MacBook Pro (15 Zoll, 2019, Touch Bar) Gehäuseunterteil tauschen

Was du brauchst

  1. MacBook Pro (15 Zoll, 2019, Touch Bar) Gehäuseunterteil tauschen, Auto Boot deaktivieren: Schritt 1, Bild 1 von 3 MacBook Pro (15 Zoll, 2019, Touch Bar) Gehäuseunterteil tauschen, Auto Boot deaktivieren: Schritt 1, Bild 2 von 3 MacBook Pro (15 Zoll, 2019, Touch Bar) Gehäuseunterteil tauschen, Auto Boot deaktivieren: Schritt 1, Bild 3 von 3
    • Zuallererst musst du die automatische Startfunktion (Auto Boot) deines Macs deaktivieren. Auto Boot schaltet deinen Mac ein, wenn du ihn aufklappst, was versehentlich beim Auseinanderbau passieren kann. Benutze diese Anleitung oder befolge die anschließende Kurzversion zum Deaktivieren von Auto Boot. Dieser Befehl funktioniert eventuell nicht auf allen Macs.

    • Schalte deinen Mac ein und starte Terminal.

    • Kopiere den folgenden Befehl und füge ihn im Terminal ein (oder tippe ihn exakt so ein):

    • sudo nvram AutoBoot=%00

    • Drücke die Eingabetaste [return]. Wenn du dazu aufgefordert wirst, gib dein Administratorpasswort ein und drücke erneut [return]. Hinweis: die Return-Taste kann auch mit ⏎ oder "enter" gekennzeichnet sein.

    • Nun kannst du deinen Mac sicher herunterfahren und das untere Gehäuse öffnen, ohne dass er sich versehentlich einschaltet.

    • Nachdem deine Reparatur zu Ende ist und dein Gerät wieder erfolgreich zusammengebaut ist, musst du Auto Boot mit folgendem Befehl wieder aktivieren:

    • sudo nvram AutoBoot=%03

    Is this step necessary? I can’t perform this step as I am attempting to repair water damage and need to remove logic board & most likely replace the battery.

    Macrepair SF - Antwort

    @mac_medic You definitely don’t want the power coming on while the board is wet. In your case, I think powering on the machine to disable Auto Boot would do more damage than it prevents. I agree, skip this step and be prepared to disconnect the battery quickly if the laptop automatically powers on. Good luck!

    Jeff Suovanen -

    Thats right! You don't want power running while working on your logic board.

    Dan -

    This did not work when running High Sierra.

    Kyle B - Antwort

    Tried this on a 2018 MBP 13” Touchbar (there’s no iFixit guide for this model yet). Need to replace a broken screen.

    Luckily I managed to connect to an external screen (Cmd-Down Brightness to switch displays) and enter above command. Seems to work, but there’s another problem with this model - it powers up as soon as any key is pressed……. ffs <gnashes teeth>

    Cool_Breeze - Antwort

    I unscrew the battery first and wrap electrical tape over the logic board battery connector before attempting any repairs to the board. Haven’t had any problems yet and I’ve worked on about 10 of these models already. Also when you open the bottom case use a suction cup at the bottom and pull up then run a plastic spudger along the edges to disconnect the clips. Also only use a plastic spudger on the board. Saw a youtube video from a repair shop and he did not disconnect the power and used all metal tools during the entire process of removing the board. His last step was to disconnect the battery terminal.

    Is this step necessary if my mac can turn on? Battery fully dead(

    Nursat b - Antwort

    BEFORE YOU START: The included torx head stripped off before I was done (and you might need an additional T4) so stop now and go buy a good one. Also they fail to warn you above to get some blue threadlocker ahead of time.

    Jason Sherron - Antwort

    This command did not work for me and I read that sometime in later 2020 Apple stopped this command from working…any ideas on a work around?

