I bought a 480GB OWC Aura SSD with a known compatibility issue for my Macbook Pro 15" (mid-2015) after my old SSD died. I installed the drive and partitioned it. It shows up when running
diskutil list in a High Sierra recovery terminal, but not on any older OS versions (Yosemite or El Capitan)
The High Sierra installer lets me choose the new SSD as a target destination, but after the first reboot the machine goes to the "question mark folder". Apparently, I need to upgrade the firmware on the OWC Aura Pro SSD, but I'm having a hard time getting the PHP updater to work.
Should I request a refund/replacement or is there a way to make bootable USB to update the drive's firmware?
Edit: I managed to boot into High Sierra from an external and ran the Marvell firmware updater, but it does not detect any drives under the "Device" list for me to update.
