Introduction
A year after release, Apple just announced its first update to the 12" MacBook with Retina Display. It's sort of a baby update, so we decided to match it with a baby teardown. Besides a faster processor and zippier flash memory, what changed? There's only one way to know: crack it open and spill its secrets. Join us for a mini-teardown of the Retina MacBook 2016.
For a no-holds-barred disassembly of the initial Retina MacBook release, check out our Retina MacBook 2015 teardown.

With the MacBook jumping on the Rose Gold bandwagon, who knows what's lurking inside? Here's the lowdown so far:
-
12-inch 2304 × 1440 (226 ppi) IPS Retina Display
-
1.1 GHz dual-core Intel Core m3 processor (configurable up to 1.3 GHz dual-core Intel Core m7)
-
8 GB of 1866 MHz LPDDR3 RAM
-
256 or 512 GB PCIe-based flash storage
-
Intel HD Graphics 515
-
802.11a/b/g/n/ac Wi-Fi wireless networking and Bluetooth 4.0
-
Single USB-C port and 3.5 mm headphone jack
-
-
-
If it weren't for the rose gold finish, we'd be hard-pressed to distinguish between this year's Retina MacBook, and the one of yesteryear.
-
The exteriors look identical, from the Pentalobe screws in the lower case all the way down to the model number—A1534.
-
-
-
Popping the hood on this MacBook gives us an indication that the rose gold beauty is much more than skin deep.
-
Before delving any deeper into this beauty, we take a quick look at the chips powering the trackpad:
-
Broadcom BCM5976 Touchscreen Controller
-
STMicroelectronics 32F103 ARM Cortex-M3 Microcontroller
-
International Rectifier IRFH3702 Single N-Channel HEXFET Power MOSFET
-
-
-
-
What's that? The pesky tri-wing screw we saw last year grew another, um, wing—now it's a regular ol' repair-friendly Phillips.
-
Thankfully, all the other internal screws remain standard Phillips and Torx screws.
-
-
-
And at the other end of the MacBook, it seems the USB-C hardware has also changed. The cable is now perma-fixed to the USB board, condensing the two components into a single unit.
-
...Also, the silicon is new and moved from the cable itself to the USB board. Here's a comparison of the new USB-C hardware (top) with that of the 2015 Retina MacBook (bottom).
-
Parade Technologies PS8741A (likely an iteration of the PS8740 USB Type-C Redriving Switch)
-
-
-
The battery's form factor seems 100% identical to the multi-lobed cell we found in the 2015 Macbook.
-
And yet somehow, Apple managed to squeeze in a 4% capacity increase from the 7.55 V, 39.71 Wh battery in last year's model. Apple claims this new 7.56 V, 41.41 Wh Li-ion power source should provide up to 11 hours of iTunes movie playback.
-
Unfortunately, they did not squeeze in any of those nifty adhesive pull tabs we've seen in Apple's iDevices.
-
-
-
Logic Board! What chips is this MacBook serving up?
-
Intel SR2EN Intel Core m3-6Y30 Processor (4M Cache, up to 2.20 GHz)
-
Toshiba TH58TFT0DFKLAVF 128 GB MLC NAND Flash (+ 128 GB on the reverse side for a total of 256 GB)
-
Micron MT41K256M16LY-107 4Gb DDR3L SDRAM
-
Universal Scientific Industrial 339S0250 Wi-Fi Module
-
Broadcom BCM15700A2 (as seen in several other MacBook models)
-
National Semiconductor 48B1-11
-
F4432ACPE-GD-F (with SSD controller presumably layered underneath)
-
-
-
But wait, there's even more chips on the back:
-
Toshiba TH58TFT0DFKLAVF 128 GB MLC NAND Flash
-
Samsung K3QF4F4 4 GB LPDDR3 RAM (x2, for a total of 8 GB)
-
Apple 338S00066
-
Texas Instruments/Stellaris LM4FS1EH SMC Controller (Replacement codename for TM4EA231)
-
SMSC 1704-2 Temperature Sensor
-
Texas Instruments SN650839, TPS51980A, and CD3215B01
-
Intersil 95828

Retina Macbook 2016 Repairability Score: 1 out of 10 (10 is the easiest to repair)
-
Those pesky tri-wing screws are gone, replaced with lovely standard Phillips screws—but tamper-evident hinge screws make you feel like a hoodlum for repairing your own machine.
-
The processor, RAM, and flash memory are still soldered to the logic board.
-
The battery assembly remains entirely, and very solidly, glued into the lower case.
-
The Retina display is still a fused unit with no separate, protective glass. If the display needs replacing, it'll cost a pretty penny.
