Introduzione

Apple si è messa silenziosamente al lavoro per migliorare i suoi laptop di livello pro, rendendoli... più silenziosi. Risulta che abbiano migliorato le sue rumorose tastiere più di quanto abbiano fatto trapelare, cosa che porta a chiederci: che cos'altro c'è di nuovo? Tutto quel che ci serve per scoprirlo è una squadra di smontaggio e diverse migliaia di verdoni, leggi dollari. Prendi i tuoi migliori attrezzi e lanciamoci insieme nell'operazione: stiamo per smontare il MacBook Pro Touch Bar da 13" nella versione 2018.

    • Il nostro smontaggio inizia sul serio: facciamo fuori un sestetto di viti pentalobe, passando per quella che ormai è una procedura di apertura molto familiare.

    • In base a una prima occhiata, le pareti interni sembrano molto simili a quelle del MacBook Pro dell'anno scorso... e dell'anno ancora precedente.

    • Dopo una seconda occhiata, decidiamo di guardare più da vicino e dare una terza occhiata.

    • Disconnettiamo la batteria senza problemi: è tenuta giù da una vite Torx T5, quindi usiamo uno dei nostri Cacciaviti Pro Tech Specialty per averne facilmente ragione.

    • Con i suoi 58,0 Wh, questa batteria è parecchio più prestante di quella da 49,2 Wh che avevamo trovato nello smontaggio del nostro 13" Touch Bar originale.

    • Si scopre che questa botta di energia in più è ottenuta con una batteria un filo più grande, questa volta in configurazione a 6 celle invece di 5. E' anche più pesante: 232,7 grammi contro i 196,7 della vecchia batteria.

      • Ma il peso totale di questo MacBook Pro non è cambiato di una virgola. Non sappiamo con certezza quali parti siano state messe a dieta, ma sembra che Apple abbia tolto un po' di massa al case superiore.

    • Nonostante l'aggiornamento, Apple dichiara un'autonomia pari a quella del vecchio modello. Questi extra processori non sono gratis.

    • Anche gli altoparlanti nuovi-e-migliorati (a destra) sono cresciuti: sono più lunghi e stretti per riempire tutto lo spazio rimasto e sono posizionati contro la scheda logica grazie al nuovo design del case superiore.

    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 - Replica

    @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 -

    • Un pezzo unico, in tema di riparazioni felici: il trackpad è sostituibile come sempre. Fate girare alcune viti Torx e verrà via subito.

    • Un primo assaggio dei chip lo troviamo sotto il trackpad (il tutto appare virtualmente invariato rispetto alla prima uscita del 2016):

      • MCU Cortex-M3 ARM STMicroelectronics STM32F103VB

      • Controller Touch Broadcom BCM5976C1KUFBG

      • ADC Delta-Sigma a 6 canali e 24 bit Maxim Integrated MAX11291ENX

    • Nel frattempo, non possiamo non notare che la porta verso il nulla - che si è poi scoperto serviva al recupero dati - del modello precedente è misteriosamente assente.

      • Dato che questo MacBook ha un'unità di memorizzazione non rimovibile, Apple deve avere un nuovo metodo di recupero. Idee?

    It’s missing because of the new T2 chip managing drive encryption. I don’t know if there’s a new recovery method or not, but perhaps there’s a new port-to-nowhere near the T2 chip?

    Phillip Rosenthal - Replica

    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 - Replica

    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.

    Dean Lubaki -

    With the benefit of new info, I think we can safely say repoman27 nailed it.

    Jeff Suovanen -

    Ummm… Isn’t the port-to-nowhere on the other side of the board, next to the right-side cooling fan? Looks like it to me in the photos presented here.

    shamino - Replica

    @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.

    • Apple ha messo molta attenzione nel citare la sua ultima tastiera di terza generazione nel comunicato stampa. La conclamata silenziosità ci appare un concetto un po' debole, e sospettiamo che sotto ci sia dell'altro.

    • Dopo tre anni di esperienza con la rimozione delle cover dei tasti, siamo in grado di aprire il coperchio senza danneggiare le delicate clip; ed ecco una bella ricompensa.

