Hello,
I have a Dell Optiplex 3010 SFF with an i5 processor (upgraded) and an Nvidia GTX 1050 ti graphics card.
I can boot on High Sierra with my actual EFI, but the system only starts once in four. I often get an error "error loading kernel cache 0x9" when booting and I have to restart the system several times to boot normally.
I attach my current EFI if someone can tell me what is wrong with it... I'm a novice... If someone has an EFI working for High Sierra I'm very interested.
Thank you in advance for your help and for all the resources in this forum.
