Friends, tell me the solution to the problem. I use the EFI folder from this theme to install Catalina on an HP Pavilion laptop (i5-1035g1, 8GB DDR4, 512GB SSD). In the beginning, everything goes well, the installation of Mac OS begins (it takes a long time). But when it is finished, after a reboot, there is no "boot from Mac OS" option in the opencore menu, but only installation again.
