Hello everyone. I need help with istallation Big Sur 11.6.1

I have tried two ways to install: OC and Clover.

With clover it stucks after selecting install partition.

With OC it reboots after running strings.

I have read this topic many times. But I don't know where to find version 11.0.x

[Jake Lo]

11.0.x is the version of MacOS. The bootpack can be found at the bottom of the guide under 

1) 11.0 USB installer creation

• uncompress the following E6230 Big Sur OpenCore pack and copy the EFI folder to the mounted EFI partition:

Is there a way to install from an image version 11.6.1? I have already used bootpack in my attempts with version 11.6.1 and 11.5.2.

if your processor is anything other than i7-3540M, you'll need to disable SSDT-PM.aml or generate one and replace it with the same name in ACPI folder.

I tried to copy only my generated ssdt files to the ACPI folder and got the same result

Only two small files ssdt.aml and ssdt dsl

 

Last attempt after OC

Now it's Clover with 11.6.1

Only need the compiled SSDT.aml but you'll have to rename it as SSDT-PM.aml as that's what the config.plist is expecting. It's hardcoded in OC. If you want it to read SSDT.aml, then rename it in the config file.

or add it and disable SSDT-PM.aml

My guide is for any 11.x Big Sur version; I've amended the version line to that effect. At the time of writing, there was uncertainty with regards to the new version numbering adopted by Apple and it was not known whiter Big Sur would remain 11.0.x or turn to 11.x.x

I downgraded my bios now to A19 (i5-3320m). I have Big Sur.app (11.6.1), oc bootpack and clover. What should i do step by step to use 11.6.1 with clover?

Is it only one way through OC install?
