Hi folks,

I am struggling with OpenCore, I've followed the guide from OpenCore themselves but I cannot get it to boot, tried to enable a NVRAM reset but I cannot workout how to enable it, every time I boot I Keep getting the following OC Failed to bootstrap SB NVRAM values any ideas ?

maybe upload a screenshot and your EFI?

Here is the EFI.

Thanks.

For some reason it won't allow me to upload the EFI folder?

Ok now it's uploaded the EFI zip, for some reason it won't upload it in the previous post. Sorry about this.

Just tried that, I am now at the boot loader screen but doesn't show the MacOS boot drive only UEFI Shell so getting a bit further.

Quick forum search shows HFS.efi is missing, which I don't have.

I am currently running Catalina until I get OC working properly then I will do a fresh install on the new SSD.
