Introducción
Utiliza esta guía para sustituir todo el ensamblaje de pantallas de tu MacBook Pro, con el fin de arreglar una pantalla agrietada o defectuosa.
Para tu seguridad, descarga la batería de tu MacBook Pro con una carga inferior al 25% antes de empezar.
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 seis tornillos que sujetan la caja inferior.
-
Dos tornillos de 6.2 mm
-
Cuatro tornillos de 3.4 mm
-
-
-
Aplica una ventosa a la parte inferior de la caja, cerca de la zona central del MacBook Pro.
-
Levanta la ventosa para crear una grieta entre la caja inferior y el chasis.
-
-
-
Inserta una esquina de una púa de apertura en el espacio entre la caja inferior y el chasis.
-
Desliza la púa de apertura alrededor de la esquina más cercana y a la mitad del lado de la caja.
-
-
-
Repite el paso anterior en el lado opuesto, deslizando la púa de apertura debajo de la minúscula y subiendo por el lado para liberar el segundo clip.
Recommend being very careful on this step and the following step when using any opening tool to always keep the “pointy end” up when prying, especially about 40mm up the side, to avoid completely destroying the speaker diaphragms.
-
-
-
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 el paso anterior en el lado opuesto, deslizando la púa de apertura debajo de la minúscula y subiendo por el lado para liberar el segundo clip.
-
-
-
Tira de la caja inferior con firmeza hacia la parte delantera del MacBook (lejos de la zona de la bisagra) para separar el último de los clips que aseguran la caja inferior
-
Tira primero en una esquina, luego en la otra.
-
-
-
Remueve la caja inferior.
-
Colócalo en su lugar y 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 están totalmente acoplados y la caja inferior parezca estar correctamente alineada, presiona firmemente sobre la caja inferior para acoplar los cuatro clips ocultos que hay debajo. Deberías sentir y oírlos encajar en su lugar.
-
-
-
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.
-
-
-
Usa la punta de un spudger para levantar la pequeña lengüeta negra de cierre que asegura el cable en su conector.
Be very careful here. It is easy to break the whole connector off the battery board, which is what I did. Luckily the connector is part of the replacement battery, so you just need to remove the connector from the cable. The pictures here should provide more detail so you can see better what is going on.
thanks a lot !!!!! great help :)
-
-
-
Desconecta el cable de datos de la placa de la batería deslizándolo de su zócalo.
-
Deslízate en paralelo a la placa lógica, en la dirección del cable.
As simple as this step might seem, the golden leads will disapper the moment you remove it as it has some adhesive under the black strip that covers it. Ensure you peel it back enough to display the golden leads after swapping the batteries out.
Your battery may come with this ribbon cable. In that case, disconnect the other end.
-
-
-
-
Dobla el cable de datos de la placa de la batería a un lado y apártalo.
-
-
-
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 enchufe. Si accidentalmente haces contacto durante el transcurso de la reparación, podrías dañar tu MacBook Pro.
To completely avoid accidental contacts I recommend to wrap this connector in a piece of paper and hold it in place with tape.
Do not put tape directly on the contact underside, as that may leave some glue that would affect the contact conductivity.
I put a piece of tape on the underside of the connector (sticky side up) to insure against accidental battery contact. If you put tape on the logic board side of the connection, some insulating padding material might accidentally stick to the tape when the tape is removed during reassembly.
-
-
-
Remueve los cuatro tornillos T3 Torx de 1.9 mm que sujetan las tapas de plástico encima de las bisagras de la pantalla.
-
Remueve ambas tapas de plástico de las bisagras.
-
-
-
Retira los dos tornillos Torx T3 de 2.9 mm que aseguran la cubierta de aluminio en la parte superior del cable principal de la pantalla.
-
Remueve la tapa.
I had to use a T4 instead of a T3 to remove these ones
-
-
-
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 tapa.
t4 works better for these screws
T4 screw is correct
stripped the freaking screw - now I'm screwed
-
-
-
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 tapas de aluminum.
-
-
-
Desconecta cuidadosamente los tres cables coaxiales de la antena, sacándolos directamente de la placa lógica.
-
-
-
Usa una púa de apertura para sacar el ensamblaje del cable de la antena en las áreas que se muestran.
-
-
-
Retira cuidadosamente el ensamblaje de la antena mientras que simultáneamente alimentas el paquete de cables de antena por debajo del tubo termosifón bifásico.
When refitting the antenna assembly be aware there’s a locating lug in the centre of the cavity that it needs to fit over. I slid it back in without noticing this on my first attempt and it leaves the screw holes about 1mm out of alignment and causes the assembly to slightly catch you when open/close the lid.
Yes, totally thanks David, I had to disassemble and reassemble the Macbook because of this small metal "sheet". The screen was doing a small noise when I was opening it (a "poc")
-
-
-
Remueve el ensamblaje del cable de la antena
-
-
-
Quita los cuatro tornillos Torx T3 de 3.9 mm que sujetan los dos resortes de la cubierta del cable de la pantalla.
