A Note On High Sierra Compatibility with Third Party SSDs

Some users have reported compatibility issues with third party SSDs when attempting to install or run macOS 10.13 High Sierra. In testing, we have identified a related issue with our Aura SSDs. Apple is aware of these issues and we are working with them to resolve this as quickly as possible. Thus far we believe the issue is limited to Aura SSDs  for only these Mac models:

  • MacBook Air (11-inch, Mid 2013)
  • MacBook Air (13-inch, Mid 2013)
  • MacBook Air (11-inch, Early 2014)
  • MacBook Air (13-inch, Early 2014)
  • Mac Pro (Late 2013)

The number of OWC customers affected by this issue is limited, but we take every issue very seriously. We have sent communication to our customers that purchased these specific SSD models, and have been working directly with any customers affected. For those who have not attempted to upgrade yet, we recommend using macOS 10.12.x Sierra or earlier on your OWC Aura SSD.

If you have any questions, comments, or concerns regarding the upgrade to macOS 10.13 High Sierra, feel free to contact our award-winning customer service team.

  • Having problems getting High Sierra to load on a 1 tetrabyte mercury Electra 3G kit I installed in my late 2009 iMac.

    Any thoughts?

    $350 and dead in the water

    HELP PLEASE!!!




  • I have a Macbook Air (13 Inch Early 2015) and I just bought 480 GB OWC Aura Pro Xb SSD. I’m running High Sierra and the drive can’t be found. So expand your list to include the 2015 models




  • Please notify me when this is resolved




  • Leaving a comment so I can get notified on updates relating to this issue.




  • I have a mid 2014 macbook pro with a 512 ssd. I want to install the 2TB ssd. Any issues, problems that you now know about after several months of sales?




  • Please advise when upgrade compatibility to HIGH SIERRA is available.
    thanks




  • I have used a slightly less complicated—at least for me—way to upgrade OWC Aura SSD to High Sierra. The result is an OWC Aura SSD on a APFS volume, that I was able to upgrade yesterday to 10.13.3 without any problems. Here is the process I found on another forum that worked for me:

    – Before starting, make sure you still have the original Apple SSD that your computer came with, as well as any screws that were removed during the OWC Aura SSD installation. If you don’t have them, then these instructions will not work.
    – Use Carbon Copy Cloner (CCC) to make a backup clone of your OWC Aura SSD (OS 10.12.6) startup disk to an external drive. Of course, there are other cloners out there, but CCC offers 30 day free trial, which was incentive enough for me to use it. This step is not necessary, but is certainly recommended in case something goes wrong.
    – Put the original Apple SSD into the Envoy enclosure and connect it to your computer.
    – Use Carbon Copy Cloner (CCC) to make a clone of your OWC Aura SSD startup disk (running OS 10.12.6) to the original Apple SSD. (In my case, I had to temporarily delete my documents, downloads and iTunes library folders, as I had too much data for my 256 GB factory Apple SSD. Once the entire process was completed, I copied these files back from the backup I made in step one.)
    – Shut down.
    – Remove your OWC Aura SSD from your computer and replace it with the original Apple factory SSD from the Envoy enclosure. Make sure to replace not only the SSD, but also any screws which may have been removed during the OWC Aura SSD installation.
    – Restart your machine as you hold down the alt/option key to see the boot disk options. Chose the original factory disk.
    – When the computer finishes booting from the original Apple factory SSD, go to App Store and upgrade to High Sierra. During this upgrade, that SSD will become an APFS volume.
    – Shut down.
    – Remove the original Apple factory SSD from your computer and replace it with the OWC Aura SSD.
    – Put the original Apple SSD back into the Envoy enclosure and connect it to your computer.
    – Restart your machine as you hold down the alt/option key to see the boot disk options. Chose the original factory disk, which is now in the Envoy enclosure.
    – When the machine finishes booting, you can ignore iCloud passwords and Dropbox passwords if they are asked for at this stage.
    – (Although not it was not a part of the original instructions, at this stage I chose to reformat my OWC Aura SSD to APFS Volume.)
    – Open CCC and clone the external Envoy disk (at this point housing the original Apple SSD with OS High Sierra on it) to the internal OWC disk. If CCC asks you to create the Recovery Partition on the OWC drive, say yes and create the Recovery Partition on the new drive.
    – Once the cloning is finished, restart normally. Your computer will boot from the internal OWC drive running OS High Sierra on a APFS Volume.

