How do I resolve an unknown boot issue on iMac 2009?
I’m trying to understand what this means and how I can bypass or fix this as I can’t find anything except two images online one of wich says to boot into efi but can’t find same images while searching for this. And it won’t let me upload pictures or video here for some reason. Can I email someone? It’s a iMac 2009
