Introduction

Use this guide to upgrade or replace the solid-state drive in a MacBook Pro 13” Late 2012. This MacBook Pro uses a proprietary storage drive connector, and is therefore not compatible with common M.2 drives without the use of an adapter.

Before you perform this repair, if at all possible, back up your existing SSD. Then, either familiarize yourself with internet recovery or create a bootable external drive so you’ll be ready to install macOS onto your new drive and migrate your data to the new SSD.

Finally, we strongly recommend installing macOS 10.13 High Sierra (or a later macOS) before replacing the original SSD from your MacBook Pro. Most new SSDs require updated storage drivers not found in versions of macOS prior to High Sierra.

    • Remove the following ten screws securing the lower case to the upper case:

    • Two 2.3 mm P5 Pentalobe screws

    • Eight 3.0 mm P5 Pentalobe 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.

    If don’t have one of those neat project mats, then you can use small pieces of flattened blu-tack to hold the screws. If you arrange them in the shape of your mac book cover, and put the screws down methodically, you can get a one-to-one mapping of the screws to the correct screw holes.

    Or you can use an ice tray where you put the screws and the parts in separate bays in the same order as they come in the instructions.

    This is great! I used a small magnetic white board, and wrote on it to identify the parts as I went. This whole process, from the fast shipment to the great instructions to the complete, high quality, tool kit has been great. I’m typing this comment on my resurrected laptop. Thank you! Sue

    • During reassembly, gently push down the center of the lower case to reattach the two plastic clips.

    • The lower case is connected to the upper case at the center, with two plastic clips.

    • Remove the following screws securing the battery connector board to the logic board:

    • Two 2.8 mm T6 Torx screws

    • One 7.0 mm T6 Torx shouldered screw

    • Use tweezers to remove the small plastic cover located near the bottom right of the battery connector board.

    Is adhered to screw beneath, so lift firmly and slowly.

    when doing this with metal tweezers as instructed in the video, it was difficult to get off and apparently while i was trying to do it, the tweezers went too far under and i believe made contact with the screw underneath? there was a zzz noise, an orange flicker and a little stream of smoke that came out. i freaked out and put everything back together to see if the laptop even still worked, it turned on and everything but died right away (i drained it before doing the repair anyway, so i was surprised it turned on at all).

    i finished the battery repair and did several other things while in there. i have charged it all the way as recommended and will use it later on to see how everything is, im hoping that it’s a okay, but could someone explain to me what happened and the possible consequences?

    • Remove the wide head 6.4 mm T6 Torx screw securing the battery connector to the logic board assembly.

    • Carefully lift the battery connector board up off the logic board.

    • It is recommended to bend the battery cables just slightly, to keep the board suspended up above the logic board and out of the way.

    • Do not fold the board completely over, or crease the cables, as this may damage the battery.

    • Grasp the Interposer with tweezers.

    • An interposer is the name for an interface that links one electrical connection to another. In this repair, it is the board connecting the battery to logic board.

    • Lift the Interposer off the logic board and remove it.

    • Removing this board will ensure that the battery remains disconnected throughout your repair, preventing your computer from accidentally powering on. It's also a good idea to take it out so it doesn't fall out unexpectedly.

    How can I remove interposer I m not able to remove it

    you must lift it absolutely vertically, or it fouls against the locator pin in the corner- you can easily get the impression that it won’t come over the end of this pin- almost like it’s rivetted in. it isn’t. get a good grip on it with the tweezers in the centre hole & one of the sides, & lift it STRAIGHT up.

    • Use your thumb or finger to bend the plastic spring bar on the SSD tray, freeing the two clips at the front side of the device.

    • While holding the spring bar depressed, tilt the SSD assembly up out of its cavity.

    • Insert the edge of plastic opening tool between the SSD and the SSD tray, opposite to the socket side of SSD tray.

    • Pry the side of the SSD opposite the SSD tray socket out of the SSD tray.

    • Only lift the SSD up far enough to grab the sides of it with your fingers. Lifting it any more may damage the card or socket.

    • SSD remains.

    I want to buy external usb casing for this SSD card, could you please tell us if this is mini PCIe mSATA or something else.

    A most excellent step by step. I now need to figure out how to grant permission for my backup Air to read my removed Pro SSD files. Perhaps a link from here to that would be helpful.

I followed the guide and was able to upgrade my wife's MacBook from 128GB to 240 GB!

One thing I noticed was that when I removed the plastic clip in step 6, it left behind a glue dot on the screw head I had to remove in step 7. I wasn't sure why my screwdriver kept rotating until I realized the clear dot was covering the screwed! Then I tweeze the dot off, and put it in the recess on the underside of the clip and all was good.

Everything went to the letter after, until it came time to restart and initialize the new disk. It turns out the old disk had some directory damage, so when it was copied to the new internal SSD, then the Mac wouldn't boot from it until I did a couple FSCK and Repair Disk fixes.

Vignesh,

Sam,

The 2012 MacBook Pro uses an PCI Express Mini Card connection between the logic board and the SSD.

"Some notebooks (notably the Asus Eee PC, the MacBook Air, and the Dell mini9 and mini10) use a variant of the PCI Express Mini Card as an SSD. This variant uses the reserved and several non-reserved pins to implement SATA and IDE interface passthrough, keeping only USB, ground lines, and sometimes the core PCIe 1x bus intact.[11] This makes the 'miniPCIe' flash and solid state drives sold for netbooks largely incompatible with true PCI Express Mini implementations."

I fully agree, Especially as it turned out to be a little tricky to get the connector back in his position properly. Don't think there is a higher risk of damage through electric shock or so. Next time I will for sure skip it ;-)

Aren’t steps 4-10 completely unnecessary?

That’s what i thought too!
