  3. 昨年モデルの13インチMacBook ProTouch Bar搭載モデルと比較してみましょう。カバーだけで判断すると、これは同じモデルだと言うでしょう。 Appleによるとこの新モデルのバタフライキーボードは若干静かになりましたが、それ以外のアップグレードはありません。両モデルを隣り合わせにしてキーボードを連打してみると、新モデルから出る音はより低音で、カチカチという音が少ないものの、Appleが述べているような違いを見つけることはできません。 もちろん、15インチモデルのキーに関して私たちが以前公表したレポートを読まれた方は、おそらく何が変わったのかご存知でしょう。先を読む必要はありません。これからこのキーを点検していきます。

    • 特に問題なく、バッテリーの接続を外せます。1本のT5トルクスネジで固定されています。ブルーとブラックのPro Tech仕様ドライバーの1本を手に取ります。

    • このモデルのバッテリー容量は58.0 Whで、オリジナル13インチTouch Barの分解モデルに搭載されていた49.2 Whを大きく上回りました。

    • 新モデルのバッテリー容量が増えたのは僅かに肥大したバッテリーがその要因です。前モデルに搭載されていたバッテリーセルの数は5つであったのに対し、新モデルは6つです。 そしてこのバッテリーセルの重量は232.7 gで、旧モデルのバッテリー196.7 gと比べて随分と増量しました。

    • しかしながら、このMacBook Proの総重量は、前モデルと比べてわずかな違いもありません。このデバイスのどの部分でダイエットが行われたのかはわかりませんが、Appleが上部ケースの大部分を削ぎ落としたようです。

    • それにもかかわらず、Appleによるとバッテリーの寿命は依然として従来モデルと同じとしています。 これらの追加されたプロセッサコアはタダではついてこないのです。

    • 新しく改善されたスピーカー(画像右側)も大きくなりました。より細長くなり、余分スペースを最大限活用しており、上部ケースのデザインが変更されたため、ロジックボードに重なっています。

    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.

    Could you show us visually the difference if you’ve spotted it?

    Kenneth - 返信

    @vipersonic We haven’t done a comprehensive comparison, but I can tell you one or two things off the top of my head. Take a look at this image and note the thin divider separating the logic board from the battery/speaker area. On the old model at left, the divider is thicker and extends all the way to the edge of the case. In the new model it’s not only thinner and smaller, but Apple has carefully hollowed out large holes all along its length. (You can’t see the holes in the photo, but they’re very obvious with the components removed.) I’d guess they removed roughly half the mass from that inconspicuous little strip of aluminum.

    Jeff Suovanen -

    Am I correct that in order to swap the battery, the logic board needs to be completely take out unlike the new MacBook Air 2018? I can’t find a single video of complete MacBook Pro 13-inch 2018 disassembly and/or full steps to replace the battery.

    Phillip Rosenthal - 返信

    Looks like one of the Thunderbolt ports on the right-hand side, probably the one closest to the headphone jack, is connected to the T2 by way of a USB switch. This is probably the port that is used to perform a DFU restore of the iBridge, like on the iMac Pro ( https://help.apple.com/configurator/mac/... ) It’s possible that data recovery could also be performed via that Thunderbolt port given the right tools.

    repoman27 - 返信

    Nah. The MacBook Pro is becoming like iOS devices: outside of backups, nothing will be recoverable.

    Given the T2, having a service port or a Thunderbolt port form which data can be extracted would amount to having a backdoor.

    @shamino No. The port on the right side of the fan screwed down by a metal plate is a port where a flex cable to the Touch Bar is connected to. The Touch Bar has two cables, one that sends input to the logicboard, and another that sends display signals and power to the Touch Bar.

    You’re confusing Secure Element and Secure Enclave. The Secure Element is used to store Apple Pay information whereas the Secure Enclave is used to store cryptographic keys and is part of the A, T or S series chip (e.g. A12, T2, S2). What’s on the picture is the Secure Element. You can read about both on Apple’s iOS Security Guide (https://www.apple.com/business/docs/iOS_...)

    @Karl B I’m guessing it’s to assist with continuity features. Like if you’re wearing an Apple Watch, you can just sit down at your MacBook Pro and it will unlock for you. https://support.apple.com/en-us/ht204681 I believe this also works via Bluetooth by calculating time of flight, but NFC is probably easier / more secure.

    That “foam rubber” you are referring to is most likely silicone rubber. Silicone rubber is a type of potting compound that forms a gel-like substance once set. This substance serves as a non-conductive material that helps fix electronic components on a circuit board in place and has the added benefit of impact resistance and moisture resistance. Silicone rubber compounds can also be rated to various levels of fire retardant properties as well. This compound is commonly found in power supplies and can be referred to as “silastic” compound, which is a trademark held by Dow Corning.

