OWC’s Aura SSDs Not Working With macOS High Sierra, Fix Coming Soon

Mac owners who have replaced their machine’s storage with Aura SSDs from OWC are not able to install macOS High Sierra at this time due to an incompatibility issue that prevents the update from successfully converting the drives to the new APFS format.

The Aura SSDs show up as “Rotational” drives instead of Solid State, and when attempting to install macOS High Sierra, users are seeing an error message about a firmware update before the installation process crashes.

Several customers who have purchased Aura SSDs have complained on a macOS High Sierra beta blog post, as the issue long pre-dates the macOS High Sierra release. One customer was told that new firmware would not be developed until the High Sierra golden master was released, but new firmware has apparently not made it out yet.

OWC offers Aura SSDs for a range of Macs, including many MacBook Air, MacBook Pro, and Mac Pro models.

According to customers, OWC is recommending users re-install the original SSD that shipped with their Macs, download and install macOS High Sierra, and then swap the Aura SSD back in. OWC is working with Apple on a fix for the issue.
