chris1111 Posted June 9, 2023 Share Posted June 9, 2023 As long as you use a pre-made EFI on Github, you might as well use one that's made for your PC https://github.com/YeeWee/DELL-3070MFF-EFI-OpenCore 1 Quote Link to comment https://www.insanelymac.com/forum/topic/356908-dell-optiplex-3070-mff-trouble-upgrading-to-ventura/#findComment-2805994 Share on other sites More sharing options...

Bad luck of mine.
