Retina Late 2012
• 21-Day-Old Kitten Late 2012

This Retina MacBook Pro has the model number A1425. Does that model number look unfamiliar to you? Us too!

• Another new MacBook Pro Model number?! We haven't been this excited since the last time Apple gave out a new model number to Big Brother Retina.

Enough with the completely redesigned outside…let's get inside!

We open it up to find…

• …a grumpy face?

It's a familiar face, though it seems to be missing some teeth. There is definitely a battery design change, specifically the migration of two battery cells off of the trackpad. We will examine this more later, but it appears that the trackpad will be a little easier to replace this time around.

Grumpy kitten glares back at the grumpy-faced MacBook Pro Retina, likely reminiscing on Retina displays past.

Service only by an Apple Cert— ya, we've seen it again, and again, and again.

• Just as we've said time after time, we have the right to remove 'Do Not Remove' stickers.

As always, we start by disconnecting the battery, a simple task that requires no more than releasing a conn—wait, what is this?

Instead of the good ol' run-of-the-mill battery connector that we've seen in most other Apple laptops, the battery is connected using several screws that hold a connector board in place.

This little PCB serves only as a bridge between the battery control board and the logic board.

• …weird?

At first we thought we found some kitten fuzz, but it turns out that Apple glued in a small piece of steel-wool-like metal on top of two of the speaker screws.

Why, you ask?

We don't know, but we have some hypotheses:

• Grounding?
• Noise reduction?
• Tamper-evident seals?

The most striking layout change resulting from the shrink from a 15" to 13" form factor is the rearranged battery cells. This allowed Apple's designers to cleverly tuck the SSD away underneath the trackpad assembly.

The empty space next to the SSD is very un-Apple. It's not like them to leave big air gaps in their newest, sleekest designs.

Our first thought was that a standard 2.5" laptop drive might fit in this space, and it almost looks like this little nook was designed with that in mind.

• Our 9.5mm Crucial SSD didn't allow the bottom cover to be closed, but just by a smidge. We'll see if a 7 mm or 5 mm super-slim hard drive could be incorporated into the space.
