Okay, just finished 12.2 beta 2 upgrade...
- Here's a link to the OpenCore 0.7.6 EFI folder for this system. Simply download the file called OC-076-DESIGNARE-Z390.zip
- Then follow these instructions to configure the EFI folder. These instructions are for 0.7.5, but apply to 0.7.6 as well.
To boot from the USB flash disk it is
not necessary to have Monterey installer on it. We only need to copy the configured EFI folder to the EFI partition of the USB flash disk. Then press
F12 at Gigabyte Splash Screen to open the BIOS boot menu and select the USB disk.
At the OpenCore Picker, check the bottom right corner for the release version. Then select the macOS boot disk. Once existing macOS has booted up we can take the next step.
Please use
OpenCore Configurator 2.55.0.0 and ensure that the title bar says
0.7.6 Release Configuration as shown:
