Big Sur: Booting an Hynix NVMe SSD

Recommended Posts

Hi,

 

This SSD is known to be incompatible, however there are few existing patches for 10.15 and 10.14.0.

I can't boot the Big Sur installer right now because of an IONVMeFamily.kext kernel panic so I was wondering if there was a way to reuse the attached kext and the patch from 10.14 to boot the installer.

 

Thank you

James

Thanks for the quick reply, I already tested this kext and I still get the kernel panic: https://github.com/acidanthera/NVMeFix/releases/tag/1.0.5

Do you know if it's possible to use an older IONVMeFamily kext like I asked? :)

Thank you

I can try older versions, but NVMeFix doesn't fix compatibility with Hynix SSD, it's not what it's meant for. This is why I would like to try to downgrade the IONVMeFamily kext to an older version

I do see in Clover Configurator --> Kernel and Kext Patches a tab ForceKextsToLoad. Assuming it's in Clover EFI 'other' folder, what would be the proper path? 

/Volumes/EFI/EFI/CLOVER/kexts/Other/IONVMeFamily.kext ?

/EFI/EFI/CLOVER/kexts/Other/IONVMeFamily.kext ?

 

Also, how do I a block a kext from s/l/e to load?

 

Thank you

James