    I hope this is not too complicated and that it helps someone. If not, it will not be the only useless information on the internet.




  • Hi, I have a Mid 2011 MBA 13″, installed OCW 480 Aura Pro 6G (rev 600 ABBFO) and running OS 10.12.6. When prompted to update to OS 10.13, the process starts but then aborts. I tried several times but no luck so far. Please advice




    • managed to update to 10.13.3 without swapping hard drives. –
      1.) I updated to latest security update on 10.12.6
      2.) made clone with C.C.C
      3.) checked if my firmware on the Aurora needs updating, it did. FOLLOW INSTRUCTIONS CAREFULLY on OCW site.
      4.) after updating firmware for hard drive I tried once more to install HighSierra. This time it worked and files changed to APFS. Had to do the resetting of iCloud account. A note the the hard drive is optimizing did come up. HURRAY it worked. Hope you can do the same by installing the firmware rev 603 ABBFO dated 2015




  • Will a 2015 Macbook Pro with a 1tb drive from Aura ( or another 3rd party manufacturer) be able to run Sierra?




  • I solved this issue with a 4TB Aura SSD on a 2013 Mac Pro but took some hacking to get it to work.

    Backstory: I had it as my system book drive, formatted HFS+ with macOS Sierra in early 2017, and somehow successfully upgraded up to macOS High Sierra 10.13.2 with no issues. Now (early 2018) I decided to convert the drive to APFS by rebooting into the recovery partition and converting it in Disk Utility. It worked, but at the very end displayed an error related to not being able to “bless” the drive as a bootable volume. Upon reboot, the system would not boot into macOS – it just stayed on a black screen.

    The way I ended up solving this was to boot back into recovery, launch Disk Util and unmount the system volume, launch Terminal, and run the “bless –device” command to make it bootable. (Google it to find out the proper syntax). The “bless -mount” command did not seem to be working, but the device command above did.

    (It should be noted that beforehand, I did swap in the original Apple SSD and do a fresh High Sierra install on it to try and coerce whatever ‘firmware’ to install that people in the comments are talking about. I’m not sure if that helped, but I suspect it didn’t have anything to do with fixing my problem.)

    Any way, I hope this helps someone. I spent several hours chasing this issue before I solved it.




  • Dear Team,
    I have a Mac Pro (Late 2013) with 1 TB Aura SSD installed. I am interested, therefore, in any news regarding a resolution of this firmware problem.
    Should I be trying Anthony’s process??
    Viz…MacPro Late 2013 Aura SSD. Now running 10.13.1
    Achieved this by re-installing the original SSD, installing High Sierra, reinstalled Aura SSD and installed High Sierra.




  • I have a Mac Pro (Late 2013), have purchased an Aura SSD and have not received any notifications. At any rate, it is almost 2018 now and no solution yet?




  • I COMPLETED SOME YEARS AGO A MERCURY ELEKTRA 120GB SSD FOR MY MACBOOK PRO EARLY 2011, BUT WITH THE ULTIMATE UPDATE OF HIGH SAW (10.13.2) MY macbook suddenly turns off when disconnecting the battery charger. Any advice about my problem ???




  • Same problem here. I’d really be happy if this problem will be fixed soon




  • I previously left wrong information. Actually, I have an OWC 960 GB SSD. Fortunately, I had time machine backups and could get back to Sierra after High Sierra made my high priced internal SSD unusable. When will this be fixed?




