Einleitung
Benutze diese Anleitung, wenn du dein Trackpad ausbauen willst, entweder weil es defekt ist, oder weil du an den Akku gelangen willst.
Um das Risiko eines Schadens zu verringern, solltest du dein MacBook Pro unter 25% entladen, bevor du mit dieser Reparatur anfängst. Ein geladener Lithium-Ion-Akku kann zu einem gefährlichen und unkontrollierbaren Feuer führen, falls er versehentlich perforiert wird.
Was du brauchst
-
-
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 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
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.
-
-
-
Wiederhole den vorherigen Schritt auf der anderen Seite und verwende das Plektrum, um den zweiten Clip zu lösen.
-
-
-
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.
-
-
-
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.
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.
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.
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.
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.
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.
Yeah, definitely don't pull; if you do, wear protective gloves. Mine was stuck so strongly that I just cut my palm quite deep.
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.
Using the iFixit opening Tool in the hinge opening required close to no force to open.
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.
-
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).
-
-
-
Ziehe den isolierenden Aufkleber auf der Akkuplatine an der der Akku nächstgelegenen Kante des Logic Board ab und entferne ihn.
-
Wenn sich die Abdeckung nicht leicht ablösen lässt, erwärme sie mit einem iOpener, einem Haartrockner oder einer Heißluftpistole, um den darunter befindlichen Klebstoff aufzuweichen, und versuche es erneut.
-
-
-
-
Ziehe das Klebeband vom Anschluss des Datenkabels der Akkuplatine ab.
-
Heble mit einem Spudger vorsichtig die Verriegelungsklappe am ZIF-Anschluss für das Datenkabel der Akkuplatine auf.
-
-
-
Trenne das Datenkabel der Akkuplatine, indem du es aus der Buchse auf dem Logic Board ziehst.
-
Schiebe parallel zum Logic Board in Richtung des Kabels.
-
-
-
Heble die Verriegelungsklappe am Stecker am gegenüberliegenden Ende des Datenkabels der Akkuplatine auf und trenne sie.
-
-
-
Schiebe das Datenkabel der Akkuplatine aus der Buchse auf der Akkuplatine und entferne es vollständig.

Vier 4,9 mm Schrauben
I dont have the “clicky” feedback from my trackpad anymore - please advise how to fix this
The "clicky" feedback is achieved by electromagnet on the bottom, so for anyone like me who wanted to make sure it is working before connecting battery - it will not.
(MacBook Pro 2019 15” 2 years old) There are 4 screws (2 on the left and 2 on the right, each pair held down by a black metal piece) next to the uppermost 5.8mm screws. What is the size/kind of screw are these? I’d like to purchase these missing items? Please help. A suspicious technician tried to scam me out of money. I asked for my computer back before they could charge me. I decided to do the repairs myself. When I received my laptop back and followed Ifixit instructions I found 2 screws missing and they replaced the original with an unrecognizable rusty screw on the farthest left screw hole, and the black metal pieces were missing as well.
-
-
-
Klappe das Display leicht auf, aber halte das MacBook immer noch verkehrt herum. Die Trackpad-Baugruppe sollte sich trennen und flach auf dem Display liegen.
-
Führe das Flachbandkabel des Trackpads vorsichtig durch den Schlitz im Gehäuse.
do not turn the touchpad over, as there are 4+5 very thin spacers/washers, and you might lose them. only the next step warns you about this. dont be me!
-
-
-
Achte beim Entfernen der Trackpad-Baugruppe darauf, dass du die neun kleinen Metallscheiben nicht verlierst, die auf den Schraubpfosten aufliegen. (Sie werden herausfliegen und sehr leicht verloren gehen.)
-
Entferne die Trackpad-Baugruppe.
-
-
-
Benutze einen Spudger, um die Halteklappe auf dem ZIF-Stecker des Trackpad-Flachbandkabels hochzuhebeln.
-
-
-
Erwärme mithilfe eines iOpener, eines Föns oder einer Heißluftpistole leicht den Kleber, mit dem das Ende des Flachbandkabels am Trackpad befestigt ist.
-
-
-
Schiebe die Kante eines Halberd-Spudgers oder eines Plektrums vorsichtig unter das Flachbandkabel und schiebe das Werkzeug vor und zurück, um das Kabel vom Trackpad abzulösen.
-
Schiebe das Flachbandkabel aus seinem Anschluss und entferne es vom Trackpad.

Did you manage to buy it somewhere?
Parts list with links to buy them is right at the top of the guide…
Just replaced my trackpad, really easy to do! Thanks again guys!
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.

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

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 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 - 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.

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

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.

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

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.

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.