    Depends on how important it is to you and also your level of risk tolerance. If you’re experienced and confident in your ability to do this without damaging anything, sure, go for it. I personally hesitate to ‘‘‘recommend’’’ doing something like that on a brand-new machine that’s still under warranty, especially given that the throttling reports have been a bit inconsistent—if it’s as bad as some people say, an improved application of thermal paste is unlikely to make much difference. Might want to wait a bit and see how things shake out.

RAID 0 SSD? From Samsung?

Peter Gamble - 返信

Hi Peter,

The “SSD”/flash memory is made by Toshiba.

Arthur Shi -

Not in this series.

Keep in mind the T2 is a flash controller, so Apple is side stepping the PCIe/NVMe issue of the SSD instead using raw flash chips which are interleaved simular to how memory is done. The T2 presents the PCIe/NVMe interface to rest of the system.

In truth it’s like RAID, but it’s not! It’s something newer! As it’s soldered to the logic board Apple can get away with this.

Dan -

To elaborate on what Dan said, the T2 chip includes Apple’s own NVMe PCIe SSD controller, which they developed in house. Like most SSD controllers, it uses multiple channels (maybe 8 in this case?) to address the NAND flash dies and increase performance through parallelism. Both the T2 and the NAND flash packages are soldered directly to the logic board. It is also likely that the drive can tolerate the failure of individual blocks and pages, or perhaps even whole NAND dies by using parity data.

This is a different concept than RAID though, which employs Redundant Arrays of Independent Drives to increase availability and in some cases performance. RAID 0 in particular ditches the redundant bit and stripes across an array of independent drives purely for increased performance. Apple decided to put the NAND flash packages for the iMac Pro on a pair of removable modules, however they were in no way independent drives. There was still only a single SSD controller located in the T2 chip on the logic board.

repoman27 -

The T2 processor should not be NAND Flash controller here. T2 is more like a RAID controller. Refer to https://duo.com/blog/apple-imac-pro-and-... The Toshiba chip here could be a PCIe/NVMe SSD in BGA chip package(like the one in the iPhone/iPad). The physical interface between T2 and Toshiba chip could be PCIe interface. T2 processor is also used to replace TI’s SMC controller.

JJ Wu -

@JJ Wu, The SSD controller is in the T2. To quote Apple: “Introducing the Apple T2 chip, our second-generation custom Mac silicon. By redesigning and integrating several controllers found in other Mac systems — like the system management controller, image signal processor, audio controller, and SSD controller — T2 delivers new capabilities to the Mac.”

The notion that the iMac Pro used independent drives in RAID 0 is a widely held misconception that is entirely inaccurate. Look at the packages on the modules. They are commodity multi-chip NAND packages that connect to the SSD controller in the T2 using a typical NAND bus architecture. This is essentially the same SSD as in the iMac Pro but the NAND packages are on the logic board instead of on independent modules.

repoman27 -

@repoman27  i talked to Apple store employee. The SSD module used in the Apple iMac Pro can be replaced by other PCIe SSD(Apple does not recommend doing that) and the employee said it is PCIe interface which means it can not be typical NAND interface.

This is an example of BGA SSD on M.2 module https://www.anandtech.com/show/12819/the...

JJ Wu -

@JJ Wu The SSD in the iMac, Mac Pro, MacBook Air, and MacBook Pro (Late 2013 - 2015) is a PCIe SSD with a proprietary form factor and connector. If you have installed macOS 10.13 High Sierra or later, the firmware will be updated to unofficially support 3rd party NVMe PCIe SSDs. Then you can use an adapter to physically convert from Apple’s proprietary interface to M.2 2280 or whatever and replace the drive. Third party solutions emulating Apple’s form factor and connector are also available for these models.

That is not at all the case for the *iMac Pro*. No adapter exists because the NAND flash modules are not independent drives and are not connected to the T2 via PCIe. Look at the iFixit teardown of the iMac Pro. Try searching for an adapter or third party SSD upgrade solution. You will not find one.

repoman27 -

Data recovery from a failed logic board is probably handled by the T2 chip, since it serves as the flash controller. If the T2 chip is toasted, the contents of the flash memory are probably beyond recovery, since the T2 almost certainly uses a hardware key as part of the encryption scheme. No idea about how service techs would communicate with the T2 on an otherwise failed board. Maybe via an existing bus connector?