  • I have a new issue. If the Aura SSD can not solve the hardware compatibility, upgrading to macOS 10.13 High Sierra’s APFS can only replace a new SSD. The question is, how to replace the 2tb Aura SSD again, is there a HDD Enclosure compatible? Into a thunder and lightning 2 interface mobile hard disk. Please tell me if any, thank you




    • Dear Sir, on Dec 18th you posted, “Today, my Mac Pro (2013) Aura SSD 2TB is the perfect solution for installing macOS 10.13.2 High Sierra. No need to replace the original APPLE SSD, make the boot disk, right in the Aura 2TB SSD, direct disk formatted APFS format, and then a new installation, everything is going well. The problem seems perfect! At least on my Mac Pro this is the case.”

      My question to you sir, is could you be more specific on making your boot disk, as well as possibly some detailed instructions? Thank you in advance




  • Is this OWC Aura SSD problem with macOS 10.13 High Sierra APFS due to these drives being RAID 0 inside?

    If they are RAID 0, that should have been fully disclosed in the product specifications. Purchasers have the right to know what they are buying. Some manufacturers do not disclose it, and that only fires back to them when it is discovered later on by others. Examples include (undisclosed RAID 0 inside):

    LaCie Bolt3
    SanDisk 900 Extreme

    RAID 0 may be great for some applications, but not for others. For instance, it increases more than twice the failure rate if one of the disks inside or the controller fails. Besides this issue with APFS.




  • I brought a OWC 480GB Mercury Extreme® Pro 6G SSD 2.5″ Serial-ATA 7mm Solid State Drive and when I update to High Sierra start to work really slow and then the computer stop recognize any drive (even if i connect ir via USB)




  • I brought a 1TB Aura SSD for my mothers MacBook Air 2012 model.
    I believe it tried to automatically update her to High Sierra and then failed. I believe this problem extends further then just 2012 models.




  • High Sierra has released an update to 10.13.2。 Excuse me, Aura SSD has a new driver firmware?can be converted to apfs format file system, if not, or to stay at 10.12.6




  • Hello from Austria – I just came upon this place after failing to install HS on my Mac Pro 2013 with a 4TB Aura installed – as apparently everyone else with the same or similar setup. Looking forward to have this issue fixed in the same professional way OWC usually fixes issues…….




    • I used the procedure that Anthony described on my Mac Pro with a 4tb aura and it worked. There are still some intermittent boot and coming out of sleep problems. It did not convert to the new file system.

      Here is Anthony’s process:
      MacPro Late 2013 Aura SSD. Now running 10.13.1
      Achieved this by re-installing the original SSD, installing High Sierra, reinstalled Aura SSD and installed High Sierra. That was it.
      Yes many backups and great care all done very slowly with full erase and installs, but looking back it worked exactly as “documented” which supports the thesis that installing the original SSD allows a firmware update to complete, which then allows everything to run smoothly with the Aura SSD.
      I observe that ANY Apple SSD may suffice, such as one borrowed if the original is no longer available because it is the firmware update that it facilitates that matters, not the rest of the associated OSX install.




      • Are you saying this resulted in APFS on the Aura SSD? That is not supposed to happen, and did not happen when I did the same thing.




        • The process worked for me and have APFS on Mercury Aura Pro 480GB in late 2012/Early 2013 Macbook Pro Retina 15″ (so I can go to Pro X even if I wanted).

          First, cloned latest OS (El Capitan in my case) from MBP to original Apple 256GB Module. Attached via USB in Envoy case.

          Second, installed original Apple 256 module back in MBP and upgraded to High Sierra (was converted to APFS)

          Third, put OWC 480 Aura Pro back in MBP and installed High Sierra again. Worked without a hitch and came up as an APFS drive. I am able to CMD-R to bootable recovery if needed, or Option (boot to alternate drive)..




  • Any word on an update yet? When will this be resolved? Thank you.




