Use this guide to remove the bottom cover, a.k.a. lower case—either to replace it, or to access other components in your MacBook Pro.
For your safety, discharge your MacBook Pro's battery below 25% before you begin this procedure. A charged lithium-ion battery can create a dangerous fire if accidentally punctured.

Four 4.7 mm screws
-
Two 6.6 mm screws

Press a suction handle into place near the front edge of the lower case, between the screw holes.
-
Pull up on the suction handle just enough to open a small gap under the lower case.

-
Slide the corner of an opening pick into the gap you just created underneath the lower case.
-
Slide the opening pick around the nearest corner and then halfway up the side of the MacBook Pro.

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

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.
-
-
-
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.

Remove the lower case.

Set it in place and align the sliding clips near the display hinge. Press down and slide the cover toward the hinge. It should stop sliding as the clips engage.

When the sliding clips are fully engaged and the lower case looks correctly aligned, press down firmly on the lower case to engage the four hidden clips underneath. You should feel and hear them snap into place.

What about a guide for replacing the SSD for more memory? Is this possible?
@eowyn327 Not possible on any of Apple’s current laptops. They want you to buy a new machine or pay them a monthly fee for iCloud storage, rather than have the ability to expand the internal storage. Only other option is to tote around an external SSD and a dongle. Sorry!
MacBooks 2018+ have soldered components and it is not possible to replace/upgrade them after the initial purchase.
When I opened the bottom case and shook it a little, it rattles a little as if something was loose. Is this normal? I didn’t actually open the case, just popped the clips and closed it back up.
I need to re-tap the threads on two of the lower case screw holes. Can anyone tell me what the diameter and pitch is?
