NVRAM variables don’t persist between reboots #31

I am having an issue whereby NVRAM variables don’t seem to persist between reboots. Having checked the OpenCore guides I followed the verification method but seems to be not working:

Can anyone with the current EFI in the repo reproduce the verification as intended?

Thanks in advance.

Hm thats very weird. Have you done any changes to the config.plist under the NVRAM section?

@jaromeyer My bad, had some updates to the repository, mainly kernel extension upgrades etc. Once I reverted to your version (besides having my personal MLB, SystemSerialNumber and SystemUUID) it seems to be working again.