  • Same thing happened on my MacBook Air (11-inch, Mid 2012). Two times I ended up with a corrupted hard drive since installing High Sierra. The first time I ended up with the MBA not being able to locate an internal drive (Disk Utility could see both the main drive and recovery partition but could not mount them). Last night, the MBA now gets halfway through the boot up process but then shuts off. Both occurred on the reboot following an OS update restart.




  • I have had two instances of the OWC upgraded SSD in my MacBook Air (11-inch, Mid 2012) becoming corrupted. I had it installed in the last year or two. No problems until I moved to High Sierra. Both problems occurred on the second boot following an update (i.e. not the restart following an update install).




  • On the same boat in regards to this issue and only JUST found this announcement. Hoping for a speedy fix too. This has been a problem for so long now. Some updates and feedback would be nice.

    Thanks OWC.




  • There is a new update (6 December 2017) !! Please, if someone is willing to check whether it works, let us know something!!

    My device: MacPro (Late 2013)
    Thanks!




    • Noper, my $2000 plus OWC again, died like a big dog when I attempted it. If you look at the details of what is fixed there is no mention of any update to SSD. For new people coming in, you get the impression the fix is imminent while in fact there has been nothing done in months and knew about it in beta.




  • My MacPro 2010 Quad Xeon is having major issues with both of my OWC SSD drives – Mercury Pro Extreme 6G 250Gb – the problem happened immediately after upgrading to High Sierra – would be nice if you had emailed in advance – i have 2 of these? please help.




  • May you be so kind to tell me whether will or will not have got a solution for all of us in the following days or the next update, please? I have been waiting for a long time…




  • There is no problem to clean install HS on ANY OWC Aura drive in ANY possible MB Air / Retina config . Formated APFS , of course . Whole process take aprox. 30 minutes to be on clean HS with really simple hack. Tested especially on MB Air mid 2013 too.




    • Does this simple hack also work on a late-2013 MacPro with an OWC Aura SSD? If so, can you tell us more, or link us to a page that explains how to do this? I have managed to upgrade to HS, but not with APFS so far.




  • A friend is selling a Aura SSD 1TB from his Mac Pro 2013. I’m toying with the idea of getting it as I’m still running El Capitan and might upgrade to Sierra at some point, I can then pass on High Sierra for a bit on the off chance somebody has a simple upgrade path in the future.

    BUT, assuming they don’t and this issue persists, can the Aura SSD 1TB For Mac Pro be mounted in an external housing that I can tag along with my Mac Book Pro 13 Retina as an external drive??




    • Steve,
      Yes you can, but the edge slot of the drive is Apple proprietary not standard M.2. Googling external enclosure for Apple SSDs points at a few pages of OWC links. OWC may be the only one that sells compatible external enclosures due to the slot pinout.




  • MacSales,
    It’s been over 2 months since the release of HS, are you any closer to finding the solution? My company IT will soon REQUIRE High Sierra for tool compatibility and security (despite the little root issue recently found).
    I have not received any update since the initial email stating there was an issue. This is not really working directly with affected customers and being disingenuous is not a direction you should be going. I dropped $1600 on your product.
    If the best answer turns out to be that the Aura, HS, and MacPro(6,1) are not 100% compatible (where not having APFS is a showstopper). Then so be it, just state the fact and move on. Of course, the “move on” depends on how well you want to handle the PR firestorm of dissatisfied customers.
    thanks




    • I would add to your comment that the beta to HS was available even few months before the release and the problem was identified well before the release date. So actually it has been 4-5 months. The fact that people posted workaround (with first install on original ssd) indicates that it’s not compatibility issue. It should be just firmware upgrade step before the os installation.




      • I am happy to say that I found a solution for the High Sierra/OWC Aura Drive 480 GB conflict. I called the OWC Tech support after I spent numerous hours with Apple Tech support options, and there is an update fix that the OWC technician walked me through. The install took a considerable amount of time, with some hick-ups and false completion signals, but it eventually completed successfully. Let the technician walk you through it, since there are a couple of tricky instructions, until the install step, and be patient with the process.