T4 works better there !
I guess it depends on your tools. Maybe a worn T4 would fit, mine wouldn't. T3 it is.
-
-
-
Agarra el lado izquierdo del ensamblaje del cable de la pantalla y tira de él hacia el extremo inferior de la MacBook y alejándolo del resorte de la cubierta.
-
Usa un par de pinzas para sacar el resorte de la cubierta del cable de la pantalla de su hueco.
-
Repite este paso con el resorte de la cubierta derecha del ensamblaje del cable de la pantalla.
-
-
-
Coloca suavemente tu computadora portátil con el teclado hacia abajo sobre el borde de una mesa para que la pantalla cuelgue hacia abajo.
-
-
-
Afloja, pero no retires, los seis tornillos Torx T8 que sujetan las bisagras.
-
-
-
Mantén el cuerpo principal asegurado contra la mesa y abre la pantalla por completo.
-
-
-
Sostén la pantalla con una mano y usa la mano libre para quitar los seis tornillos Torx T8 que sujetan las bisagras.
-
-
-
Asegura firmemente el cuerpo principal de tu MacBook con una mano.
-
Con la mano libre, empuja el lado izquierdo de la pantalla hacia arriba y hacia la parte inferior de tu computadora portátil para liberar la bisagra izquierda.
-

I followed all the steps and my new screen is working properly (•̀ᴗ•́)و. I realized however that my Touch Bar isn’t lighting up anymore… Did I forget to connect something?
Where did you buy a replacement screen for your Mac? I can seem to find any for the A1989 Model that seems legit and I’m not sure how much I trust eBay listings.
Did you ever find an answer to this because I have had the same thing happen and I cannot for the life of me figure out why it has happened, what did you do to fix the problem or did you just give up and go to apple?
jack -
Unfortunately, my Touch Bar is still not working. I did some research back in 2020 and couldn’t find anything that would help fix this issue. And since my laptop is connected to an external screen and keyboard most of the time, it never really bothered me. But I should take it to Apple to see if it can be fixed and how much it’ll cost…
Guy -
I mean you may as well because what if it is just some simple calibration issue or some silly little thing that their diagnostic software can fix in less than a minute? If they try to charge too much money then you can always just deny, I believe that I will end up doing that soon to get a quote on just how much it will cost me to get both the display and Touch Bar repaired and see if it is worth it or not.
jack -
Ok so I would like to inform you that I did a little bit of digging into my MacBook Pro with its Touch Bar connectors and I have made the discovery that 1 one of those little chips near the connector I think they are resistors or diodes, idk but I found that one of them have literally exploded and killed another one next to it. I have no idea why or how but maybe you wanna check your MacBook Pro for that as well to see if its a common occurrence
jack -
I think you didn't read the VERY IMPORTANT comment by Marcelo on step 30. The long rectangle next to the pointy part of the "left" hinge (the one visible in the photo) is the connector for the touch bar and is EASILY DAMAGED, especially since you need a lot of force to get the hinge in.
I got around this by sliding the "left" hinge SIDEWAYS into its slot and then forcing the "right" hinge back.
Does anyone know where I can find a new official Apple Display 13” for model A1989? Can’t seem to find any except for eBay.
Yeah, I found mine on eBay. This vendor seemed trustworthy (www.ebay.com/usr/wallachee?_trksid=p2060353.m1438.l2754) and it turned out to be true. The screen I got is working perfectly…
Guy -
I also had an issue with Touch Bar not working after the screen replacement, everything else works fine though.
Has anyone been able to figure out what causes the “TouchBar not working anymore” issue?
Like I asked the other guy, did you ever manage to find a fix for it? Because I am too having this issue
jack -
me too got the a1989 13” macbook pro. replaced the screen and touchbar screen is there but unresponsive to touch
I have the same issue but mine is due to me damaging a little chip near the connector. Maybe check your board over and make sure you didn't damage any chips in the process like I did
jack -
Can the MBP 13 intel Touch Bar work without the screen ? Like an Apple II
What happened if I left the screen connector unplugged ?
It does work, I did this with my own Mac and you can remove the screen and keep the functionality of the touch-bar. What you will loose is keyboard backlight so make sure that the brightness in software is at 100% for the touch-bar to be full brightness cos that won't change when you take the screen off
jack -
For people who had problem with the touch bar. Basically, the connector was damaged in the process of changing the screen.
Fan will not stop running after screen replacement. Tried resetting smc. No luck. Please advise. Thank you. MJ
I got the fan to stop but the Touch Bar no longer works.
please advise.
Pefekte Anleitung, Neues Display (auch die Touchbar) funktionieren wie Neu 😅😇 Danke 🤓
I swaped the screen following the 'purple gate' now my mbp is not booting anymore 😣 i checked twice every connections, all seems good... Any advice?
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=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.
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.
