Einleitung
Folge dieser Anleitung, um dein Trackpad auszubauen, um es zu ersetzen, oder um an den Akku heranzukommen.
Entlade den Akku deines MacBook Pro aus Sicherheitsgründen auf unter 25%, bevor du anfängst. Ein geladenen Lithium-Ionen-Akku kann ein gefährliches und unkontrollierbares Feuer auslösen, falls er versehentlich perforiert wird.
-
-
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.
-
sudo nvram AutoBoot=%03
-
-
-
Entferne sechs P5 Pentalobeschrauben, mit denen die Gehäuseunterseite befestigt ist. Sie haben folgende Längen:
-
Vier 3,7 mm Schrauben
-
Zwei 7,3 mm Schrauben
-
-
-
Drücke einen Saugheber nahe an der Vorderkante des unteren Gehäuses zwischen den Schraubenlöchern fest.
-
Ziehe den Saugheber soweit hoch, dass ein kleiner Spalt unter der Gehäuseunterseite entsteht.
-
-
-
Schiebe die Ecke eines Plektrums in den eben entstandenen Spalt an der Gehäuseunterseite ein.
-
Schiebe das Plektrum um die nächste Ecke herum und dann bis zur Seitenmitte des MacBooks hoch.
-
-
-
Wiederhole den vorherigen Schritt auf der anderen Seite. Nutze ein Plektrum, um die zweite Raste zu lösen.
-
-
-
Hebe die Vorderkante der Gehäuseunterseite (also die Kante gegenüber den Scharnieren) soweit an, dass du mit den Fingerspitzen hineingreifen und sie gut fassen kannst.
-
-
-
Ziehe die Gehäuseunterseite kräftig zur Vorderkante des MacBooks hin (also weg von den Scharnieren), so dass sich auch die letzte verbliebene Raste öffnet.
-
Ziehe zuerst an einer, dann an der anderen Ecke.
-
-
-
Entferne die Gehäuseunterseite.
-
Lege es passend hin und richte die Rasten zum Einschieben nahe an den Displayscharnieren aus. Drücke nach unten und schiebe den Deckel in Richtung der Scharniere. Er sollte nach dem Einrasten anhalten.
-
Wenn die Rasten fest sitzen und die Gehäuseunterseite gut ausgerichtet ist, dann drücke die Gehäuseunterseite fest nach unten, bis die vier verborgenen Rasten einschnappen. Du solltest diesen Vorgang hören und fühlen können.
-
-
-
Zur Isolation ist ein Aufkleber über der Akkuplatine an der Kante des Logic Boards direkt beim Akku angebracht. Ziehe ihn ab.
-
Wenn sich der Aufkleber nicht leicht lösen lässt, dann erwärme ihn leicht mit einem iOpener, einem Haartrockner oder einem Heißluftgebläse. Wenn der Kleber weich ist, versuche es erneut.
-
-
-
Klappe behutsam den Sicherungsbügel am ZIF-Verbinder des Datenkabels zur Akkuplatine hoch.
-
-
-
Schiebe das Datenkabel zur Akkuplatine aus dem Anschluss auf dem Logic Board heraus und trenne es ab.
-
-
-
Löse das Klebeband über dem Stecker des Akkuplatinen-Datenkabels ab.
-
Heble die Sicherungsklappe des Steckers am anderen Ende des Akkuplatinen-Datenkabels hoch und trenne ihn ab.
-
-
-
Schiebe das Akkuplatinen-Datenkabel aus seinem Anschluss auf der Akkuplatine heraus und trenne es ab.
-
-
-
Entferne die beiden 1,8 mm Torx T3 Schrauben, mit denen die Abdeckung der Stecker vom Trackpad- und Tastaturkabel befestigt ist.
-
Entferne die Abdeckung.
-
-
-
Heble den Trackpadkabelstecker mit dem Spudger senkrecht hoch und trenne ihn vom Logic Board ab.
-
-
-
Erwärme das Flachbandkabel zum Trackpad ein wenig, so dass die Klebeverbindung zum Akku aufgeweicht wird.
-
-
-
Entferne die dreizehn Torx T5 Schrauben, mit denen die Trackpad-Einheit befestigt ist:
-
Neun 5,8 mm Schrauben
-
Vier 4,9 mm Schrauben
-
-
-
Klappe das Display ein wenig auf, aber lasse das MacBook immer noch umgekehrt liegen. Die Trackpad-Einheit sollte sich lösen und flach auf dem Display aufliegen.
-
Ziehe das Flachbandkabel des Trackpads vorsichtig durch seinen Schlitz im Rahmen.
-
-
-
Achte beim Entfernen der Trackpad-Einheit darauf, nicht die neun kleinen Metall-Unterlegscheiben auf den Schraubpfosten zu verlieren. (Sie können leicht abfallen und verloren gehen.)
-
Entferne die Trackpad-Einheit.
-
Vergleiche dein Ersatzteil mit dem Originalteil, eventuell musst du Komponenten übertragen oder Schutzfolien vom Neuteil abziehen, bevor du es einbauen kannst.
Um dein Gerät wieder zusammenzubauen, folge diesen Schritten in umgekehrter Reihenfolge.
Entsorge deinen Elektromüll fachgerecht.

I have a macbook pro 16" from 2019, it did not give me a haptic response, the Force Touch is sensitive to touch and pressure but there was no sensation of "click" or vibration, I disassembled the mac and the trackpad out of pure curiosity, and when closing and turn on the mac, the trackpad was completely unusable as well as the keyboard and the fans at full, I already tried to restore PRAM and SMC with an external keyboard and nothing worked, I already started in safe mode and neither. I reopen it to verify all the grants but there is nothing visibly wrong. Please Help...
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 -
@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.

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 -
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(

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 -
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 -
Not able to do that with damaged screen
richardjgreen -
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

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 -
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 -
running `nvram -p | grep 'AutoBoot'` in terminal verifies that it was accepted
result: `AutoBoot %00`
Marek Polák -
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 istrue- and then to change it,sudo nvram auto-boot=falsewhich 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 -
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 -
I didn’t do this. Mine never auto-booted before I replaced the battery. Now it does.

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 -
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 -
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 -
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 -
This should be the default. IMO I tell you to power on - not the lid.
G Sena -
Est ce que cela fonctionne sur un macbook pro 2017 sans touchbar ?
maël muzelet -
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 -
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.
