-
-
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.
-
-
-
Repeat the previous step on the opposite side, sliding your opening pick under the lower case and up the side to pop the second clip free.
-
-
-
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.
-
-
-
Pull the lower case firmly towards the front 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.
-
-
-
Remove the lower case.
Why does this show a logic board with 2 fans? Mine has only 1 fan.
If yours only has one it’s the 2 thunderbolt model from another year or a MacBook Air of some sort:-)
-
-
-
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.
-
-
-
Gently peel back the small piece of tape covering the battery board data cable connector.
-
-
-
Disconnect the battery board data cable by sliding it out from its socket.
-
Slide parallel to the logic board, in the direction of the cable.
Would be nice to mention the fact you have to lift up the tiny little plastic cable locking device before pulling this ribbon cable out.
-
-
-
Fold the battery board data cable to the side and out of the way.
-
-
-
-
Use a T5 Torx driver to remove the 3.7 mm pancake screw securing the battery power connector.
-
-
-
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.
-
-
-
Use a T3 Torx driver to remove the two 1.8 mm screws securing the trackpad cable connector bracket.
use a t4 for and push down hard the screw on the right, it feels like apple just fcks with us for no reason other than to make it harder to fix these things
Correct, T3 did not fit - had to use T4

-
Remove the trackpad cable connector bracket with a pair of tweezers.
-
-
-
Use a spudger to disconnect the trackpad ribbon cable by gently prying its connector straight up from the logic board.

-
Use a T3 Torx driver to remove the two screws.
-
Two T3 Torx Screws.
These are T3 on this machine I'm working on
Thanks for letting me know:-)
on the machine I was working on I was able to use a T4
But thanks again for letting me know
t3 on left and t4 on right
no shield or screws on my machine, just tape and a zif connector to flip up and disconnect
-
-
-
Carefully peel back the black tape to reveal the ZIF connector.
-
Unlatch the ZIF connector by flicking the arm on the connector upwards and carefully remove the cable from the connector by sliding it out.
-
Repeat this process with the newly revealed connector.
the bottom one is very very difficult good luck
make sure you click the piece up before moving the connector ribbons. you will hear a click.
-
-
-
Use a T3 Torx driver to remove the two screws.
-
Once the screw have been removed carefully remove the metal shield.
-
Under the metal shield there is a connector, carefully unplug it.
T3s on my A1989 here.
Thanks for letting my me know:-)
Il change the size
When I was taking my one apart I was able to use a T4
Thanks for letting me know:-)
sometimes t5 needed. ive used t3 and t4 and just before drilling another hole on a whim tried t5
you are missing a picture of the connecter being unplugged (last step on this) step 20

-
Use a T4 Torx driver to remove the two screws.
-
Two T4 Torx screws.
-
Carefully remove the metal shield.
-
The second cable you will disconnect will be lightly adhered so carefully slide a plastic spudger under it and finally unplug it.
Bear in mind Touch ID is paired to the logic board so if you're replacing the Touch ID along with the logic board, be sure to check the power Touch ID button is mounted correctly and can be depressed before you put the logic board back in. Otherwise you may find yourself taking the board back out again. Don't ask me how I know.
can we get pictures of the two connectors under the shield
The screws on mine appeared to be T3, not T4.
T3 on my emc3214 as well

-
Use a T3 Torx driver to remove the four screws.
-
4 T3 Torx screws.
-
Once the screws are removed carefully remove the metal shields.
-
Carefully unclip the connector.
Bei mir waren die beiden unteren markierten Schrauben nur mit einem Torx T4 lösbar. Außerdem sind sie länger als die oberen Schrauben, was beim Zusammenbau zu beachten war.
upper silver had T4 and thin black clip had T3 screws

-
Disconnect the cables carefully with a plastic pry tool.

Use a T3 Torx driver to remove the two screws.

So where is the touchbar connector on the actual 13 inch Macbook Pro logic board?
Mine is the A2159. This logic is not the one that mine is.

-
Use a T5 Torx driver to remove the two 2.3mm (3.7mm head) screws securing the heatsink.
The screw under the WiFi / Bluetooth antenna cables is slightly longer than the others circled in red, at least in mine. It makes sense as that location has the additional thickness of the metal shield piece that goes between the screw and the hole.

Congratulations you have now removed your MacBook's LogicBoard
You are actually removing the coolers as well, not only the main logic board.

Hi!
If anyone needs any help just ask me:-)
Thanks:-)
Bonjour, une fois la carte mère remplacer, comment remettre le nouveau numéro de série et bios à jour svp?
Salut, désolé pour mon mauvais français car j'utilise un traducteur pour cela :-) lorsque vous remplacez la carte logique/carte mère, la nouvelle carte aura son propre bios et son numéro de série, si vous voulez mettre à jour votre bios, il vous suffit de mettre à jour macOS
At what point would you say you need thermal paste?
You need to replace thermal past every 4years or so…or at least that’s what I do to keep the machine running cool:-)
What about the soft plastic rectangular, 3-sided pieces? Are those cooling guides, or just noise suppressors for the fans? Critical? I didn't see those addressed in your guide.
Is the Logic Board the same for all A1989 models? I have a Mac Book from 2018 and one from 2019 and I would like to transfer my logic board from one to the other, if this works.
Hi, Can I replace an A1990 (MBP 2018 15) logic board into an A1707 chasis (MBP 2016 15)??? greetings
