[Success] ASUS Prime Z370-A+i9-9900k Pro Audio Build

[NorthAmTransAm]

@NorthAmTransAm,

Thanks for your amazing work!

I attempted to update from Mojave, which was working perfectly, to Catalina. Everything works (though it seems very sluggish) except for audio, the only option being HDMI, not the optical port which I do need. I grabbed the EFI you created for cnsilvan since I have a rev 1 board. What am I missing?

BIOS is up to date. Based on another post I read, I wiped the EFI > clover folder from my Mojave install as I was running a 4xxx version of Clover, so essentially starting from scratch.

I don't have the Thunderbolt card as I use Dante Virtual Sound Card for getting audio in/out, but I imagine having the kexts installed won't hurt?

I updated posted 1 and attached a current OC 065 EFI. Make sure to add your serial!

Did you follow the Dortania guide for creating an installer?

Did you add your own serial number and place the EFI on the EFI partition?

Your board is a little bit different so it might require more reading. Check everything!

Guide updated with OC 065 and Clover EFI for macOS Big Sur.

The Clover EFI has SATA Unsupported instead of the CatalinaAHCI kext. Either one should do on this board.

Please add your own serial and look at the USB chart to see if you need move your headers around or edit the USBmap. Dealers choice.

1. Yes I did
2. Yup I did changed "MAKE YOUR OWN" and also change systemUUID
3. My board is asus z370-prime-ii. (i guess this part involve more in kernal panic but not the booter)

I took a look on your efi folder and found down that, you're using BoxHFS.efi instead hfsPush.efi like Dortinia guide i also replace two of that but still opencore booter couldn't detect the installer partitions. i mean it have reset mvram and everything but no installer.

So you are getting to the Opencore menu, but you're not seeing the installer you've created? Is this correct?

If so, please go back to the original EFI from the guide and make sure you've changed your graphics platform ID to the correct one for your setup. Also make sure you re-add your serial and whatever is missing!

Then head over to your config and change Misc>Security>Scan Policy to 0.

Report back.

Hey NorthAmTransAm,

Back at it after a slight delay. Thanks for creating a Clover EFI in the meantime, I get that OpenCore is the future, but it took me too long to have just a basic understanding of Clover!! Is the new EFI only good for Big Sur or will it work with Catalina too?

I tried running it last night on Catalina (after adding my serial number) and could not get it to boot. Boot screen photo attached. What am I doing wrong??

With Mojave, the SMBIOS was set to 18,3 but stuck with 91,1 from your build.

As a refresher, I've got the same cpu, GPU, and a first gen Z370-A Prime with 32GB of RAM in slots A2 and B2. Can't use slots A1 and B1 as it won't fit under the CPU fan, which I remember being an issue in the past, but can't recall the workaround....

Thanks again for all your amazing work!

Interesting. I’m going to give it a test on a Mojave backup when I get home in a couple hours.

In the meantime, try disabling whatevergreen in the Config and also disabling the CatalinaAHCI kext. Let me know!

Sorry it I wasn't clear, running Catalina, not Mojave. Will try both and report back