  • Please keep me posted on the progress with apple on The Aura Pro X firmware




  • I have an Aura 2 tb installed in late 2013 Mac Pro. I, too, am unable to update to 10.13. Please advise by email when fix is available.




  • Dear Madam or Sir,
    “We have sent communication to our customers that purchased these specific SSD models, and have been working directly with any customers affected”.
    Really ? Not for me !
    Please let me know when I will be able to take advantage of High Sierra on my SSD Aura 1 Tb.
    Thank you.
    Alain Pilorget




  • I have the Mac Pro (late 2013) and have been unable to upgrade to macOs 10.13 High Sierra. What can be done? How long a wait? You have been responsive and great, don’t fail now.




  • Does anyone at OWC monitor or interact on this blog or do you just enable it as a place where customers can share their pain and disatisfaction as your ignore the issue? Having been an OWC customer for many years your lack of engagement with your customers here has really reduced my previously sterling opinion of you as a company. Buck up on this OWC and at least keep us current that you and Apple are working on this with some indication of when next we’ll see an update from you (preferably a solution)!




  • I got no email notice of High Sierra problem. I got many sales promotion emails from OWC Larry. I am staring at a big [?] now, won’t boot.




  • In accordance with owc guidelines, I swapped the OWC Aura SSD from the Mac Pro and replaced the original Apple 512GB SSD, and then successfully installed macOS 10.13 High Sierra, and confirm that the file system has been converted to APFS. I did a backup and then re-installed OWC Aura SSD, the recovery is smooth, but the file system is still HFS +, the file system can not be converted to APFS regardless of the cloning or recovery, and macOS 10.13 High Sierra can only be run under HFS +. I think it is OWC Aura SSD firmware is not compatible, waiting for the new firmware may be very far, I am frustrated, looking forward to improving support as soon as possible




  • Please let me know when there is an official solution for the “High Sierra installation on an Aura SSD” problem. I put a 1 Tb Aura SSD on a mid-2013 MacBook Air about a year ago, and High Sierra installations always fail with a “firmware problem” error message.




  • The aurora SSD I had installed in my 2015 MBP 15 seems to have caused a similar issue. I have gotten “Couldn’t Complete Copy” errors whether trying to upgrade by the app, or installed from USB. Now my system is useless and wont install or power on.




    • Hi Steve, that’s not good, my sympathy. Have you tried “internet recovery”? (alt-cmd-r during startup) I used this alone while doing these (clean install) updates because everything else failed one way or another (MacPro not Macbook) I also first re-installed the original SSD, clean installed HS on that, removed it re-installed Aura and then clean installed HS to that. The theory being that this process updates the firmware somewhere which then allows the Aura update to proceed. Humble apologies if this doesn’t help. Anthony




  • How come there is no solution. I think I will return to you the SSD and buy another one at the Apple Store. My MacBook Air Mid 2012 is not working since I upgraded to High Sierra. I dont have the old SSD. :-(




  • Not sure where my earlier post went to but I did the workaround and it worked BUT now the 10.13.1 update is not installing which I’m sure is related to this. Be sure to do a back up before updating to High Sierra!




    • MacPro Late 2013 Aura SSD. Now running 10.13.1
      Achieved this by re-installing the original SSD, installing High Sierra, reinstalled Aura SSD and installed High Sierra. That was it.
      Yes many backups and great care all done very slowly with full erase and installs, but looking back it worked exactly as “documented” which supports the thesis that installing the original SSD allows a firmware update to complete, which then allows everything to run smoothly with the Aura SSD.
      I observe that ANY Apple SSD may suffice, such as one borrowed if the original is no longer available because it is the firmware update that it facilitates that matters, not the rest of the associated OSX install.




