Introduction

Use this guide to upgrade or replace the solid-state drive in a MacBook Pro 15” Mid 2015. 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.

So guys, I got a couple of questions:

1. Is this model (MBP Retina Mid 2015/MacBookPro11,4 ) really upgradable? https://www.datenreise.de/en/macbook-pro... 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.

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.

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?
