    • 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:

    • 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

    • Completely power off and unplug your MacBook Pro before you start. Close the display and flip the entire laptop upside-down.

    • Use a P5 Pentalobe driver to remove six screws securing the lower case, of the following lengths:

    • Four 4.7 mm screws

    • Two 6.6 mm screws

    • Note how the screws come out at a slight angle—you must reinstall them the same way.

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

    • Repeat the previous step on the other side, using an opening pick to to release the second clip.

  6. MacBook Pro 15" Touch Bar 2018 Logic Board Assembly Replacement: passo 6, imagem 1 %32
    • Lift the front edge of the lower case (the side opposite the display hinge) enough to slide your fingertips underneath and get a good grip on it.

    • Two additional hidden clips near the middle of the cover should pop free at this point, if they haven't already.

    • Don't lift more than an inch or so, and don't try to remove the lower case yet.

  7. MacBook Pro 15" Touch Bar 2018 Logic Board Assembly Replacement: passo 7, imagem 1 %32 MacBook Pro 15" Touch Bar 2018 Logic Board Assembly Replacement: passo 7, imagem 2 %32 MacBook Pro 15" Touch Bar 2018 Logic Board Assembly Replacement: passo 7, imagem 3 %32
    • Pull firmly to slide the lower case towards the front edge 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.

    • Pull to the side—not up.

    • This may require a lot of force.
