Here's a dumb question for the moderators - if I run the above command with RC Scripts and EmuVariableUefi present, it should return the same result right? Meaning, this test is ONLY valid if you currently DO NOT have RC scripts or EmuVariableUefi installed? If both are present, the above test is useless?

Here is a blast from the past. Just updated my Asus Z170 Deluxe BIOS to 3007 from 1801 and there is no longer native NVRAM.
Tested the TestVar=HelloWorld and it returned nothing. I only noticed since macOS is defaulting to OS X drivers.

Hi thanks for your information, if that's true, i think they have changed some hidden BIOS options to make nvram unaccessible to macOS. I have decoded the setup section of your motherboard BIOS, 1801 and 3007, those are all the settings, maybe someone could help to find the differences and show some tips of enabling nvram for any motherboard/chipset?

attached are the setup section of v1801 and v 3007

Dell XPS 8700 supports NVRAM.
Follow down the screenshots from tests.

Require Emulated NVRAM by installing RC scripts and EmuVariableUefi-64.efi
Looks like my Gigabyte 250M motherboard supports native NVRAM.

I've remove EmuVariableUefi-64.efi driver, shutdown, start, set a variable, rebooted. I found the variable there. I think this mean I'm using native NVRAM, right?
