Introducción
Utiliza esta guía para sustituir todo el conjunto de la pantalla de tu MacBook Pro, con el fin de reparar una pantalla agrietada o defectuosa. Este conjunto también incluye los cables planos integrados para la pantalla y la retroiluminación.
Aunque hemos probado con éxito este procedimiento utilizando pantallas de sustitución originales de Apple, es posible que '''el chip T2 de Apple impida que las pantallas del mercado de accesorios funcionen correctamente, y que tu MacBook Pro no arranque como resultado de ello.
Por tu seguridad, descarga la batería de tu MacBook Pro por debajo del 25%''' antes de empezar. Una batería de iones de litio cargada puede crear un incendio peligroso e incontrolable si se perfora accidentalmente.
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 Pentalobe P5 para remover lo seis tornillos que sujetan la caja inferior:
-
Cuatro tornillos de 4.7 mm
-
Dos tornillos de 6.6 mm
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.
-
-
-
Presiona una ventosa en su lugar cerca del borde frontal de la caja inferior entre los orificios de los tornillos.
-
Levanta la ventosa lo suficiente como para abrir una pequeña grieta debajo de la caja trasera.
Throw away this suction cup and get another. It just doesn't work! Luckily I had one that does work in my tool kit.
-
-
-
Tira de la caja inferior firmemente hacia el borde frontal de la MacBook (lejos del área de la bisagra) para separar el último de los clips que sujeta la caja inferior
-
Tira primero de una esquina, luego de la otra.
-
Esto podría requerir mucha fuerza.
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.

Remueve la caja inferior.
-
Colócala en su lugar y alinea los clips deslizantes cerca de la bisagra de la pantalla. Presiona y desliza la tapa hacia la bisagra. Debe dejar de deslizarse cuando los clips se enganchan.
-
Cuando los clips deslizantes están completamente enganchados y la caja inferior se ve correctamente alineada, presiona firmemente la caja inferior para enganchar los cuatro clips ocultos. Deberías sentirlos y oírlos encajar en su lugar.
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).

-
-
Despega y remueve la etiqueta adhesiva aislante de la placa de la batería en el borde de la placa lógica más cerca de la batería.
-
Si la tapa no se despega fácilmente, aplica un poco de calor con un iOpener, secador de pelo o pistola de calor para ablandar el adhesivo e intenta nuevamente.
-
-
-
Despega la cinta que cubre el conector de cable de datos de la placa de la batería.
-
Usa un spudger para levantar suavemente la pestaña de bloqueo del conector ZIF para el cable de datos de la placa de la batería.
-
-
-
-
Desliza el cable de datos de la placa de la batería de su zócalo en la placa de la batería y remuévelo completamente.
Bonjour, super Tuto, petite question elle sert a quoi cette nappe , et quesqui se passe si elle est pas branché ?

-
-
Usa un spudger para levantar suavemente el conector de alimentación de la batería, desconectando la batería.
Put a little bit of insulating tape over the terminal to be safe.

Usa un destornillador T3 Torx para remover los dos tornillos de 3.5 mm que sujetan la cubierta del cable flexible de la pantalla.
-
Remueve la cubierta del cable flexible de la pantalla.
T3 or T4? I almost damage the screw trying with the T3.
I’d say T4 as T3 was definitely too small

-
-
Utiliza un destornillador Torx T3 para quitar los dos tornillos de 1.7 mm que sujetan el soporte para el conector del cable de la placa de la pantalla.
-
Remueve el soporte del conector de cable de la placa de la pantalla.

-
-
Utiliza un destornillador Torx T5 para quitar los cuatro tornillos de 3.3 mm que sujetan la placa de la pantalla
-
Asegúrate de que el cable flexible de la placa de pantalla se ubique sobre la placa, no por debajo.
When reassembling, I found that I had to press in on the outer edge of the antenna (top edge when looking at the picture) at the midpoint between the left 8 screws and the right 8 screws as I screwed the display board screws in. I found that the outside antenna edge would otherwise rub against the display halfway through opening it making a pop sound. Installing this way fixed the problem.

Usa un destornillador Pentalobe P2 para remover 16 tornillos de 1.5 mm que sujetan el ensamblaje de la antena.
I’m having difficulty removing the screws. I’m not sure if the p2 screwdriver is defective but I am now stuck at this step.
We had 4 MBP's that I removed the displays from. On this step, I stripped a 'middle' screw on each side.
On the second one, I also noticed the middle screws didn't exactly want to easily come loose as I worked my way down the row.
I wound up putting all screws back in, loosened then tightened the screw on the opposite end, then removed the two in the middle (without issue), then an outside screw going back and forth, until I just had one on each end. Since I had already removed and replaced them, they came out without issue.
I used this method on the remaining 2 MBP's and had no further issues.
YMMV and it may not even be necessary. Just seemed removing the screws from end to end put enough pressure on the remaining ones that they were harder to remove. Whereas a patterned removal seemed to resolve that 'issue'.

Utiliza un destornillador Torx T8 para quitar los dos tornillos de 4.9 mm restantes de la bisagra d (uno de cada bisagra).
-
Quita el último tornillo por última vez, usando una mano para sujetar ambas mitades del MacBook Pro para asegurarse de que no se separen y caigan inesperadamente.

This is such a noob question but how do I marked that”I did this repair”.
I followed all of these steps to replace my display and when I put it all back together my Mac would only turn on when it was plugged into the wall. So the new display works fine but it doesn’t seem to recognize the battery at all. Has anyone run into this problem and know what the issue might be?
Jason - did you plug the battery connector and cable back in correctly?
I need anew battery connector mine i missing one end maybe …
my screen was replaced by a dealer and I found missing screws and the battery board data cable was glued so hard with a piece of tape when I pulled it out one side showed connection wires the other was nothing ,what don I do when I get a new one (if i can get one?..,,,
i am confused by the direction and how difficult such a simple step can stop me cold the battery connector is very fragile and i was not prepared for the outcome
i need help what can i do next. Thanks

Can this model MacBook Pro 2019 A1990 work as a headless Mac
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.
Kyle B - Contestar
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.
Brian - Contestar
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=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 - 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.
hatuxka - Contestar
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.
Mircea Comanici - Contestar
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.
