Hello Sir, I need some help, I believe I'm doing everything ok, but I can't pass step 3 (openCore 0.6.7 EFI for Z390 Designare). After pressing F12, I can see the OpenCore picker, but after I have chosen the internal HD, it shows the Circle with the cross line.
On this step:
- At the OpenCore 0.6.7 Picker menu, select and boot the internal macOS disk.
- If everything works correctly, copy the new OpenCore EFI folder from the USB flash disk to the EFI partition of the main macOS SSD.
I want to upgrade from Catalina to Big Sur. My current version is Catalina 10.15.3
Any idea why?
Thanks, CaseySj, for all your help.
