Go into 'About This Mac' then select 'System Report' Please take a screen shot of the 'Storage' window, then take a shot of NVMExpress window (you may need to slide the slide up a bit to get all of the info).

You're seeing the default setup of the drive. Its been awhile since I've put one in if I remember correctly you need to erase and re-prep the drive.

Restart your system and go into Internet recovery (left Command, Option & R keys), or you can boot up under an external USB drive. Press the Option key to get to into Boot Manager.

Then once booted, go to Utilities, Terminal, within Terminal type the following:

diskutil unmountdisk disk0

gpt destroy /dev/disk0

Close Terminal. Open Disk Utility select the Aura drive on the left pane and erase it and reformat the disk, re-install the OS again and migrate your stuff back over. That should do it.

Thanks! Somehow auto correct messed it up.



This is Steven. If this still does not work, what else can I do?

Hey Steve,

I've done this process and didn’t work for me. So, I continue to search for more answers and guess what... heheh...

The manufacture provides some software which seems to be like a driver for the SSD. After installing this software, the mac reboot. And now it’s recognized as internal SSD PCIe Drive. :)

OWC Dual Boot Enabler

Because, the most part of users (includes me) are having problems to use BootCamp on this SSD. As BootCamp cannot be installed on external drives.

So.... thats it. I hope this can help you.
