Hi I purchased a Samsung ssd 870 evo hard drive, and I am trying to install this. But the connection is not the same as the old hard drive. How can I get this installed? Is there a new cable that I can buy or some other trick? Glad if you could help me Eric
Sadly, Eric Apple did their own thing with their blade SSD’s. The Samsung 970 EVO SSD is a M.2 SSD and is not designed to work in your system without an adapter (if it supports PCIe/NVMe drives which this system doesn’t). This MacBook Pro is an mSATA based system as you can see in this great guide The Ultimate Guide to Apple’s Proprietary SSDs so this SSD won’t work as it’s a PCIe/NVMe drive. You will need this SSD OWC Aura Pro 6G SSD and follow this guide MacBook Pro 13" Retina Display Late 2012 SSD Replacement
870 EVO is designed as an 2.5 inch spinning drive replacement SSD, the case physically will not fit in a Retina MacBook Pro. Even if you take out the case and put in the naked board directly, getting an adapter will be extremely tricky. Most adapters are designed the other way around, converting Apple SATA SSD into generic SATA, opposite of what you want. At this point it is easier to just buy a correct SSD.
