This serves as the starting point for every repair on your MacBook Pro: remove the lower case for access to internal components.

For your safety, drain your MacBook Pro's battery below 25% before you begin this procedure. A charged lithium-ion battery can create a dangerous and uncontrollable fire if accidentally punctured.

  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. 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

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

    • Use a P5 Pentalobe driver to remove the six screws securing the lower case:

    • Two 6.2 mm screws

    • Four 3.4 mm screws

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

  2. 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.

  4. 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. This releases the first of the hidden clips securing the lower case to the chassis. You should feel and hear the clip pop free.

  6. 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.

  7. 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. It may help to pull first at one corner, then the other. In case you aren't able to separate the clip from the lower case you can apply a suction cup next to the corner with the clip and carefully use it as a pulling handle.

So how does one re-affix the clips when it’s time to replace the bottom case?

Yeah, Ifixit is SOOOOO great except for explaining reassembly steps that don’t just involve ‘reverse order’ like this %#*@ bottom case. I did a whole display (yay me!) and am now stumped as to the last step of reassembly. If you just put it back on and put the screws back in, there’s an increasing gap from the rear 2 screws to where the display hinge begins (that sits flush before taking it off). There seems to be no ‘popping’ it in place and the pegs on the underside of the cover are in the middle.
