MaLd0n Posted March 3, 2022 Share Posted March 3, 2022 use this efi folder EFI 01.zip -Delete old EFI folder and paste new. Don't use merge files -Don't use Drag and Drop into EFI partition. Use Copy/Paste instead -Reset NVRAM one time - with OpenCore use entry "Reset Nvram" / with Clover use F11 key on boot screen Quote Link to comment https://www.insanelymac.com/forum/topic/350957-lenovo-yoga-c740-15iml-81td-wont-boot-to-catalina/#findComment-2777616 Share on other sites More sharing options...

Guest Posted March 8, 2022 Share Posted March 8, 2022 (edited) EFI is incorrect. I deleted "#" that prevents graphics patches.