    • Come potreste aver già sentito, qui sotto c'è una barriera in silicone nuova di zecca.

    • Come di consueto, un dissipatore di aspetto relativamente modesto si occupa di raffreddare la CPU e la grafica integrata. Come contorno c'è la sovrabbondanza di pasta termica tipica di Apple.

    • La nostra prima sbirciata alle parti in silicio ci fa scoprire il molto reclamizzato T2.

    • Già visto in precedenza nell'iMac Pro, il chip personalizzato T2 di Apple ha preso su di sé il carico di un notevole numero di funzioni. Ma noi ci aspettiamo di trovare molto altro silicio su questa scheda. Andiamolo a vedere!

    Any know why they have an NFC module in here? Some googling suggests it may contain a secure element, but surely Apple would put that in the T2 instead?

    Karl B - Replica

    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_...)

    Dean Lubaki -

    @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.

    repoman27 - Replica

    No. Continuity and the Apple Watch Mac Unlocking feature use Bluetooth.

    Dean Lubaki -

    How far can NFC work? A quick Google search says 10 cm, but Wikipedia says active NFC can be evesdropped on from as far away as 10 m - I’d assume the “legitimate” communication range would be about the same.

    • E, servito come dessert, ecco nientemeno che un nuovo caricabatterie USB-C!

    • L'alimentatore a corrente alternata incluso con questo MacBook Pro da 13" in effetti ha il nuovo numero modello A1947 (invece di A1718, dispositivo in basso), quindi è ora di attivare il cutter a ultrasuoni per saperne di più.

    • Dopo aver scavato faticosamente attraverso strati e riempitivi gommati quali non abbiamo mai visto dentro uno di questi cosi, riusciamo ad arrivare alle parti interne.

    • Rispetto a quanto richiesto da questa unità, l'apertura dell'alimentatore precedente (a sinistra) era stato una passeggiata, ma sembra che questo modello abbia beneficiato di parti interne ridisegnate, di una schermatura supplementare e di tanta schiuma gommata per una migliore resistenza agli urti.

      • Detto ciò, Apple ha anche sostituito la porta USB-C in alluminio con una in plastica...

    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.

    • Ecco che cos'è rimasto dopo che il MacBook Pro 2018 ha rivelato i suoi segreti, tra i quali ricordiamo:

    • Aggiornamento smontaggio: volevamo andare un po' più in profondità nella nuova tastiera, perciò abbiamo fatto dei test e poi ne abbiamo fatto un intero, specifico, smontaggio. Guardalo!

    • E, nel caso che ci siamo dimenticati qualcosa, dai un'occhiata agli smontaggi dei modelli 2016 e 2017: potresti trovare lì la risposta che cerchi!

    With the obscene amount of thermal paste apple puts on these things (WHY APPLE WHY?), would you recommend reapplying it—especially with an i9 on the 15” model. I’ve already seen one report about CPU throttle on the MBP 15 i9 and am wondering if I should do this as a preventative.

    steve.benfield - Replica

    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.

  4. Considerazioni Finali
    • Si può rimuovere il trackpad senza aver prima tolto la batteria.
    • Il processore, la RAM e anche la memoria flash sono saldati alla scheda logica. Riparazioni e aggiornamenti possono essere considerati (come minimo) per nulla pratici.
    • Il gruppo superiore del case, che comprende la tastiera, la batteria e gli altoparlanti, è incollato insieme. Questo rende impraticabile la sostituzione separata di tutti questi componenti.
    • Il sensore Touch ID funziona anche da pulsante di accensione ed è accoppiato con il chip T2 sulla scheda logica. La riparazione di un interruttore guasto può richiedere l'aiuto diretto di Apple oppure una nuova scheda logica.

RAID 0 SSD? From Samsung?

Peter Gamble - Replica

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?

Andrew Morrow - Replica

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

Razvan Dudas - Replica

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.

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.

Eager Wu - Replica

Is this model can stream 4K iTunes movie ready?

Ming - Replica

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 - Replica

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.

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?

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

zuxijun - Replica

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?

zjbird - Replica

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.

William Vaughan - Replica

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.

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.

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