How do I update firmware so new hard drive will work?

I am replacing the hard drive in my macbook air because the old one failed. I have installed the new drive but OS X Utilities can't see the new drive because I think the firmware needs to be updated. An instruction in the new hard drive package says:

"Mac OS 10.13 High Sierra (or later macOS) must be installed on the host computer before installing the Aura Pro X SSD. These versions included an EFI firmware update for your host computer. Without this update, your new Aura X Pro will not cunction once installed."

How do I update this so the computer can see the new drive? The old drive did not work so I am not sure how that would be an option.

Answer this question I have this problem too

Is this a good question?

How about leveraging Internet recovery! Then you can install the older OS onto the drive first so you can then update the firmware Or download the OS installer and then install the older OS onto a USB thumb drive to then run the firmware updater and Disk Utility to prep the drive.

Keep in mind High Sierra will upgrade the GUID Journaled file system to the newer GUID APFS. If you don’t want that you’ll need to install Sierra and stay with it. Or edit the OS installer script How to Skip Converting to APFS When Installing macOS High Sierra

I thought this would be a possibility, and I started the computer in recovery mode, but it seems the computer cannot see the new drive without the firmware update in place. I think the bootable external drive is going to be the way to go.

I have the exact same issue. The computer cannot see the new drive without the firmware update in place.

Did the external drive method work?
