Giriş
Use this guide to replace the entire display assembly on your MacBook Pro, in order to fix a cracked or faulty screen. This assembly also includes the integrated ribbon cables that are known to fail as part of the “FlexGate” defect on earlier models, so replacing it will also resolve the “stage lights” effect and other issues resulting from ribbon cable damage.
Although we’ve successfully tested this procedure on 2018 models using original Apple replacement displays, Apple’s T2 chip may prevent aftermarket displays from working correctly, and your MacBook Pro may not boot as a result.
For your safety, discharge your MacBook Pro's battery below 25% before you begin. A charged lithium-ion battery can create a dangerous and uncontrollable fire if accidentally punctured.

Power on your Mac and launch Terminal.
-
Copy and paste the following command (or type it exactly) into Terminal:
-
sudo nvram AutoBoot=%00
-
Press [return]. If prompted, enter your administrator password and press [return] again. Note: Your return key may also be labeled ⏎ or "enter."

sudo nvram AutoBoot=%03

Use a P5 Pentalobe driver to remove six screws securing the lower case, of the following lengths:
-
Four 4.7 mm screws
-
Two 6.6 mm screws
-
-
-
Pull firmly to slide the lower case towards the front edge of the MacBook (away from the hinge area) to separate the last of the clips securing the lower case.
-
Pull first at one corner, then the other.
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.
-
-
-
Remove the lower case.
-
Set it in place and align the sliding clips near the display hinge. Press down and slide the cover toward the hinge. It should stop sliding as the clips engage.
-
When the sliding clips are fully engaged and the lower case looks correctly aligned, press down firmly on the lower case to engage the four hidden clips underneath. You should feel and hear them snap into place.
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).

-
Peel up and remove the insulating sticker covering the battery board, on the edge of the logic board nearest the battery.
-
If the cover doesn't peel up easily, apply mild heat with an iOpener, hair dryer, or heat gun to soften the adhesive underneath, and try again.

-
-
Peel back any tape covering the battery board data cable connector.
-
Use a spudger to gently pry up the locking flap on the ZIF connector for the battery board data cable.
-
-
-
-
Slide the battery board data cable out of its socket on the battery board, and remove it completely.
Bonjour, super Tuto, petite question elle sert a quoi cette nappe , et quesqui se passe si elle est pas branché ?

Remove the display board flex cover.
T3 or T4? I almost damage the screw trying with the T3.
I’d say T4 as T3 was definitely too small

where can I purchase an lcd screen for this computer?
hai jeff. Is that possible I can revive my screen not to buy a new one, instead of replacing 3 pairs of flexible cable? thanks
To reiterate Ron’s request - you’ve shown me how to fix the screen (thank you!) without showing me where/how to purchase the replacement?
Banggodd or AliExpress but ta
Apple sry to get a genuine Apple screen as ‘compatibles’ may not pass in built Apple security- more expensive but can save a lot of heartache and later expense.
For everyone looking for screen replacements the short story is you cannot get them. Apple has prohibited their source from selling the assemblies to third parties. 3rd parties attempting to make their own have had them seized by customs. The only way to get one at this current time is from another device. However you may have issues using a display from another laptop even if it is the exact same model as apple will notice it is an unauthorized repair. This is a textbook example of apple’s illegal practices in regards to right to repair. You can read more about this here https://uspirg.org/feature/usp/right-rep...
Does anyone know if you can remove the MacBook screen and just use the keyboard mouse pad etc and connect to a monitor screen without attaching back a new screen? Thanks!
I changed the screen following this guide. The screen works but the camera of the new screen does not work and the backlight of the keyboard its not working (when turning on the computer the lights of the keyboard works but after login in with my password the backlight stops working). I tried nvram reset and pram reset and the problem is still there. If someone knows something about this please help me!
what is the part number for the screen?
Hi, I tried to repair/check my 2018 mac 15”screen and when I finished i cant get the mac to charge… have I broken the dam thing? battery flat?
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.
lamajr - Yanıt
@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.

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>

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 - Yanıt
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?

Not able to do that with damaged screen

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 - Yanıt
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 - Yanıt
running `nvram -p | grep 'AutoBoot'` in terminal verifies that it was accepted
result: `AutoBoot %00`
Marek Polák - Yanıt
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.

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