I was wondering. Is it worth resetting NVRAM once and a while at boot ? (maybe when changing values in config.plist for ex ?)
Once again thanks for your great support and files @AudioGod
I eventually managed to clear it all and re-install big sur...
It seem that it was due to unclear NVRAM and it is now running fine (eventhough I could not get the boot audio scheme to work 😅 ).
I have a last issue, the opencore bootpicker does not select big sur by default but my other efi...
I did it 3 times on 3 different keys indeed, same result each time. 😖😫😩
May it be linked to somethinh saved in NVRAM during a previous process that is not cleared up ?
I added 'debug=0x100 -v' to boot args and discovered I get a "wake failure" as shown in the pic below , then computer reboots
found on internet that it may be due to incorrect EFI structure, missing memory driver and so on which I cannot believe as I absolutely did not alter your EFI folder...

Then I saw you v2 folder and decided to redo a fresh clean install on a new disk after all trial I did with previous one
I created the media installer, mounted the...

I also experienced very slow boot time and panic on sleep causing reboot, but I realise that I did not reset the NVRAM (I guess It may be related)
:);)
Hello,
You did great job and thanks for the EFI, far better than mine I struggled to build.
Had an Asus PCE-AC56 wifi card (seem to use BCM4352 chipset) working properly on Catalina which support seem to be broken on BigSur
Any idea or workaround to make is work on BigSur 11.2 ?
Thanks again...
