This article describes the process for applying a firmware update to the Aura SSD. The update improves compatibility for: 

  • macOS 10.13 
    • Due to an error caused by the Aura SSD's controller, previously, we required the 10.13 upgrade be installed via the Apple SSD as a first step. This firmware update removes that requirement and ensures your Mac will receive the appropriate EFI update as part of the system installation.
  • Hibernation 
  • Cold booting
