I recently wanted to upgrade the 128GB storage in my late 2012 retina Macbook Pro (A1425). I got an mSATA to 7+17 pin connector adapter and a 480GB Kingston UV500 (SUV500MS/480G) but my Mac refuses to work with it. Sometimes it can see the drive in disk utilities, sometimes not. If it does appear I'm not able to properly erase or partition the drive.
If I boot into macOS using a USB-stick and look in the system information I can see under SATA that the machine detects that something is there since it successfully negotiates a 6Gb/sec link, but it simply says "Unknown" instead of any drive information.

I know that the adapter works, I have tested it with another 24GB mSATA drive I had lying around without issues. I also know the Kingston drive is OK; i placed it in a regular mSATA -> SATA adapter and it works perfectly fine in another computer.

So my question is if anyone else has any experience with this combination of MBP and SSD, successful or not? I haven't been able to google any concrete information, except that some seem to have an aversion to Marvell controllers since they don't always play nice in Macs, but as far as I could tell that was mostly an issue for older Nvidia chipsets?

Did you succeed in the end? I'm trying to upgrade an A1425 MBP10,2 (13") with a 1TB Samsung 980. I got hold of a cheap adapter, but the MBP neither recognizes the Samsung nor a Crucial P1. Any hints, which adapter would work?

In your case, you have the wrong drive technology. The earliest round of Retina Macbook Pros used a SATA drive with a custom controller. You're trying to install a PCIe drive. It cannot be done. To upgrade a 2012-2013 retina Macbook Pro, you need an mSATA drive on an appropriate adapter.

Thanks for your answer. Yes, I was pointed to this yesterday:


The post contains information about the MBP 2012/13.
