Introdução
Use this guide to replace the entire display assembly on your MacBook Pro, in order to fix a cracked or faulty screen.
For your safety, drain your MacBook Pro's battery below 25% charge before you begin.
Ferramentas
-
-
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 the six screws securing the lower case:
-
Two 6.2 mm screws
-
Four 3.4 mm screws
-
-
-
Apply a suction handle to the lower case near the front-center area of the MacBook Pro.
-
Lift the suction handle to create a slight gap between the lower case and the chassis.
-
-
-
Insert one corner of an opening pick into the space between the lower case and the chassis.
-
Slide the opening pick around the nearest corner and halfway up the side of the case.
-
-
-
Insert your opening pick once again under the front edge of the lower case, near one of the two centermost screw holes.
-
Give the pick a firm twist to pop free the third clip securing the lower case to the chassis.
-
Repeat this procedure near the other of the two centermost screw holes, popping the fourth clip free.
-
-
-
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.
-
-
-
Carefully peel up the large piece of tape covering the battery connector, on the edge of the logic board nearest the battery.
-
Remove the tape.
-
-
-
Use a spudger to gently lift the battery power connector, disconnecting the battery.
-
Lift the connector high enough so that it stays separated from its socket. If it accidentally makes contact during the course of your repair, it could damage your 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.

-
Remove the four 1.9 mm T3 Torx screws securing the plastic covers on top of the display hinges.
-
Remove both plastic hinge covers.
-
-
-
Remove the two 2.9 mm T3 Torx screws securing the aluminum cover on top of the main display cable.
-
Remove the cover.
-
-
-
Remove the two 1.7 mm T3 Torx screws securing the aluminum cover on top of the display cable flex connector.
-
Remove the cover.
-
-
-
Remove the four 1.5 mm T3 Torx screws securing the two aluminum covers on top of the two display board cables.
-
Use a pair of tweezers to remove the two aluminium covers.
-
-
-
Carefully disconnect the three antenna coax cables by prying them straight up from the logic board.
-
-
-
Use an opening pick to lever out the antenna cable assembly in the areas shown.
-
-
-
Carefully remove the antenna assembly, while simultaneously feeding the antenna cable bundle out from underneath the heat pipe.
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.
-
-
-
Remove the four 3.9 mm T3 Torx screws securing the two display cable cover springs.
-
-
-
Grab the left side of the display cable assembly and pull it towards the bottom end of the MacBook and away from the cover spring.
-
Use a pair of tweezers to pull the cover spring of the display cable out of its recess.
-
Repeat this step with the right cover spring of the display cable assembly.
-
-
-
Fully open the screen and stand your MacBook Pro up on one side.
-
While steadying the MacBook pro with your free hand, remove the three T8 Torx screws from the lower display hinge.
-
Remove the remaining three T8 Torx screws from the upper display bracket.
-
-
-
Push both halves of the MacBook Pro together so that the hinge brackets can be lifted clear of their recesses in the chassis.
-
Push the main body of the MacBook Pro away from you while pulling the screen toward you to separate it.
-
Remove the display/screen assembly, being careful not to snag it on any cables.
-
Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.
To reassemble your device, follow the above steps in reverse order.
Take your e-waste to an R2 or e-Stewards certified recycler.

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.
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…

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.

@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!

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(

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?

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
