Adapter SSD for MacBook Pro 2015 a1502 works?

Hello, I've researched in several places and nothing seems correct

need to expand my current mac from 128GB to 512GB but are very expensive

I found an adapter that converts ssd (mac) to ssd common

what adapter do I need to buy to run this type of ssd on my mac?

I really don't recommend using these adapters. When we tested them a year ago we found they had a heavy CRC error count. Getting the correct SSD for you system is the smarter direction.

Here's a good write up on the different Apple SSD's The Ultimate Guide to Apple’s Proprietary SSDs

Here's IFIXIT's offering: MacBook Air 11" (2013-2015) 13" (2013-2017) MacBook Pro Retina 13" and 15" (2015) SSD

@danj - can you provide reference material regarding your comments on CRC error count? How significantly did these errors affect performance? Did you A/B Gen 5. Apple SSD to third-party NVMe SSD with adapters?

I'm investigating the benefits of upgrading my mid-2015 15" MBP Retina SSD to one that supports NVMe.

Options for purchasing a salvaged Apple SSD are considerably more expensive than purchasing a Samsung SSD with adapter...

I have seen youtube videos showing successful upgrades to third-party SSDs. I did not see any comments on CRC errors, though.

I would love to hear your opinion/comments on this subject. Thanks!


Update (06/20/2018)

Pt. 1

@mayer I would follow your recommendation, but the purchase cost is non-negligible.

Thanks for the information @danj. Yeah, I'd prefer to get a salvaged Apple SSD, but they're considerably more expensive.

I produce music with my MBP, and I'm currently experiencing overheating issues and the subsequent unraveling of Ableton Live at high sample rates and multi-track recording. I'm building a Hackintosh in the mean time, but I am curious to see if my MBP heat problem can be reduced.

For multitrack recording, reading/writing audio streams to an SSD is the main work-intensive task. This is the incentive for me to pursue this option to begin with.

Pt. 2

OWC sells Aura Pro X drives that do not require an adapter, but the user reviews on Amazon are split about 50-50 positive negative, with issues relating to increased heat & OS malfunctions post-install.

It also looks like Apple purposely attempts to ignore third-party drives.. Installing such an SSD may not be a future-proof option if Apple is actively fighting the third-party SSD community.

Going this route may be an exercise in frustration, a la "fixed one problem and made another.."

Pt. 3

The Beetstech HD site has this quote which I'm going off of for pursuing a new SSD option.

"Both the 13″ and 15″ MacBook Pros also support the NVMe protocol and upgrading to Gen. 5 SSDs can bring a modest speed boost to the 13″ model A1502, but the 15″ model A1398 with its PCIe 3.0 connection really allows the NVMe technology to shine. Read speeds increase by ~40% and write speeds can increase by ~60%."

I will message the author and see if he can shed some more light on options for better performance..

Thanks for your comments, guys!

I think you should just ignore the links and advice that Dan gave, Go ahead and do it your way then come back and tell us what the major and minor problems were.


We did the testing over a year ago and we built custom scripts to test things. I don't have access to the raw data any more. I can tell you without a doubt the quality of the adapters we had tried were quite bad. These were mSATA M.2 drives which we had used as at the time there was no PCIe/NVMe support in MacOS for these newer 3rd party PCIe/NVMe drives. Even after our testing I had tried a M.2 PCIe/NVMe drive for someone and was never was able to get it to work.

Keep in mind CRC errors are hidden! They are within the driver we needed to do some deep diving into the code to get to the error handler.

So what hard is there in excessive CRC errors? Think of it like you're telling someone who is hard in hearing and they keep saying: "what did you say?" This gets into who is sending the data!

If the drive is sending to the system then the system will tell the drive to resend the given block no harm to the drive but your system will need to handle the repeating task which can slow down the system as well as cause the drive & CPU to heat up.

Now lets turn this around where the system is telling the drive to write something.

Here the mis-write of the data (incomplete) will cause the drive to use a different block so over time you'll wear the drive down (shorting its life). It also will cause the drive & CPU to heat up. Now this doesn't sound like such a big deal but these CRC errors are not one or two but a string of 1000's when you are stressing the system.

The risk here is the integrity of the data if your dependent on it not being corrupted then using these adapters puts you at risk.

As for PCIe/NVMe drives this is even harder! As unlike the SATA protocol which has checks NVMe is much lighter a dialog and has less cross-checking!

Bottomline stick with what the system was designed with!


Apple were using 4K sector size SSDs, Toshiba/OCZ could be converted to that using a utility and those worked fine but Samsung and all the other brands were stuck on 512 and thus didn't work which is probably what happened to you. Apple added 512 support in High Sierra, whilst newer Samsung SSDs became 4k so the problem essentially resolved itself.


@malhal - What?? mSATA and AHCI are very different animals to NVMe!

Even still your incorrect as far as the NVMe block sizes.

The newer black Sintech adaptor sold on Amazon seemed to be working very well with a number of users on the Macrumors thread at Upgrading 2013/2014 Macbook Pro SSD to M.2 NVMe

The thread title is misleading. A lot of users are using Samsung NVMe M.2 drives with 2015 Macs without issues.

2013-2014 Macs would require a modded EFI firmware or some workaround to work reliably.

I have exactly the same requirement.

I have not bought one yet but most of the Posts that I have seen recommend the Sintech. This is reported to work with MacOS, Windows and Unix but you must install a later version of MacOS before plugging it in or it will not be recognised. It is also recommended buying this adapter direct from Sintech in China as there may be fakes that do not work?
