A solution of ASUS new bios ver.2012 (not downgrading)

Sorry for my bad English. It's not my native language.

I'm using ASUS ROG Strix B360-i Gaming motherboard with Samsung PM961 Nvme SSD.
After I update the BIOS to version 2012, I have also ran into the problem that my hackintosh never boot again.
It just stucks at the progress bar with Apple logo.
And I noticed that the boot log stopped rolling when "SMCRTC:start" appears.
(The "AppleNVME Assert failed" error is misleading. But it's not the cause of this problem.)

Then I found an bios option about RTC was added with this bios update.
It's located at UEFI Advance Mode\Advanced\PCH Configuration\System Time and Alarm Source:

I changed the option from "ACPI Time and Alarm Device" to "Legacy RTC".
And my hackintosh is working now.

I hope it's a useful solution for this problem.

THANK YOU!!! Confirmed! Working for my ASUS PRIME B360M-A as well. You are a gentleman and a scholar etc etc.

I've combed through BIOS settings for weeks and never thought it could be due to something as simple as "System Time And Alarm Source."

Many users completely replaced their motherboards, I'm glad I was patient.

Thank you.
Will check in the eve with my ROG STRIX H370-I and will let you know.

Obviously an issue that all owners of current ASUS boards should have in mind if their boards have BIOS updates available. Nice finding!

Thanks a lot, you saved my day !!! Asus prime H310m-a worked after apply this solution

Thank you very much. U made my day.

Got the same board. Did you find an alternate solution? I can't rollback the bios. Maybe there is something else I can change?
