Chosen Solution
Upgraded my Mac Beginning this year with an OWC Aura 480GB drive, now I cannot upgrade to high sierra for OWC drives to not support the filesystem change. So invested 450€ and now got stuck. Manufacturer does not help at all. Offers a new line of drives costing the same. So another half thousand bucks??? Does please anybody have an idea what I could do? Thanks very much in advance
The problem is both OWC’s & Apples! From The SSD Review “The OWC Aura contains two SMI 2246 XT 4-channel controllers which are situated in a RAID configuration through a Marvell 9230 RAID controller. There are four unbranded 256MB MLC synchronous NAND flash chips which, once paired, create a RAID 0 volume with a 1TB capacity.” Basically, they tried to maximize the performance on what chips they where using. I personally think this is more an Apple mess up than OWC’s. OWC could have posted something to at least acknowledge the issue or contacted you if you gave them your email address. All we got was a MacRumors posting with no follow up. Or, info on where to look for news. The Apple piece is the current release of APFS does not support RAID drives! So what to do?? Sorry to say you’ll need to wait a bit more until Apple fixes APFS to support RAID on the boot drive and if needed OWC to update their onboard firmware and/or device driver.
You need the Aura Pro Xb. It is compatible with High Sierra.
