Hello,is there a methode for booting with this problem? i didnt have that option

 

[SteelEloy]

Hello. I wrote in the technical support asus. They told me that the Legacy RTC is Legacy CSM or Launch CSM is in the boot. Is it true or not?

Asus Z390-A Prime Bios 1105.

The problem is like the others: https://www.tonymacx86.com/threads/fix-for-boot-hangs-after-bios-update-acpi-patch.275091/page-16

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.

Tons of Thanks ....You Saved my Thousands of Hours Man

I do not have any RTC settings in my BIOS. Any suggestions?
Using Asus TUF Z390M-PRO Gaming. Updated BIOS to 2417 this morning and now have this same problem with macOS not booting.

FIX for boot hangs after BIOS update (ACPI PATCH)

This is an ACPI Patch for the people who update to the last bios and can't boot. My board is the MSI B360A-Pro and has the latest bios 7B22v27. First add the patch (the blue line from the picture) to clover config, then apply the Bios update. To easily add the patch using terminal, read post #48