    Patrick Machacek - Antwort

    Not able to do that with damaged screen

    richardjgreen - Antwort

    If you have a damaged screen you can still use a converter from thunderbolt (USB 3) to HDMI and plug your Macbook Pro to your TV as monitor display. Just make sure to chose the right Source (HDMI IN) in your TV. I did it and to make it work I unplug and plug again in my Macbook and so I could disable the Auto boot

    Roberto Sanchez Bustos -

    Hi. This does not work on 2018 13” MacBook Pro with Touch Bar. I did exactly this to disable auto boot. But when I check by using nvram -p it says: auto-boot true. Am I doing something incorrectly? I did everything step by step. Copied and pasted the sudo command, pressed enter and then entered my password. I have Big Sur 11.1 installed. Is there any other way since I need to replace the screen. Thank you. Adrian

    Adrian Vizik - Antwort

    Hi everyone. This is also a little pointless if you can’t see anything on the screen, and you don’t have a display adapter to USB C to display it. I agree with Brian about removing the back and disconnecting the battery cable before you even think about opening the lid of the MacBook. Applying the insulation tape is also a handy little tip that just makes sure there is no way to discharge from either the board or battery.

    Roberto Enrieu - Antwort

    running `nvram -p | grep 'AutoBoot'` in terminal verifies that it was accepted

    result: `AutoBoot %00`

    Marek Polák - Antwort

    Running Big Sur 11.6.7 on a 2019 16" MBP, it's "auto-boot". So it's: nvram -p | grep 'auto-boot' to display the current state, the default is true - and then to change it, sudo nvram auto-boot=false which turns it off.

    Ed Mechem -

    This step is completely unnecessary if you follow the guide to disconnect the battery properly. Just put some tape between the battery and logic board connection to prevent it from accidentally touching and therefore powering on the laptop.

    Grant Ormsby - Antwort

    It took me a few tries to make this command work, as I was able to copy and paste the command into Terminal, but could not type in my laptop’s password. I finally typed my password into a text document, copied it (command C), and then pasted it into Terminal and it worked.

    tommy404 - Antwort

    I didn’t do this. Mine never auto-booted before I replaced the battery. Now it does.

    hatuxka - Antwort

    BEFORE YOU DO ANYTHING - CHECK THE BATTERY!

    I-fixit sent me a bad battery, which I didn’t realize until it was already install. They sent me a new one, but I wasted hours uninstalling and reinstalled.

    Get a volt meter and measure the voltage on the output of the battery pack. If it reads 0 V, SEND IT BACK. It should read over 2 V.

    bcardanha - Antwort

    I've just received my replacement battery and it reads 0,042V between the two main connectors. Do you think it's dead?

    peter sussex -

    When I did this from Terminal.app within Recovery Mode, the “sudo” was not recognized but I could invoke it without the sudo part. It seems to have been accepted when looking at “nvram -p”

    johann beda - Antwort

    When in Recovery Mode, you already have superuser powers. So you don't need to prefix commands with the sudo command to invoke them with root privileges; you already have them. Do a pwd (print working directory) after opening Terminal in Recovery Mode, and you'll see that you're in the root user's directory.

    Ed Mechem -

    I received the battery kit for my 2018 MacBook Pro and as per the above comment from bcardanha - Oct 12, 2021, I checked the voltage on the pads marked + and - . It was zero volts so I panicked a bit.

    I sent a message on the iFixiT Facebook page and I got no reply. I finally found the customer service email for Ifixit Europe and sent them an email voicing my concern as I was not keen to work for couple of hours just to discover that the battery is faulty. I had an almost instant reply on the email (kudos to them) and they adviced me to go ahead and install the new battery as the voltage measured when battery is not connected is not relevant.

    I took a leap of faith and after two hours… the new battery showed 50% charge and everything seems to be working just fine. I am happy it worked.

    Mircea Comanici - Antwort

    After removing the old battery and installing the new battery I powered up the MBP before screwing the bottom on. I discovered the my keyboard would not function. It took a few hours of investigation and frustration that I discovered the track pad power ribbon had become partially dislodged from the trackpad. I was able to see that this through the little machined slot where the battery sat. I had to remove the trackpad to reinsert the power ribbon back into the connector in the trackpad. after reassembling and reinstalling the battery etc the keyboard worked. Just food for thought if your run into the keyboard issue.

