Use this guide to replace the trackpad assembly in your Retina MacBook 2017. This assembly includes the trackpad and the Haptic Engine.

  1. Before starting this procedure, you must disable your Mac's Auto Boot feature. Auto Boot powers on your Mac when you open the lid, and may be accidentally triggered during disassembly. Use this guide or follow the abbreviated instructions below to disable Auto Boot. This command may not work on all Macs. Power on your Mac and launch Terminal. Copy and paste the following command (or type it exactly) into Terminal:

    • 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."

    • You can now safely power down your Mac and open the bottom case, without it accidentally powering on.

    • When your repair is complete and your Mac is successfully reassembled, re-enable Auto Boot with the following command:

    • sudo nvram AutoBoot=%03

    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!

    Jeff Suovanen -

    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>

    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.

    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.

    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

    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

    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.

    • Before proceeding, unplug and power down your MacBook. Close the display and lay it on a soft surface, top-side down.

    • Remove the following eight screws securing the lower case:

    • Two 1.8 mm P5 Pentalobe screws

    • Four 2.9 mm P5 Pentalobe screws

    • Two 6.1 mm P5 Pentalobe screws

    • Note the orientation of the screws as you remove them—they need to be reinstalled at a slight angle.

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your device.

    IMPORTANT. You’re not removing the bottom, yet. This step is solely to separate the panel from its clips, permitting inside access.

    Chris Leeds - Contestar

    The screws go in tangent to the curve of the case. If you aren’t used to handling small hardware try turning the screw counterclockwise while you feel for the hole until you feel it drop, that means the threads have aligned. It takes only light finger torque when they are threaded correctly

  2. Wedge your fingers between the upper case and the lower case, starting from the rear of the MacBook between the hinges. Lift the lower case only slightly to avoid damaging the cables that connect the lower case to the upper case. Keeping a firm grip, lift steadily until the lower case separates slightly from the upper case.

    • Lift the lower case only slightly to avoid damaging the cables that connect the lower case to the upper case.

    • Keeping a firm grip, lift steadily until the lower case separates slightly from the upper case.

    • You may experience a lot of resistance when lifting the lower case. If necessary, slide an opening pick or other ESD-safe pry tool down the side edges of the lower case to pop the two hidden retaining clips free.

    • During reassembly, to re-engage the clips, press firmly near both side edges of the lower case (near where the pick is inserted in the third image) until you hear the clips snap into place.

  3. While holding the lower case in place, carefully flip the MacBook over so the Apple logo faces up.

    • It may be helpful to prop the MacBook open in this position for the next step.

  5. Use the flat end of a spudger to press and hold the small gold 'battery disconnect' button. If the power LED is lit up, continue holding the button until the LED goes dark, and then release. This may take up to 10 seconds. If the LED does not light, release the button after 5-10 seconds. Press and hold it again for 5-10 seconds, and release. Finally, press and hold it a third time for 5-10 seconds, and release.

    cannot turn on the led after replacing the new screen, even after following the turn on instructions upper…

    Laurent Pierre - Contestar

    on reassembly, I had to plug my laptop in to reactivate the LED light

    aaron_vandyke2003 - Contestar

    Does anyone know how to turn it back on..? I plugged the laptop in and saw the LED Light, but it won’t turn on

    mmcsorley - Contestar

    After reassembly I could not restart my MacBook using the power button or after SMC reset (shift-ctrl-option-pwr). I had to connect my MacBook to its charging cable to get the battery LED to re-illuminate. After that it was all normal.

    Richard Lovatt - Contestar

    It took a few minutes on the power adapter for my computer to turn on after it was reassembled.

    Luk Chl - Contestar

    mine doesnt turn on w anything, i forgot to click the buton to disconnect :_/

    cristian.campuzano - Contestar

    Same issue as above peeps. Followed ifixit directions verbatim and wasn't getting anything after screwing everything back in. Plugged in original 45W power block and waited, after few minutes battery LED came on and a min. or two after that, was able to get screen to turn on. Hope this helps somebody else.

    Brandon Elliott - Contestar

    May I ask how to get screen to turn on. I cannot get it work..

    Xiubo Zhang - Contestar

    There needs to be mention of procedure for getting the repaired MacBook to power up again after the repair is completed.

    I also am running into the issue described by others. MB will not come on again, even after being plugged into power and performing an SMC reset.

    Kinda stuck….

    Carlos Perez - Contestar

    Hi, I tried everything and my MacBook will not start up after replacing the bottom case with a battery installed. I decided to put back on the old case with the battery that needs servicing and it still will not power on. I am fairly experienced taking apart laptops I was an Apple service tech for 15 years. this has me baffalled. Any hints BTY the logic board does not show any power coming from the AC charger the power LED is not lit up

    • Add a piece of tape near the track pad to secure the upper case and prevent accidental movement.

    • It's possible to open the MacBook all the way and lay both sides down flat, but this may damage the flex cables and is not recommended.

  12. Remove the single 2.9 mm T5 Torx screw securing the battery connector to the logic board.
    • Remove the single 2.9 mm T5 Torx screw securing the battery connector to the logic board.

    From my experience it’s important to carefully press and hold the small button above left of the Battery Discharge label. Use a plastic spudger or finger tip. The illuminated yellow LED to the right will go off. I believe this discharges remaining electricity from logic board protecting it during repair.

    * I cannot find any documentation to support this, but I have damaged boards by not including this step.

    Chris Leeds - Contestar

    What is with the all plastic end of this cable that appears to just be glued right on top of its connector?

    Does the new one just stick back right on top?

    (In this photo it is the bottom side of the cable below the white water indicator sticker)

    Elizabeth Erkelens - Contestar

    • As an added precaution, you may physically disconnect the battery by inserting a battery isolation pick between the logic board and the battery connector.

    What happen if you don’t disconnect the battery? I didn’t and I saw smoke coming out when I connected the pad flex cable and the computer still started up

    DSANTIAGOSOY - Contestar

    If you don’t disconnect the battery you might accidentally short something on the logic board since power is still running through everything while you’re working on it. You can complete the repair without disconnecting the battery, but you risk accidentally breaking your logic board. It’s much safer to keep the battery disconnected while you’re working.

    This may require a T4 for the MacBook Retina early 2015. A T3 was too small, but this machine already had a replacement keyboard and body due to Apple recall. Just be aware.

    I should read this comment. I think my Mac Book have T4 screws. Thanks a lot.

Why do you need to disconnect the audio jack and USB-C port?
