Introduzione
Segui questa guida per rimuovere il trackpad, per sostituirlo oppure per poter accedere liberamente alla batteria.
'''Per la tua sicurezza, scarica la batteria del tuo MacBook Pro sotto il 25% prima di iniziare. Se forata inavvertitamente, una batteria al litio-ioni può causare un incendio pericoloso incontrollabile.
Strumenti
-
-
Accendi il tuo Mac e lancia Terminal.
-
Copia e incolla seguente comando (oppure riportalo esattamente) in Terminal:
-
sudo nvram AutoBoot=%00
-
Premi [return]. Se richiesta, inserisci la tua password di amministratore e premi di nuovo [return]. Nota: il tuo tasto return può essere etichettato anche come ⏎ o "enter."
-
sudo nvram AutoBoot=%03

Usa un cacciavite pentalobe P5 per rimuovere le sei viti che fissano la cover inferiore, delle seguenti lunghezze:
-
Quattro viti da 4,7 mm
-
Due viti da 6,6 mm
-
-
-
Tira la cover inferiore con decisione verso la parte anteriore del MacBook (allontanandola dal lato con le cerniere) per separare l'ultima delle clip che trattiene il case.
-
Tira prima da un angolo e poi dall'altro.
I found it easier to insert a screwdriver through the hole (not too far down), and use that to pull sideways, as it was hard to get a strong grip with my fingers.
If you have a black stick, or a nylon probe tool, you can insert it at the back at the point closest to the screw holes, and use that to push the lower case forward. I’ve seen this help me quite a few times, and it makes it quite easier.
I like adrianbrown's suggestion. Spot on!
Its difficult if the side catches arent released properly, check them again if it seems too much.
I snapped one of the spring loaded logic board grounding pins. Take your time. Leverage from the back in order to push it out versus pulling on it.
Take the opening pick and stick the edge down behind the hinge all the way to one side, so it is perpendicular to the case, and give it a twist. That end should pop free. Do the same on the other side and there you go.

-
Rimuovi la cover inferiore.
-
Disponilo in posizione e allinea le clip a scorrimento vicino alla cerniera del display. Premi verso il basso e fai scorrere la cover verso la cerniera. Lo scorrimento si dovrebbe arrestare non appena le clip si agganciano.
-
Quando le clip a scorrimento sono perfettamente agganciate e la cover sembra correttamente allineata, premi con decisione la cover stessa per agganciare le quattro clip nascoste. Dovresti sentire lo scatto quando le clip si bloccano.
I am doing a battery replacement for a client on this model. The battery has swollen more than I have ever seen before on a Mac! Roughly a ½” higher, once cover removed. Cover was so tight that one screw stripped and had to drill out one screw after trying everything else! Fortunately, I’m an exmechanic/machinist and I own a full size drill press! None of the screw extraction tools sold by ifixit worked or were applicable until I finally got the cover off. Then the small screw pliers from Japan were easier to use than anything else I own. My tools are mostly for larger nuts, bolts and screw extraction. Possibly a mini hammer driver screwdriver would work if one could be made small enough for tiny screws! Ross

Solleva e rimuovi la grande cover rettangolare della scheda della batteria, sul bordo della scheda logica dalla parte più vicina alla batteria.
-
Se la cover non si stacca facilmente, applica una modesta quantità di calore con un iOpener, un asciugacapelli o una pistola termica per ammorbidire l'adesivo sottostante e prova di nuovo.
What is the though behind this step? I have replace my trackpad before, and I did not do this step. At the time, there was no guide. As a result, I’m wondering how this changes/or if it is necessary for the repair process.
It’s necessary in order to disconnect the battery. Always disconnect the battery before making repairs.
I found my one of my fan making some noise, when open the bottom of my Mac I see this piece floating over the fan. Trying to put it back where it goes but don’t seem to stick anymore and move around. Does this piece is really necessary or I can simply remove it or order a new one from you?
It should be pretty easy to reattach. Put a dab of rubber cement or a bit of double-sided tape on top of each of the screws underneath the cover, press the cover down, and close up your MacBook. It should stay put. Don’t use superglue or anything else that will harden over the screw heads and make it impossible to fit a driver in there later.
Do you know if this piece is necessary. I lost mine.
My Macbook doesn’t appear to even have this piece.

Stacca il nastro adesivo che copre il connettore del cavo dati della scheda della batteria.
The replacement battery did not come with the “tape” in this cable so it was very difficult to reinsert the cable into the zif socket. Now I can’t get the replacement battery to charge.
I have the same issue, My battery is not charging. Did you figure out how to get your battery to charge?
In my case, the original replacement was faulty. iFixIt sent an RMA without hesitation, and I am happy to report that the new one works fine. But also recheck this step and steps 13/14.
J D -
I was able to reinsert the cable easily a number of times with the nice Ifixit angled tweezers as the ziff connectors tiny latch came off! I ended up using a bit of Pliobond 25, contact cement to mke sure the data cable doesn’t move. A future repair will just pull off or at most need an xacato blade knife to slit the rubbery cement. Ross
REALLY important. You need to really pull this back in snug for things to work when you reassemble.
I didn’t seem to have any tape covering it, I just proceeded to the next step

Usa uno spudger per alzare delicatamente la linguetta di bloccaggio del connettore ZIF del cavo dati della scheda della batteria.
Mein Sicherungsbügel ist abgebrochen, oder zumindest nicht mehr auf dem ZIF-Stecker. Ist dieser Sicherungsbügel sehr wichtig, oder kann ich das Kabel dennoch zurück stecken?
Hallo Fabio, wahrscheinlich wird das Kabel ohne den Bügel nicht mehr halten. Das Zurückstecken geht, aber es bleibt nur sehr fragil drin.
My zif connector was already open. It apparently never got closed during manufacture. Being so tiny this made it difficult to see why there was nothing to pry up with the spudger. Once I put my finger on top of it I realized the flap was already verticle.

