In later iterations of MacOS 10 and MacOS 11, Apple’s install would not always update the firmware of systems using 3rd party NVMe storage—even if the operating system itself was installed properly. Unlike macOS 11 (“Big Sur”) which required no firmware update, Monterey will not successfully install on a machine with an OWC SSD installed if the firmware is older than the fall-2019 macOS 10.15.x Catalina iteration. This impact will be noticed when attempting to install or update an OWC Aura N2 or OWC Aura Pro X2 SSD.
Any users who might be encountering this issue should update their system firmware to the latest (4xx.0.0.0.0) before attempting to install macOS 12.x on their OWC Aura N2 or OWC Aura Pro X2 SSD. We recommend confirming the current firmware version under System Report. The host firmware version can be confirmed under System Report –> Hardware Overview –> System Firmware Version.
Some of you might have received this error message:
Error Message: A required firmware update could not be installed. Compatible internal storage is required in order to update
The only way to address the above error is to re-install an Apple factory SSD and perform an install of the latest OS available for your Mac.
If the host system firmware has been updated to the fall-2019 release or later, macOS 12.x will install and the System firmware will update with an OWC SSD installed.
This firmware issue occurs regardless of install method:
- OS updates via system preferences
- Internet recovery install
- Bootable install media
Please contact our Technical Support Team if you encounter issues installing or upgrading to macOS 12.x with an OWC Aura N2 or OWC Aura Pro X2 SSD.