Intel JHL7540 Thunderbolt 3 Controller? The new Titan Ridge controller? Does that mean these MacBook Pros support DisplayPort 1.4?

Razvan Dudas - 返信

Wow, new TB3 controller, really? Does that mean these 13-inch notebooks now have full-speed on all four TB3 ports?

Faberge Fabulous -

That was already confirmed, yes. The new 13-inch MacBooks have full-speed on all four TB3 ports (as fas as I know, the previous generation didn’t not because of the controllers, but because the Intel CPU itself only had 12 PCIe lanes, which weren’t enough to have full-speed on all 4 ports). But I haven’t seen the DisplayPort 1.4 support mentioned anywhere, which is why I presumed that Apple didn’t update the controllers to the Titan Ridge generation.

Razvan Dudas -

Ok, it seems I was too optimistic. According to Anandtech:

It's also worth noting that since the DP 1.4 spec is not supported by Intel's iGPUs, Intel-powered notebooks and desktops looking to take advantage of Titan Ridge's DP 1.4 functionality will have to use dGPUs to drive their TB3 controllers. This will somewhat increase the complexity of these designs, since previously most vendors only needed to route the iGPU to the TB3 controllers.

So it's certain that the 13-inch MacBook Pro does not actually support DisplayPort 1.4, because the integrated Intel GPU does not support it (and you cannot add a dGPU to the 13-inch MacBook Pro). As for the 15-inch MacBook Pro, it remains a possibility, but I don't think that Apple did in fact decide to use the dGPU to drive the Titan Ridge controller, which means that the 15-inch MacBook Pro doesn't support it either, I presume.

Razvan Dudas -

External displays are always driven by the discrete GPU on the 15-inch, so there is still hope there. I believe the internal display is connected to the Intel integrated GPU via eDP to allow graphics switching, but 4 DisplayPort main links from the AMD GPU feed the two Thunderbolt controllers.

repoman27 -

Any ETA on the 15” 2018 model teardown? Specifically, I’m wondering if the SSD on the 15” is soldered as well! If it’s non-upgradeable SSD like this 13”, then I need to invest in higher storage to last me over the years but I’d definitely prefer not to have to if possible! I hate how these beautiful machines are becoming less and less upgradeable.

helio - 返信

Hi Helio,

The “SSD” on the 15 inch follows the same setup: flash memory chips soldered onto the motherboard, with the T2 chip acting as the controller.

Ming - 返信

The Apple/Universal Scientific Industrial (USI) 339S00428 Wi-Fi/Bluetooth module is the same chip used in the iMac Pro. The iMac Pro specs out Bluetooth 4.2. The 2018 MPB has Bluetooth 5.0. The chip is clearly capable of a software upgrade. Apple/USI have been very secretive about this chip. The Pro designation means that creatives would be using their computers requiring increased throughput in dense user environments. High-Efficiency Wireless (HEW), IEEE 802.11ax provides 4x throughput in these environments which will be widely available in 2019 before the next yearly upgrade. Broadcom, Qualcomm, Marvell and Quantenna currently all have 802.11ax chips which Apple passed over. 802.11ax has the same antenna matrix as 802.11ac so the 2018 MPB can accommodate 802.11ac. Is the USI 339S00428 Wi-Fi/Bluetooth module upgradeable to 802.11ax (like MBP chips supporting 802.11g were surprisingly able to upgrade to 802.11n)?

Malibu Art - 返信

How many spatial streams are supported on 802.11ac? 3 or 4?

Raoul H -

Newer specs often adopt and standardize features that already existed as proprietary extensions to the previous version. Thus a quick firmware or driver update can bump up the revision number because some of those features were already supported by the silicon. (e.g. 802.11a/b/g hardware that included “draft n” features could become 802.11a/b/g/n via a software “enabler”. ) That appears to be the case with this USI module and Bluetooth 4.2 > 5.

It is incredibly unlikely that this module contains certain functionality necessary to implement the more compelling aspects of 802.11ax. In particular, OFDMA isn’t something that can just be bolted on via a firmware update.

Apple’s use of 3x3:3 Wi-Fi modules in MacBook Pros already makes them 50% faster than any integrated laptop solution from other vendors.

@Raoul H, 4 spatial streams are supported under 802.11ac, but usually only by access points. Apple is the only OEM I am aware of to ship a laptop with support for more than 2 spatial streams.

(e.g. 802.11a/b/g hardware that included “draft n” features could become 802.11a/b/g/n via a software “enabler”. ) That appears to be the case with this USI module and Bluetooth 4.2 > 5.