Scollega il cavo dati della scheda della batteria facendolo scorrere fuori dal suo zoccolo.

Tira rimanendo parallelo alla scheda logica, in direzione del cavo.
If this breaks, what’s the risk to the computer?
I tried powering mine on after my zif connector socket broke. It made bad electrical noises. I had water damage at one point and cleaned the unit very well but never replaced the battery. Through excesive, a hot and bad battery, or water damaged weakening the area mine came right off with the tape when i peeled it up. Im working on finding the part and will attempt to solder it back. Of course i still need a battery which ours was swollen. After water damage it worked great for over a year though.
Mine broke and now the Macbook will not power on, this was after a battery replacement, the Macbook powered up afterwards, but after transporting it, it would not power up. I removed the back cover and noticed the battery board cover was missing and the zif gate for the battery data connector was half off.
Same here, I broke the cable which was soldered on the mainboard. I tried to hold it on place with a tape, but I couldn‘t charge my macbook though. Then I tried to solder it and I also failed. I wish I had read the comments before :/
I couldn‘t find the fpc 6 pin connector with 0,5 mm grid. However I managed to connect the flex cable directly on the mother board with 0,3 mm isolation filament! It was tough but I‘m so happy that it works again :)
Would you be able to give a little instruction on how you were able to make this work? I’m super curious and need a solution to the same issue.

Usa uno spudger per sollevare delicatamente il connettore dell'alimentazione della batteria, scollegando la batteria stessa.
wondering if i didn’t heed this warning close enough. mac not powering on. only black screen with battery and lightning bolt beneath it. What happens if this connector makes contact?
im in the exact same boat right now.
Was everything okay in your case?
Same here until I realized that I never reconnected the tiny power button/Touch ID connector in step 31! It’s underneath the headphone cable jack from step 30. Mine was hiding under the board and I carefully fished it out with a tweezers.

Hi, did you manage to fix this? Ive got the same issue sadly.
-
-
-
Usa un cacciavite Torx T3 per rimuovere le due viti da 1,9 mm che fissano la piccola cover di supporto del cavo del trackpad.
-
Rimuovi la cover.
T3 doesn’t seem to fit, somehow on my a1707 the driver doesn’t grip and it just slips on the screw.
What am I doing wrong?
I don’t have a T2 to try, what can I do?
I managed to get a holt of a T2, but still no luck: there are a bunch of screws that seem to be T2 but everything I stick inside them just spins around and doesn’t grip :(
T4 worked perfectly

-
Applica una modesta quantità di calore al cavo a nastro del trackpad per ammorbidire l'adesivo che lo tiene fissato alla batteria.
-
Puoi usare un iOpener, un asciugacapelli o una pistola termica, ma in ogni caso stai attento a non surriscaldare la batteria. Il cavo deve essere caldo, ma non al punto da non poterlo toccare.
I used a hairdrier. Barely needed to hold it there for 20 seconds before I could peel it off.
-
-
-
Stacca con cautela dalla batteria il cavo del trackpad e spingilo dove non dia fastidio.
In my case the sticky part of the track pad ribbon remained on the battery. So after replacement the trackpad ribbon does not have a sticker to stay on the battery.
Did it work all right without the adhesive there?
That happened to me too! I thought that was what was supposed to happen, until I read your comment. I managed to peel it off the battery, but before I could catch it it rolled up into a tight ball. I got about half of it unrolled and onto the ribbon.

Fai ruotare lievemente il display per aprirlo, ma lascia capovolto il MacBook. Il gruppo trackpad dovrebbe separarsi e rimanere di piatto sul display.
-
Sfila delicatamente il cavo a nastro del trackpad attraverso la sua feritoia nello chassis.
WARNING - READ THE NEXT STEP NOW OR YOU WILL LOSE THE WASHERS. Please update this with BIG RED LETTERS in the step to indicate what is about to happen, or you’ll skip forward and the washers will fly everywhere. I’m really upset right now.
-
-
-
Mentre rimuovi il gruppo del trackpad, stai molto attento a non perdere le nove piccole rondelle metalliche sopra gli alloggiamenti delle viti. Non ci vuole davvero molto a farle volare via e a perderle.
-
Rimuovi il gruppo del trackpad.
They are not kidding about the jumping washers.
Pro Tip: put your magnetic mat under the trackpad as you slide it out to catch the tiny washers. Alternatively, a magnetic tool bowl, or a terry cloth towel so the lighter guys can’t get far if they fall.
Can I change the battery with out removing the trackpad and logic board?
yep lost a washer in the process

Is there any way to fix the track pad without having to replace it? I think I got some tea spilled on it. So right bottom corner does not flex/click.
Unlike the older Trackpads the newer Touchpads use a Taptic engine (the coils along the bottom) for the click action to give you the feel of the depressing the pad.
Sadly, you can’t really fix these as they get jammed up with what was spilled and you can’t soak the pad in anything as that would ruin it. Damed and double damed!

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 - Replica
@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

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.

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