    Ed Mease - Antwort

    This should be the default. IMO I tell you to power on - not the lid.

    Est ce que cela fonctionne sur un macbook pro 2017 sans touchbar ?

    maël muzelet - Antwort

    Bonjour Maël, oui, ce tutoriel concerne "les MacBook Pro 2016 (et plus récents) et les MacBook Retina 12" 2017 (et plus récents)"

    Claire Miesch -

    Excellent instructions. I was able to follow and install the new screen. I recommend that you get a good set of tools before you begin. I started with an inexpensive repair kit bought online. The Penta and torx bits failed. I bought an IFIXIT kit with quality bits and I was able to do everything I needed.

    Tom Markham - Antwort

    If you're not running an admin account the sudo command won't work (which honestly, you should not be running admin). Rather than logging in to your admin amount via the OS, in the terminal type "login [admin username]," then the password and you'll be able to do the sudo command as described above. Once you're complete, type "logout [admin username]" and you'll be good to go. Obviously replace [admin username] with whatever the account name for your admin user is.

    arichard2401 - Antwort

    For those unable to complete this step because the screen is too damaged I recommend leaving your macbook on until the battery dies.

    Nicholas R Licato - Antwort

    Just replaced my 2018 15" MBP battery. Running Sonoma.
    I found no way to disable AutoBoot (The status can be checked in the Power section of system report).

    Anyway, i left my battery completely drain before opening the MBP, and had no issues during the process.

    Cédric Bontems - Antwort

    After sending this command in terminal when I checked what happens if I now open the lid, instead the screen lit slightly up (still black) then a battery symbol showing the charging state showed up.

    Now, after replacement of the battery, this is all I get to see.

    No reset of NVRAM nor PRAM helped.

    Currently the new battery charges (58% atm) and it feels like it‘s mocking me.

    webrockers - Antwort

    I suspected the keyboard or TouchID sensor wouldn’t work, so I went on and checked every connector.

    I missed connecting the left TouchID sensor from step 31.

    • Schalte dein MacBook Pro vollständig aus und ziehe den Stecker aus der Steckdose, bevor du anfängst. Schließe das Display und drehe den Laptop um.

    • Entferne mit einem P5-Pentalobe-Schraubenzieher die sechs Schrauben, mit denen das untere Gehäuse befestigt ist:

    • Vier 4,7 mm Schrauben

    • Zwei 6,6 mm Schrauben

    • Du wirst sehen, dass die Schrauben in einem leichten Winkel herauskommen. Du musst sie dann später auch genau so wieder einsetzen.

    • Merke dir gut, wo welche Schraube war und vergewissere dich, dass du sie wieder genau dort eindrehst, wo du sie herausgedreht hast, um Schäden an deinem Gerät zu vermeiden.

    I miss a printable template to leave the screws and removed parts on it for future identification when reassembly, linked maybe with the location in the Macbook, or with the number of the step.

    • Drücke den Saugnapf in der Nähe der Vorderkante auf das untere Gehäuse zwischen den Schraubenlöchern.

    • Ziehe den Saugnapf gerade so weit nach oben, bis eine kleine Lücke unter dem unteren Gehäuse entsteht.

    Throw away this suction cup and get another. It just doesn't work! Luckily I had one that does work in my tool kit.

    • Schiebe die eine Ecke eines Plektrums in die entstandene Lücke.

    • Schiebe das Plektrum um die nächste Ecke und dann zur Hälfte über die Seite des MacBook Pro.

    • Dadurch wird der erste der verdeckten Clips freigegeben, mit denen das Gehäuse gesichert ist. Du solltest den Clip erfühlen und ihn klicken hören.

    • Hebe die Vorderkante des unteren Gehäuses (die dem Displayscharnier gegenüberliegende Seite) so weit an, dass du mit den Fingerspitzen darunter gleiten und es gut greifen kannst.

    • Zwei zusätzliche verdeckte Clips in der Mitte der Abdeckung können an dieser Stelle klicken und sich öffnen, sofern dies noch nicht geschehen ist.

    • Hebe nicht zu weit an und versuche noch nicht, das Gehäuse vollständig zu entfernen.

