[Success] - Asus ROG Strix Z490-E Gaming + i9 10900K + OpenCore

It sounds like your USB drive maybe incorrectly configured, you can check in the bios if it shows as a boot option or by hitting the F8 key at boot. Make sure when creating the pen drive to format it correctly, I use the terminal command "Create Media" which you can google and then copy and paste into the terminal window. Once that part of the drive is done mount the EFI partition (I use EFI-Agent from Headkaze available on GitHub) then add the EFI folder there. Lots of ways to do the same thing so just a suggestion. @scope666 may have more suggestions...

I'm sorry, i expressed myself badly. I meant that opencore does not detect BigSur .dmg, the pen starts up without problems and the bios is set correctly.

Making further attempts if i put my EFI folder in the pen, OpeCore detects the Big Sur .dmg file.

Okay, thanks for clarifying. So are you okay now? You can see the Big Sur install icon now?

Hi there,
please check your ScanPolicy value (usually is 0) and check MinDate and MinVersion in config.plist/UEFI/APFS. Starting from OpenCore 0.7.2, if you're not running Big Sur you can't detect previous macOS APFS disks. The only way to do it is chaning the MinDate and MinVersion values to the following:

Please note that the following values are extracted from OpenCorePkg/OcApfsLib.h

macOS Version	MinDate	MinVersion
High Sierra 10.13.6 (17G66)	20180621U	748077008000000ULL
Mojave 10.14.6 (18G103)	20190820U	945275007000000ULL
Catalina 10.15.4 (19E287)	20200306U	1412101001000000ULL
Big Sur 11.4 (20F71)	20210508U	1677120009000000ULL

If you wanna OpenCore detect every APFS partition, without any exception, set both values to -1

P.S. About the graphics patch, since you're using a headless AAPL,ig-platform-id you can drop pretty every property. Just make sure you leave AAPL,ig-platform-id, igfxfw and model properties

Thank you very much, the problem was their MinDate and MinVersion values set to 0. I set them both to -1. Now i have started the installation i hope there are no other problems. I keep you updated. Thanks again.

You figure if he is using @scope666 EFI folder that's not an issue but thanks for jumping in

EDIT: Well there you go...it was the changing the MinDate and MinVersion values

I can change this in the EFI so going forward people don't have this issue during install.

EDIT: Attached

UPDATE:

OpenCore with values -1 now detects Catalina's .dmg file but not BigSur's. I only have Windows.

I try to put the dedicated values for BigSur as suggested by dreamwhite:

macOS Version MinDate MinVersion
Big Sur 11.4 (20F71) 20210508U 1677120009000000ULL

In the guide they're only saying to change it if you're trying to boot older operating systems:

I had already set them to -1 but still does not see the OS. Could it depend on the version i downloaded of BigSur?

With the command:
python macrecovery.py -b Mac-E43C1C25D4880AD6 -m 00000000000000000 download

should download the latest version.
Or so it says in the guide...

EDIT
But strangely with my EFI folder and my config file (which I created following the guide) the OS is detected by OpenCore

UPDATE

I did it.

I had to change HideAuxiliary to NO in the config file and then add the NVMeFix kext to make it detect the two NVMe SSDs.

The only thing in MacOS startup (login screen) the resolution seems to be minimized, everything is very clear and bright. Once logged in, the resolution changes automatically, even passing to 240hz.
But I think it depends on a setting of MacOS and not of the config file.

For the rest, everything would seem to really work.
Great job scope666. Thanks again.

Aye nice.
Just to point out, NVMeFix didn't made you detect the NVMe in OpenCore. This is a kext, not a UEFI driver, and it fixes power management on macOS . I'm pretty sure that disabling HideAuxiliary as well as configuring APFS MinDate and MinVersion and having HfsPlus.efi did the job.

Regarding the 240Hz as well as the resolution, I have a similar "issue", but never deep investigated onto it.

In any case, thank you so much for testing the EFI ^^
