Instal BIOS update from Mojave with out installing Mojave?

[nudoru]

Is it possible to (easily) install the updated 5,1 bios from the 14.1 Mojave package with out installing Mojave? I don't have a metal capable card yet (one on order) - but I have a little spare time today.

I bought installed a NVMe before realizing you needed the updated BIOS to boot from it. ¯\_(シ)_/¯ I'll RTFM next time.

The native Apple Firmware updater won't run without Metal card.

Buy Metal card from Amazon(you have Prime, right?), do update, return card. Kind of a D move, but if you're low on cash, it's an option.

You can do the 140.0.0.0 update and quit the installer, staying in High Sierra with the new NVMe boot firmware.

Thanks both!

I'll wait till my metal card arrives and do it then.
