将下壳体牢固地拉向MacBook的正面（远离铰链区域），以分离固定下壳体的最后一个夹子。
Tip: If you use a spudger as a lever, placing the thin end inside the hinge and pressing lightly towards the bottom casing, it pops out quite easily.
-
-
-
拆下底壳。
-
将其安装到位，并对齐显示屏铰链附近的滑动夹。向下按并将盖向铰链滑动。夹子啮合后，它应停止滑动。
-
当滑动夹完全接合并且下壳体看起来正确对齐时，用力向下按下壳体以接合下面的四个隐藏夹。你应该感觉到并听到它们卡入到位。
Hab zum Schluss das Blaue OpeningTool benutzt und am Rahmen in der nut eingehackt um den Deckel final hinein zu drücken. Da er per Hand nur bis zu einem gewissen Punkt geht

使用T5 Torx 螺丝刀，以删除3.7 mm 煎饼螺丝固定电池电源接口。
io ho trovato un Torx T4 invece del T5.
Ciao Stefano! Grazie per il commento. Infatti c’è sempre una certa tolleranza fra il cacciavite e la testa delle viti. Quindi è possibile che un cacciavite più grande o più piccolo sia più “comodo” in certi casi. Buona riparazione!
konnte diese Verbindung nicht lösen. Zu sehr angezogen

轻轻地断开电池接口，用小铲轻轻地拔出电池。
-
将接口抬得足够高，使其与插座保持分离。如果在维修过程中意外接触，可能会损坏 MacBook Pro。
Please save yourself a pile of money and read this before doing this step: I bricked my MacBook by not being extremely careful and making sure to NOT touch the connector together as I took it apart. Ouch ouch ouch. 😫

拧下将铝盖固定在显示屏电缆柔性接口顶部的两颗1.7毫米T3 Torx梅花螺丝。
-
取下盖子。
I have done 2 these these exact same 2019 MacBooks now, and both times The screw on the right seems to not be a T3. At first it appeared that I stripped it, but once I got to the second one and I was very gentle with it, it’s a totally different screw. And I can’t figure out what it is… But the T3 or the T4 will not remove it. Neither will a Pentolope. I just removed the left screw, and then I pivoted the cover away so I could remove the connecter. Anyone else having this issue?

You’re right, noahmadsen, they’re super slightly, but different.

卸下将两个铝盖固定在两个显示电缆接口顶部的四颗1.5毫米T3 Torx螺丝。
-
用镊子卸下两个铝盖。
FYI.....during reassembly, the new screen may come with these already attached so compare the old screen to the new one before installing.

使用三角撬片在所示区域撬出天线电缆组件。
I stripped these, is there any tips on getting these out?
Mark, here's a guide with tips for removing stripped screws. Hope it helps—best of luck!

卸下天线电缆组件。
After doing the job the first time, when I opened the display there was something clicking loudly. I had found out that this antenna assembly wasn’t put back properly. When reinstalling this, there is a flat metal piece on the bottom centre of the antenna assembly. Mine became bent for some reason. I had to bend it back straight. It needs to click back in to top case. Problem solved!
noahmadsen - 回复
Same happened to me, there’s a small canal in the top case where the antena must be vertically inserted, if you just push it horizontally in place it will fit and you will be able to reassemble the computer, but the antenna will be sligthly bent and cause friction with the screen when opening.

拧下固定两根显示电缆弹簧铰链的四颗 3.9 mm T3 Torx 螺丝。
T4 worked best for me

-
-
将 MacBook Pro 的两半推在一起，以便可以将铰链支架从机箱上的凹槽中提起。
-
将MacBook Pro的主体向你推开，同时将屏幕拉向自己以将其分开。
-
卸下显示屏/屏幕部件，注意不要将其挂在任何电缆上。
When reassembling, make sure to align the back edge of the new display assembly (hinge side) with the edge of the MacBook body, then tighten the hinge screws. Misalignment can cause the MacBook to open and close improperly. It should feel smooth where the gaps are between the two halves.

Why does the guide suggest purchasing the "MacBook Pro 13" Retina (A1708, A2159) Display Cable "
Replaced my display with a genuine used panel and the true tone still worked. However, be very careful of the touchbar flex.
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.
Macrepair SF - 回复
@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>
Cool_Breeze - 回复
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.

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
richardjgreen - 回复
If you have a damaged screen you can still use a converter from thunderbolt (USB 3) to HDMI and plug your Macbook Pro to your TV as monitor display. Just make sure to chose the right Source (HDMI IN) in your TV. I did it and to make it work I unplug and plug again in my Macbook and so I could disable the Auto boot

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 - 回复
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 - 回复
running `nvram -p | grep 'AutoBoot'` in terminal verifies that it was accepted
result: `AutoBoot %00`
Marek Polák - 回复
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.
Grant Ormsby - 回复
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 - 回复
I've just received my replacement battery and it reads 0,042V between the two main connectors. Do you think it's dead?

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 - 回复
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.

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

Excellent instructions. I was able to follow and install the new screen. I recommend that you get a good set of tools before you begin. I started with an inexpensive repair kit bought online. The Penta and torx bits failed. I bought an IFIXIT kit with quality bits and I was able to do everything I needed.

If you're not running an admin account the sudo command won't work (which honestly, you should not be running admin). Rather than logging in to your admin amount via the OS, in the terminal type "login [admin username]," then the password and you'll be able to do the sudo command as described above. Once you're complete, type "logout [admin username]" and you'll be good to go. Obviously replace [admin username] with whatever the account name for your admin user is.

For those unable to complete this step because the screen is too damaged I recommend leaving your macbook on until the battery dies.

Just replaced my 2018 15" MBP battery. Running Sonoma.
I found no way to disable AutoBoot (The status can be checked in the Power section of system report).
Anyway, i left my battery completely drain before opening the MBP, and had no issues during the process.
Cédric Bontems - 回复
After sending this command in terminal when I checked what happens if I now open the lid, instead the screen lit slightly up (still black) then a battery symbol showing the charging state showed up.
Now, after replacement of the battery, this is all I get to see.
No reset of NVRAM nor PRAM helped.
Currently the new battery charges (58% atm) and it feels like it‘s mocking me.

I suspected the keyboard or TouchID sensor wouldn’t work, so I went on and checked every connector.
I missed connecting the left TouchID sensor from step 31.