It is incredibly unlikely that this module contains certain functionality necessary to implement the more compelling aspects of 802.11ax. In particular, OFDMA isn’t something that can just be bolted on via a firmware update.

The question is whether the silicon already supports 802.11ax which can be accessed through a software upgrade just like Bluetooth 5.0.. Apple is already part of the consortium of manufacturers supporting Draft 3.0 of 802.11ax. Most OEMs have chips now and will release hardware this year in time for the holiday season. Why wouldn’t Apple/USI reward its Pro lines with the shiniest new silicon for a Pro environment next to a six-core CPU?

Do you mind reviewing my question regarding the MBP 2018 vs. 2017 Power Adapter? Interesting issue I discovered, not sure if it’s something well known. Eager to hear any/all thoughts.

Here’s the link: Difference Between 13" MacBook Pro 2018 and 2017 Power Adapters

Thanks!

It's the new charger got any different with the voltage or something?

I’d reckon it’s a complete redesign to be (more) compliant with the latest USB Power Delivery Specification Rev. 3.0, Version 1.2. That might have ramifications for charging iOS devices from these newer power adapters. AFAIK, Apple’s proprietary divider methods are no longer allowed, and to get certification, chargers must provide power according to the USB Battery Charging 1.2 spec instead.

I imagine this model also supports all of the normative voltage and current levels expected of a 60W USB Type-C charger according to the latest specs. So it probably provides better interoperability with non-Apple devices.

It may also include a programmable power supply. Hopefully someone manages to coax Benson Leung or Nathan K. into doing a little write-up on this.

Why isn’t it possible to install the new keyboards with the protective membranes to the 2027 MBPs?

I’m curious about this second generation T2 chip. Most folks never noticed, but an early generation of the Intel based MBP, I believe the (1,2) and/or (1,3) laptops produced in 2007 or so, also included the T2. It prevented non-blessed systems (i.e., Linux) from being installed. Only OSX and blessed MS Windows systems would work with those boxes. The only folks who noticed were those who tried to install Linux via rEFInd and a few other documented methods for modifying Apple’s UEFI. I still own a MBP (1,1) which I bought in 2006, and which has been running Linux ever since Apple discontinued OSX system updates. A friend acquired a (1,2) and was absolutely unable to use rEFInd as I had done for an install. With investigations and inquiries on the network, we discovered the T2 chip had been the problem. It looks like Apple again wants to “secure” its hardware from third party (Linux, Unix) OS installations.

I have an early 2008 MBP, and it is very picky about booting Linux. I too have wasted many an hour messing around with various distros and bootloaders only to wind up frustrated. However, AFAICT it is due to the NVIDIA dGPU and chipset, not an evil plot by Apple. I recently booted Ubuntu 18.04 Bionic Beaver from a USB thumb drive successfully by simply adding the nomodeset boot option. You may want to give it a try if you’ve still got that hardware kicking around.

But I can pretty much guarantee that if there is a chip called T2 in the MBPs from that era, it shares absolutely no lineage with the current T2.

The hottest laptop of the year.

Is there a guide anywhere here or on the web on a screen/LCD replacement? I’m not sure if this is possible, and if it is, if the part would be available to the general public this early.

GP16 - 返信

it’s pretty much the same as a 2017 LCD assembly, the internal Apple guides for both year models are the same, I just checked

rnikkel -

So the display assembly with previous models is compatible?

What is the clearance/distance between the heatsink and the bottom cover? I want to know to put the right thickness of thermal pads in between the two to transfer heat more effectively..

I just bought a 2018 15” MacBook Pro. But I opted for the lowest configuration of the highest tier. Mainly because I specifically asked the guy at the Apple store if I can upgrade the RAM and SSD later. He said I could. Is it really not possible to upgrade the SSD?

As the RAM and “SSD” are now chips soldered onto the motherboard (see steps 9 & 10), upgrading will unfortunately look like turning in your MacBook for a new one.

Arthur Shi -

You could opt for external storage, but I wouldn’t consider that a true upgrade, and there’s no recourse for RAM at all.

Are any of the removable components secured by tape? The guide only lists Torx screws for fasteners.

Buonasera, io ho questo modello e stavo prendendo in considerazione l’idea di migliorarne le prestazioni, dato che per il lavoro che svolgo non sono sufficienti (mi occupo principalmente di video editing e motion graphic design)… Volevo chiedervi quindi, per migliorare le prestazioni di questo mac, è consigliabile sostituire fisicamente RAM e SSD? O è meglio acquistare un mac più prestante?

Grazie anticipatamente,

bell’articolo!
