totobike Posted July 17, 2020 Share Posted July 17, 2020 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. EFI.zip Link to comment Share on other sites More sharing options...
