MacBook Pro 13" Touch Bar 2018 Teardown
By Adam O'Camb • Difficulty: Moderate

Apple has been quietly improving their pro-level laptops, making them … quieter. Turns out they’ve improved the clacky keyboards more than they’ve let on—which leaves us wondering, what else is new in here? All we need is a teardown team and several thousand US greenbacks to find out. Grab your best tinkering tools and let’s dig in—we’re tearing down the 13” MacBook Pro with Touch Bar, 2018 edition.

Step 1
  • Before we put this one under the knife, let's review what we exspec to find:
  • 13.3" LED-backlit IPS Retina display with True Tone, 2560 x 1600 resolution (227 dpi), P3 wide color gamut
  • 2.3 GHz quad-core Intel Core i5 (Turbo Boost up to 3.8 GHz) with integrated Intel Iris Plus Graphics 655
  • Apple T2 custom coprocessor
  • 8 GB of 2133 MHz LPDDR3 SDRAM
  • 256 GB PCIe-based SSD
  • 802.11ac Wi-Fi and Bluetooth 5.0
  • Four Thunderbolt 3 (USB-C) ports supporting charging, DisplayPort, Thunderbolt, USB 3.1 Gen 2
Step 2
  • Spoiler alert! As always, we like to start off with a superhero's-eye-view of our victim's internals.
  • These X-ray images come to you thanks to our ingenious pals at Creative Electron.
  • Don't worry, we're still going to take it apart. Hold that thought ...
Step 3
Step 4
  • Our teardown begins in earnest—we dispatch a sextuplet of pentalobe screws, and dash through what by now is a pretty familiar opening procedure.
  • At first glance, the internals look very similar to the 13" MacBook Pro from last year ... and the year before that.
  • At second glance, we decide to go in closer for a third glance.
Step 5
  • We disconnect the battery without any drama—it's buttoned down with a T5 Torx screw, so we use one of our blue and black Pro Tech specialty drivers to dispatch it.
  • At 58.0 Wh, this battery has gotten a significant boost over the 49.2 Wh unit we found in our original 13" Touch Bar teardown.
  • Turns out that extra 'oomph' comes from a slightly bigger battery—arrayed into six cells this time, instead of five. It's also heavier, weighing in at in at 232.7 g, versus the old battery's 196.7 g.
  • And yet this MacBook Pro's total weight hasn't changed one iota. We're not sure which parts of this device have been on a diet, but it does look like Apple shaved some mass off the top case.
  • Despite all that, Apple still rates battery life the same as the prior model. Those extra processor cores don't come for free.
  • The new-and-improved speakers (on the right) have grown, too—they're longer and narrower, filling all the remaining space, and bumping right up against the logic board thanks to the revised top case design.
Step 6
  • In a lone piece of happy repair news: the trackpad is replaceable as ever. Twirl away a few Torx screws, and off it flies.
  • We get our first taste of some chips under the trackpad (looking virtually unchanged from their first outing back in 2016):
  • STMicroelectronics STM32F103VB ARM Cortex-M3 MCU
  • Broadcom BCM5976C1KUFBG Touch Controller
  • Maxim Integrated MAX11291ENX 24-Bit, 6-Channel Delta-Sigma ADC
  • Meanwhile, we can't help but notice the earlier model's port to nowhere—which turned out to be for data recovery—is mysteriously absent.
  • Given this MacBook's non-removable storage, Apple must have a new recovery method?
  • Update: They didn't—until they did.
Step 7
  • Apple was careful to mention its latest third-gen keyboard in its press release. The added quietness seems a bit underwhelming to our ears, and we suspect there's something more going on.
  • After three years of key-cap removal, we're able to pop this lid open without damaging the delicate clips, and boy are we rewarded.
  • As you may have heard, there's a brand new silicone barrier under here.
  • Apple says this new addition is purely for soundproofing, but it bears a suspicious resemblance to their 2016 ingress-proofing patent—one that might help prevent the keyboard failures we keep hearing about.
  • This bears further analysis. We'll have a deeper dive on the keyboard situation later in the week. Stay tuned!
Step 8
  • Time to liberate that logic board and look around!
  • As usual, a relatively modest-looking heat sink handles cooling for the CPU and integrated graphics. Another par for the course: Apple's typical glut of thermal paste.
  • And our first peep of silicon reveals: the touted T2!
  • Seen previously in the iMac Pro, Apple's custom T2 chip has taken over an impressive number of functions—but, we still expect to find a lot of other silicon on this board. Let's check it out!
Step 9
  • Here's a familiar mustache full of chips:
  • 8th-generation Intel Core i5-8259U CPU with Intel Iris Plus Graphics 655
  • Apple T2 APL1027 339S00533 coprocessor, layered over 1 GB Micron D9VLN LPDDR4
  • Toshiba TSB 3226 J86404 TWNA1 (likely 2x 64 GB flash memory, 128 GB total on this side)
  • 4x SKhynix H9CCNNNBJTAL 16 Gb LPDDR3 2133 MHz (8 GB total)
  • Intel JHL7540 Thunderbolt 3 Controller
  • Apple/Universal Scientific Industrial (USI) 339S00428 Wi-Fi/Bluetooth module
  • 338S00267-A0 (likely Apple PMIC)
Step 10
  • And we flip it around for some bonus silicon:
  • 2x Toshiba TSB 3226 J86404 TWNA1 64 GB flash memory, for 128 GB on this side and 256 GB total)
  • 2x Texas Instruments CD3215C00 83CFZST
  • Cirrus Logic CS42L83A Audio Codec
  • Intersil 95828A HRTZ X813HNK
  • 2x NXP 6142F
  • Texas Instruments TPS51980A synchronous buck controller
  • NXP 80V18 secure NFC module
Step 11
  • And for our dessert course we have: a brand new USB-C power adapter!
  • The A/C adapter included with this 13" MacBook Pro does indeed sport the new model number A1947 (vs. A1718, bottom), so it's time to bust out the ultrasonic cutter and go to town.
  • After clawing painfully through more layers and rubberized filler than we've ever seen in one of these things, we finally free the internals.
  • Opening the previous adapter (on the left) was a walk in the park compared to this unit, but it does look like this model benefits from redesigned internals, some additional shielding, and lots of impact-resistant foam rubber.
  • That said, Apple has also swapped the aluminum USB-C port for a plastic one ...
Step 12
  • Here's what's left after the 2018 MacBook Pro gave up its secrets, including:
  • A bigger battery that squeezed the speakers into a narrower form factor.
  • A keyboard decked out with a thin silicone barrier, which could be for sound baffling, but matches Apple ingress-proofing patents.
  • And a seemingly unchanged thermal management system, despite the extra power under the hood.
  • Teardown Update: we wanted to drill a bit deeper into the new keyboard, so we did some testing and then gave it another teardown all to itself. Check it out!
  • And if we missed something, check out our teardowns of the 2016 and 2017 models—you may well find it there!
Final Thoughts
  • The 2018 MacBook Pro 13" with Touch Bar earns a 1 out of 10 on our repairability scale (10 is easiest to repair):
  • The trackpad can be removed without first removing the battery.
  • The processor, RAM, and flash memory are soldered to the logic board. Repairs and upgrades will be impractical at best.
  • The top case assembly, which includes the keyboard, battery, and speakers, is glued together—making all those components impractical to replace separately.
  • The Touch ID sensor doubles as the power switch, and is paired with the T2 chip on the logic board. Fixing a broken power switch may require help from Apple, or a new logic board.
