Now you will have to wait for the macOS Installer to finish, which may take a while. After a short moment, the installer will turn up and begin to upgrade your system from macOS 10.12 Sierra to macOS 10.13 High Sierra. With the last command, the system should continue booting. Inside the shell, type the following commands:įS1:\macOS Install Data\> cd "Locked Files"įS1:\macOS Install Data\Locked Files\> cd "Boot Files"įS1:\macOS Install Data\Locked Files\Boot Files\> boot.efi.Now use your arrow keys to select Boot Manager and hit Return, then launch the EFI Internal Shell from there.If the VM starts up normally, go back to step 2.
The problem preventing the upgrade appears to be the boot sequence in VirtualBox.
