I have a 1TB OWC Aura Pro X2 SSD on my MacBook Pro (Retina, 15-inch, Mid 2015) model. I'm currently running macOS BigSur 11.6.1, When I tried to upgrade to macOS Monterey the update fails with a generic message saying "An Error Occurred While Preparing the Installation ...", In the logs I could find errors highlighting that the EFI drivers are outdated. I checked the OWC website and I could not find any firmware update matching the current macOS that I have, Any pointers on how to solve it ?

here it is

Search around there was more info on these forums—

been some insight ... as to a way forward

reinstall the OEM Apple drive—then update the macOS to get the firmware/EFI into the machine, then reinstall your OWC Aura and carry on with upgrading the macOS on that drive.

ask OWC.

They pride themselves on their support, and they made money selling you that drive.
