    • Remove the following pentalobe screws securing the lower case to the MacBook Pro:

      • Eight 3.1 mm

      • Two 2.3 mm

    The number of screws listed here is wrong on my model. I had four of the smaller size.

    Just to add to my comment above (I can't edit it because it's anonymous), my MacBook Pro is a mid-2015 15in model 2.8GHz (A1398; EMC2881). For the bottom case it uses six 3.1mm screws, and four 2.3mm screws at the clutch/hinge side of the MacBook Pro. I tried using a 3.1mm screw at the clutch/hinge end, as described in the main article, and they don't fit. It has to be four 2.3mm screws.

    Removing the screw will void warranty?

    Ok, so here is what I discovered. There is no mobile application for these instructions, while having them on a computer is nice but when the computer you have is the one you are changing the battery on these instruction are of no use. I advise coping them and then paste them in PDF and print them out. Or you better have a photographic memory. I’m just saying.

    • The lower case has two plastic pegs (red) that fit into plastic clips in the upper case (orange).

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

    pretty hard to put it back, so I just remove the clips on the upper case....

    The trick to putting it back on is to guide your fingers to the same level as the clips, and then when you put the case down move your hand from the left side of the case to the right side of the case; applying pressure when you reach the area where the clips are.

    • Peel back the sticker covering the battery connector.

    You only need to remove the tape to the edge of the flap. This is enough to be able to pry the battery connector up.

    • Gently lift each side of the battery connector to pry the connector out of its socket on the logic board.

    • Bend the connector back toward the battery, ensuring that the battery connector doesn't accidentally make contact with the logic board.

    why is this necessary to remove a hard drive?

    @lawrencetaylor On any electronics repair, you need to disconnect all sources of power before you start. It’s a basic safety precaution and also removes the risk of accidentally shorting a connection somewhere (which can potentially kill your MacBook).

    • Remove the single 2.9 mm T5 Torx screw securing the SSD to the logic board.

    • Lift the end of the SSD up enough to pass over the speaker directly behind it.

      • Do not lift the SSD too high, or you could damage the contacts or socket.

    • Pull the SSD straight out of its socket on the logic board.

To reassemble your device, follow these instructions in reverse order.

So guys, I got a couple of questions:

1. Is this model (MBP Retina Mid 2015/MacBookPro11,4 ) really upgradable? says otherwise.

2. Samsung 850 EVO or Samsung 850 PRO would work with the model mentioned above?

Eduardo Delai Correa - Reply

Yes, it is upgradeable. At the time that article was published there was no drive on the market that would work. Now there is. No the Samsung 850 EVO or Pro would not work. As far as I know OWC is the only one that produces an after market drive that is compatible.

Chris Matlock -

I couldn't find the SSD that Chris mentioned. Would you please point out the exact model?

Jerry Zhong -

I think you could purchase a pcie to M2 adapter and fit a Samsung 950 Pro in there. 960 Pro is coming out soon though with higher performance.

tonynca7 - Reply

I also wanna try the 960 pro on, but I have read an article about the 3rd party SSD support which saying OS X deny to boot from a 3rd party NVME drive, you have to do some hack before you can use it. Is it true?

how i can upgrade mt MacBook pro with retina mid-2015 ?

is Samsung evo 850 fit with my computer

I own a rMBP 15 w/ radeon 15" (w/ the radeon gpu) and pleeassee correct me if I'm wrong but i gotta feeling my SM0512G might be on the brink of failure.I do realize the low probability of such but I'm quite the power user and i've also had some problems with macOS sierra which have led me to "gpt > destroy" the part map 3x.

To be perfectly honest , I'm sh*ttng my pants out scared of running smart mont or whatever 3rd party tool in order to check its current wear levels;

- given that last time i did (couple of months ago - before the whole macOS issues) the wear was at 67%....

There have been no noticeable signs of degraded performance...but sometimes when i boot him up there does seem to be some graphics issues (such as they watch/clock being blacked or greyed or the occasional odd flickering of system issues (they're kinda hard to describe).

not sure what to do. Looking to replace the ssd but the one sold by owc is quite inferior (spec-wise) in comparison to the original.

Any thouhgts/recomendations?

If there are an better after market SSD than the 2 listed please let me know

OK, need a part number (amazon would be great) for a compatible 1T & 512GB for my mid 2015 15" MB Pro...

Is disconnecting the battery necessary just for a HDD change? Or is it here for informational purposes only?

Rob Benton - Reply

Rob Benton - Better be safe that sorry. Always disconnect the battery.

Hi their if I follow the instruction above I will obviosly restart my mac within the Time Machine that I have already made. Is it simple afterwards I just have to follow presidure.??? Tanks for your Help ….Simon

A suggestion for this article, add a step to run a hardware diagnostics check before attempting any replacements. A fresh install of macOS on a new SSD will fail if there are other hardware faults.

Question would the Samsung 860 evo work?

Jason Rose - Reply

Has anyone tried to use an M.2 EVO 860 with 2TB capacity from Samsung yet? Any experiences made so far? Does it work without problems with OS X Sierra? Any comments would be helpful.

Yorh Ekin - Reply

EVO 860 is SATA, it will not work. Macbook pro needs nvme ssd. Just finish my upgrade using ADATA SX8200NP 960GB (ASX8200NP-960GT-C), and adapter is from Amazon, “Sintech NGFF M.2 nVME SSD Adapter Card For Upgrade 2013-2015 MacBook”. Both works like charm. Only issue is that SMART status is unavailable.
