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.

I'm responding to this post late, and my contribution is a workaround for Aura SSD install/upgrade to High Sierra on a Power Mac, late 2013.
