Hi all I'm new to the hackintosh world. I have a Mac Mini late 2014, and I recently get a desktop as i wrote in the title. My goal is to get big sur working on the desktop machine, using opencore, but after creating the USB the pc just refuse starting installing. It stuck on that screen.
Here my EFI folder.
Thanks.
Enrico
