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.



  • Been dealing with his issue for 2-3 years now on an Aura 4TB Mac Pro SSD. Spent countless hours – no, days – troubleshooting and googling. Unbelievable something that cost that much has caused this many headaches with no actual solution or firmware update from OWC. A few days ago I had to jump through hoops – once again – because Mojave would refuse to install. Had to pull the Aura, swap in the Apple SSD, install Mojave, clone the install to a USB stick, swap in the Aura again, format it APFS, clone the USB stick to the Aura, and cross my fingers that it would boot. Thankfully it worked. This, after literally 10 years of buying different generations of SATA SSDs from OWC for different machines, most of which failed within a few years. I’m so absolutely fed up and done with OWC it’s not even funny.

  • What a nightmare I have had with 480GB OWC Aura Pro Xb SSD. Both in High Sierra and Mojave on a mid-2013 Macbook Air !!! Kernel panics constantly, eventually disk file corruption when it is actually able to boot up. And what is up with the huge chunk of thermal putty attached to it when the original Apple SSD doesn’t need that? What a disaster. I had to send it back. Now using the original Apple SSD and it runs much cooler and back to rock-solid reliability. very sad.

  • I replace my 2015 MacBook Pro hard drive with the OWC 1TB Drive. I get a File and ?. I tried numerous fixes and nothing worked. I reinstalled the old drive, upgraded to the latest software and Mojave. Reinstalled the drive, same thing. I’m so beyond frustrated. I have followed every possible way to fix this problem. I spent most of the day on it reading every possible solution. I’m ready to use it as a frisbee for my dog.

  • I have a 2013 Mac Pro cylinder 6,1 with the OWC 2TB SSD as the internal drive and am unable to upgrade to High Sierra. I have done a firmware update but still am unable to update the Mac Pro.

  • Hi.
    I have a Mac Pro late 2013 running Mojave10.14.1, just purchased the 1TB Auro Pro X drive. System does not recognize the drive and to make matters worse as long as the drive is installed the system refuses to boot into recovery mode.

    So far not heard much back from OWC.

  • I had followed the process to update the firmware when high sierra was released for my Mac Pro 2013 with the Aura 4 TB SSD. The firmware is installed through a Marvell software RAID manager. I was able to get the Mac Pro to update and run properly but maintained in in HFS+ as I was unable to format the drives as APFS and I was concerned about APFS being stable enough for my configuration. Yesterday I just updated to Mohave and voila…it updated without a hitch and now my boot drive is now APFS with an indicator that its “shared by 4 volumes” in Disk Utility. So far so good…fingers crossed it stays stable.

  • Aura SSD Firmware Update:

    Jarrod Rice Thank you for your help.
    followed your steps and it worked with no problem (Late 2013 Mac Pro Aura SSD 4TB).
    I am now running 10.14 with APFS Volume on my Aura SSD 4TB.
    Again Thanks. William

  • Would love a fix for this too, as 10.14 (Mojave) is now the current OS.

  • I have this problem. Funny that OS X refuses to install, but didn’t refuse to upgrade to High Sierra. I ended up with an un-fixable file system error. Trying the approach of installing previous OS

  • Would love to be notified when this firmware update is finished with Beta.

  • OWC released a firmware update (still beta) for some Aura SSDs back in February.

    After the Installation i was able to install latest Mojave beta on my 1 TB Aura SSD

  • I’m a developer here as well. What can I do to fix this issue? It is especially annoying because I’m running high Sierra already and I’m trying to update to mojave. Does anyone have a solution?

  • Trying to install the Mojave developer beta on my MacBook Pro with a 1Tb OWC Aura SSD.
    Even though I am attempting the Mojave install, I am getting the message:
    MacOD High Sierra cannot be installed because the third-party storage installed in your Mac is not compatible. Please contact the supplier directly for assistance.

  • I have a 13 inch MacBook Pro with the 1G Aura SSD installed. I tried to wipe it and put a fresh install of High Sierra 10.13.3. No Joy. Got a message that my SSD was incompatible. Fortunately I had a backup, but it took 18 hours to restore from a USB 3 drive.

  • I have a Macbook Pro 15 Retina and the only way the drive worked was to install a fresh copy of High Sierra from USB and then migrate the data from the apple drive or time machine.

  • I just installed OWC aura pro ssd to my MacBook Pro 2013, however it seems to reboot two times by itself everytime I turn it on. I don’t know if this cause by the ssd or if it just the way it is! Also the SSD has been causing my MacBook Pro to over heat which forces the fans to run 80 percent of the time.

    Do you think you guy have any solution of that?

  • Once again issue related to the compability. In my case, the screen displayed the following quote: “macOS Sierra cannot be installed because the third-party storage installed in your Mac is not compatible. Please contact the supplier directly for assistance”… so I do.

    By the way, I had already had some issues in the past which I had resolved by installing the original one into the MacPro (2013)…. however and very saddly, the problem seems to arise once again

  • I purchased a ssd for 13″ MacBook Pro Retina display (2013) back in Nov/Dec. It has been working fine until today. When I attempt to reinstall IOS over the web, I get an error message that says my hard drive is not compatible? I had just upgraded to the newest version of High Sierra.

  • Just a note for everyone here, I was having trouble with installing 10.13. When I re-installed the original SSD (including the screws), I got a black screen and the fans spun up. I was still under applecare, so I took it in and they replaced the logic board, I/O board, and I/O flex cable. These mac pros have a high failure rate, so if you are having problems, and have the original SSD and applecare, it might be worth it to have apple check it out.
