Introducción
Usa esta guía para reemplazar el ensamblaje de pantalla de tu MacBook Pro 13" Touch Bar 2019.
Para tu seguridad, drena la batería del MacBook Pro debajo de 25% antes de que las reparaciones comiencen.
Qué necesitas
-
-
Enciende tu Mac y ejecuta Terminal.
-
Copia y pega el siguiente comando (o escríbelo exactamente) en la Terminal:
-
sudo nvram AutoBoot=%00
-
Presiona [return]. Si se te solicita, introduce tu contraseña de administrador y vuelve a pulsar [return]. Nota: La tecla de retorno también puede estar etiquetada como ⏎ o "enter".
-
sudo nvram AutoBoot=%03
-
-
-
Usa un destornillador P5 Pentalobe para remover los seis tornillos que sujetan la caja inferior.
-
Dos tornillos de 6.2 mm
-
Dos tornillos de 5.3 mm
-
Dos tornillos de 3.4 mm
-
-
-
Inserta tu púa de apertura una vez más bajo el borde frontal de la caja inferior, cerca de uno de los dos agujeros centrales para tornillos.
-
Dale un giro firme a la púa para liberar el tercer clip que asegura la caja inferior al chasis.
-
Repite este procedimiento cerca del otro de los dos orificios centrales para tornillos, liberando el cuarto clip.
-
-
-
Tira de la caja inferior con firmeza hacia la parte delantera de la MacBook (lejos de la zona de la bisagra) para separar el último de los clips que aseguran la caja inferior.
Tip: If you use a spudger as a lever, placing the thin end inside the hinge and pressing lightly towards the bottom casing, it pops out quite easily.
-
-
-
Remueve la caja inferior.
-
Ponla en su lugary alinea los clips deslizantes cerca de la bisagra de la pantalla. Presiona hacia abajo y desliza la cubierta hacia la bisagra. Debería dejar de deslizarse cuando los clips se enganchen.
-
Cuando los clips deslizantes estén totalmente encajados y la caja inferior parezca estar correctamente alineada, presiona firmemente sobre la caja inferior para que encajen los cuatro clips ocultos que hay debajo. Deberías sentir y oír cómo se encajan en su lugar.
Hab zum Schluss das Blaue OpeningTool benutzt und am Rahmen in der nut eingehackt um den Deckel final hinein zu drücken. Da er per Hand nur bis zu einem gewissen Punkt geht
-
-
-
Con cuidado, despega el gran trozo de cinta que cubre el conector de la batería, en el borde de la placa lógica más cercana a la batería.
-
Remueve la cinta.

Utiliza un destornillador Torx T5 para quitar el tornillo de torta de 3.7 mm que sujeta el conector de alimentación de la batería.
io ho trovato un Torx T4 invece del T5.
Ciao Stefano! Grazie per il commento. Infatti c’è sempre una certa tolleranza fra il cacciavite e la testa delle viti. Quindi è possibile che un cacciavite più grande o più piccolo sia più “comodo” in certi casi. Buona riparazione!
konnte diese Verbindung nicht lösen. Zu sehr angezogen

-
Utiliza un spudger para levantar suavemente el conector de alimentación de la batería, desconectando la batería.
-
Levanta el conector lo suficiente para que se mantenga separado de su zócalo. Si accidentalmente hace contacto durante el transcurso de la reparación, podría dañar tu MacBook Pro.
Please save yourself a pile of money and read this before doing this step: I bricked my MacBook by not being extremely careful and making sure to NOT touch the connector together as I took it apart. Ouch ouch ouch. 😫

-
Quita los cuatro tornillos T3 Torx de 3.3 mm que aseguran las cubiertas de plástico en la parte superior de las bisagras de la pantalla.
-
-
-
Retira los dos tornillos Torx T3 de 1.7 mm que aseguran la cubierta de aluminio en la parte superior del conector del cable flexible de la pantalla.
-
Remueve la cubierta.
I have done 2 these these exact same 2019 MacBooks now, and both times The screw on the right seems to not be a T3. At first it appeared that I stripped it, but once I got to the second one and I was very gentle with it, it’s a totally different screw. And I can’t figure out what it is… But the T3 or the T4 will not remove it. Neither will a Pentolope. I just removed the left screw, and then I pivoted the cover away so I could remove the connecter. Anyone else having this issue?
You’re right, noahmadsen, they’re super slightly, but different.
-
-
-
Retira los cuatro tornillos Torx T3 de 1.5 mm que aseguran las dos cubiertas de aluminio en la parte superior de los dos conectores del cable de la pantalla.
-
Usa un par de pinzas para quitar las dos cubiertas de aluminio.
FYI.....during reassembly, the new screen may come with these already attached so compare the old screen to the new one before installing.
-
-
-
Usa una púa de apertura para sacar el ensamblaje del cable de la antena en las áreas que se muestran.
I stripped these, is there any tips on getting these out?
Mark, here's a guide with tips for removing stripped screws. Hope it helps—best of luck!

Remueve el ensamblaje del cable de pantalla.
After doing the job the first time, when I opened the display there was something clicking loudly. I had found out that this antenna assembly wasn’t put back properly. When reinstalling this, there is a flat metal piece on the bottom centre of the antenna assembly. Mine became bent for some reason. I had to bend it back straight. It needs to click back in to top case. Problem solved!
Same happened to me, there’s a small canal in the top case where the antena must be vertically inserted, if you just push it horizontally in place it will fit and you will be able to reassemble the computer, but the antenna will be sligthly bent and cause friction with the screen when opening.

-
Retira los cuatro tornillos Torx T3 de 3.9 mm que aseguran las bisagras de los dos cables de la pantalla.
T4 worked best for me
-
-
-
Agarra el lado izquierdo del cable de la pantalla y tira de él hacia el extremo inferior del MacBook y lejos de la bisagra de muelle.
-
Usa un par de pinzas para sacar la bisagra de muelle del cable de la pantalla de su soporte.
-
Repite este paso con la bisagra derecha del cable de la pantalla.
-
-
-
Empuja ambas mitades del MacBook Pro juntas para que los soportes de las bisagras se puedan levantar y queden libres de sus huecos en el chasis.
-
Empuja el cuerpo principal de la MacBook Pro hacia ti mientras tiras de la pantalla hacia usted para separarla.
-
Retira el ensamblaje de la pantalla, teniendo cuidado de no engancharlo en ningún cable.
When reassembling, make sure to align the back edge of the new display assembly (hinge side) with the edge of the MacBook body, then tighten the hinge screws. Misalignment can cause the MacBook to open and close improperly. It should feel smooth where the gaps are between the two halves.

Why does the guide suggest purchasing the "MacBook Pro 13" Retina (A1708, A2159) Display Cable "
Replaced my display with a genuine used panel and the true tone still worked. However, be very careful of the touchbar flex.
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 - Contestar
@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 - Contestar
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 - Contestar
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 - Contestar
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 - Contestar
Not able to do that with damaged screen
richardjgreen - Contestar
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 - Contestar
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 - Contestar
running `nvram -p | grep 'AutoBoot'` in terminal verifies that it was accepted
result: `AutoBoot %00`
Marek Polák - Contestar
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 - Contestar
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 - Contestar
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 - Contestar
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 - Contestar
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.

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