#Virtualbox sierra os how to
This post was inspired by another blog post documenting similar instructions on how to enter the macOS Recovery in VirtualBox. In case VirtualBox crashes with “Guru Meditation: VERR_IEM_INSTR_NOT_IMPLEMENTED” on the login screen when booting the new system, update to the latest VirtualBox test build, which implements the missing instruction. 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.
#Virtualbox sierra os install
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. If you managed to hit F12 at the right time, the VirtualBox EFI should pop up.Make sure your keyboard is grabbed by the VM. As soon as the screen turns black, start to hammer the F12 key.Open “Install macOS 10.13 Beta.app”, click through until you get to “Restart”.The result is that you can click through “Install macOS 10.13 Beta.app”, but after the restart the old system comes up as if nothing happened.įollow these steps to get around this problem: It looks like the EFI implementation of VirtualBox does not honor the way macOS wants to select the startup disk/volume/startup script or in whatever way that is actually supposed to work. The problem preventing the upgrade appears to be the boot sequence in VirtualBox. This blog post will describe how to upgrade a Sierra VM to High Sierra.
However, this proved to be difficult with the usual ways. Now that macOS 10.13 High Sierra is in Beta, I wanted to upgrade my VM to this new release. For testing purposes, I have a VM in VirtualBox currently runnning macOS 10.12 Sierra.