  • Although I don’t appreciate the time it has taken to not get an update to this issue I did do the workaround listed by other users and it worked flawlessly. Took 2 hours from start to finish but shouldn’t have to come to this.




  • Same problem here. OWC Aura SSD 500GB
    MacBook Air (13-inch, Mid 2013) running 10.12.6 cannot get past the firmware error when trying to upgrade to High Sierra.
    Any news on a fix?




    • I don’t have time to deal with workarounds that might or might not work. I’ll stick with Sierra until there is a resolution. My problem is the lack of transparency. C’mon OWC, give us a real update. Whose problem is this to fix, yours or Apple’s? Where are you in the process of fixing it? What is an estimated date you will have this resolved? Is there any possibility it can’t be fixed? Please be responsible and give us some real information. Thanks!




    • I gave up waiting for a fix. Even contacted support, and have not heard back.

      Using original SDD method worked for me.

      I have Air, 11″, model 6,1 (late 13 or early 14). I put the original SSD in, did an internet recovery, and installed high sierra. Took original SSD out and put OWC Aura 500GB in, and updated to high sierra and it worked without any trouble. Did a backup before just to be careful.




  • The Work Around Process, worked great for me.
    OWC Aura 4TB installled. re-install apple 1TB,
    cmd+R, ran Disk utility (Erase), installed High Sierra.
    Shutdown, re-install OWC Aura 4TB, cmd+R, ran Disk utility Re-install OS High Sierra, when it restarted, it was still running Sierra, went to app store open/loaded High Sierra and ran install again, that was it. Did not need to rebuild from Time Machine, everything was there and working great, just like it was, running High sierra (10.13.1). Man that is a load -off me.




  • It’s working now. If you try to install it will launch a firmware update. Once you do that… it allowed me to finally install High Sierra on my tower Aura SSD drive.




  • I have a 2013 Late Mac Pro (6 Core) with OWC Aura 4TB installled.

    I got tired of waiting for an official fix. So I just went with the confirmed workaround: swapping OWC Aura SSD with the origial Apple SSD back and forth.

    I can also confirm the workaround REALLY works. I had misgivings since so many complained about their Mac Pro getting bricked and all.

    Yeah, the nightmare became reality when my Mac Pro seemd to have gone nuts with its fan shrieking.

    But I realized that I forgot to put back those power screws (not sure what they call them, those screws that connect Aura’s power cables to Mac Pro’s board.) Those are easily forgotten if you hurry. When I put them back on, everything went ok. It was logical: it should just work since it’s like not having installed the OWC SSD in the first place. No boot with shrieking fan? Check your screws.

    Well, if you have sold your original Apple SSD, you might be out of luck.

    But if you do have the Apple SSD, at least you have a choice: wait for an offical fix that might never come or just invest a couple of hourse of elbow grease.




    • One thing you should also consider is if you have any bootable external drives or RAIDs, if you have them with any OSX version other than High Sierra on those drives, those external drives will not be able to read files on your High Sierra drives. For this reason, I opted to keep El Capitan for now. Has anyone experience with installing High Sierra on HDD drives?




  • I have a MacBook Pro 17″ (Late 2011) – MacBookPro8,3. I installed an OWC Mercury Electra 3G MAX SSD 1TB hard drive back in 2014. I tried the macOS High Sierra update several times by myself and with the assistance of several Apple Specialists over chat and on the phone. Eventually that had to do call me back so that they can have some of their engineers look into my particular issue. One issue was the EFI firmware not updating, or something like that. When I would boot into CMD+R or CMD+OPT+R, it would want to install OS X Lion. Eventually I was able to update this portion of the EFI and now when I boot to Recovery I can install macOS Sierra, however, I attempted an upgrade again to macOS High Sierra and it gave me the same firmware verification error. The latest Apple Specialist has set up an appointment to a local Apple Store so they can try something out. Total number of hours spent trying to get macOS High Sierra… 10 hours. Good luck to the rest of you trying to figure this out.