    • Ziehe das untere Gehäuse fest in Richtung der Vorderkante des MacBook (vom Scharnierbereich weg), um die letzten Clips zu lösen, mit denen das untere Gehäuse gesichert ist.

    • Ziehe zuerst an einer Ecke und dann an der anderen.

    • Zur Seite ziehen - nicht nach oben.

    • Das könnte ziemlich viel Kraftaufwand bedeuten.

    With the amount of force needed to carefully pull the back panel out, this caused the back panel to scratch the battery. I don't see or hear any expansion, but this still has me concerned.

    gladgura - Antwort

    this step must require a lot of force. I tried to pull it with the plastic hookie thing from the ifixit set by hooking it in one of the screw holes — the tip of the hookie thing broke.

    Oleksii Toldaiev - Antwort

    The amount of force required for removing the bottom cover is absolutely ridiculous. Almost feels like i'm about to push my MacBook towards the wall the second it comes off.

    Be careful, I ended up breaking 2 grounding pins on the motherboard last time I tried opening my computer up.

    techtalkf - Antwort

    PLEASE DON'T PULL!!!

    Instead just gently push with plastic pick from the other side (where vents outputs are) towards the center... Cover will very easily open that way.

    I hope iFixit will correct this step.

    Kamil Roman - Antwort

    Came here to share exactly this.

    Robert -

    That's definitely how this step should be done. Thanks!

    VovS -

    If someone has a photo to share regarding this comment, it might be very useful. Thanks.

    Mark Cohen -

    I used a screwdriver at 45 degrees angle and pushed the cover from the hinges, it worked really smooth. I had it close to the corners.

    Martin Lundgren - Antwort

    Yeah, definitely don't pull; if you do, wear protective gloves. Mine was stuck so strongly that I just cut my palm quite deep.

    Kirill Chernov (PowerDoge) - Antwort

    You would think ifixit would investigate why the last step required them to pull with great force to remove the bottom case lid as the solution.

    It's counter-intuitive to use an excessive method to remove a part.

    There's always an easier way. It's frustrating because you can't see inside.

    Cary B - Antwort

    Using the iFixit opening Tool in the hinge opening required close to no force to open.

    Anders Markstrom - Antwort

    Ah... after attempting to 'pull' this rear cover off, to no avail, I tried to coax the cover off with a nylon pry tool. MUCH better! iFixIt will do well to amend it's recommendation to 'pull' this cover in any way. All I wanted to do was a little house cleaning and exorcize the dust bunnies that took up residence in my MBP's fans. Today is much quieter. Thank you all for pointing out the obvious.

    • Entferne das untere Gehäuse.

    • So baust du das untere Gehäuse später wieder ein:

    • Lege es in Position und richtedie Clips in der Nähe des Displayscharniers aus. Drücke die Abdeckung nach unten und schiebe sie zum Scharnier. Es sollte nicht mehr rutschen, wenn die Clips einrasten.

    • Wenn die Clips vollständig eingerastet sind und das untere Gehäuse korrekt ausgerichtet ist, drücke fest auf das untere Gehäuse, um die vier verdeckten Clips darunter einzurasten. Du solltest fühlen und hören, wie sie einrasten.

    If I had it all to do over, again, I would blow out the dust with compressed air at this point. During the disassembly, I kept encountering little dust bunnies, and I was very worried that one would get caught in one of the connectors when I plugged everything back up (which wouldn’t get discovered until I put it all back together and tried out all of the components).

What about a guide for replacing the SSD for more memory? Is this possible?

Sara Morsi - Antwort

@eowyn327 Not possible on any of Apple’s current laptops. They want you to buy a new machine or pay them a monthly fee for iCloud storage, rather than have the ability to expand the internal storage. Only other option is to tote around an external SSD and a dongle. Sorry!

Jeff Suovanen -

When I opened the bottom case and shook it a little, it rattles a little as if something was loose. Is this normal? I didn’t actually open the case, just popped the clips and closed it back up.

Sarah - Antwort

I need to re-tap the threads on two of the lower case screw holes. Can anyone tell me what the diameter and pitch is?
