MacOS VM on Virtualbox on Lububutu – Upgrade MacOS

A few notes from another users and forum:
1. Updates – this image is 10.13 and the latest is 10.13.6, but the update install never finishes after a reboot and it just tries to install the update, reboots, etc. Here is the fix:
1.a Install the update but shutdown instead of reboot. It will update a few things and then shut down, turning the VM off.
1.b Start the VM again, but as soon as the screen turns black, start to hammer the F12 key. Make sure your keyboard is grabbed by the VM. If you managed to hit F12 at the right time, the VirtualBox EFI should pop up. If the VM starts up normally, go back to step 3.a (yes, you have to download and reinstall the update again)
1.c Now use your arrow keys to select “Boot Manager” and hit Return, then launch the “EFI Internal Shell” from there.
Inside the shell, type the following commands:
Shell> fs1:
FS1:\> cd “macOS Install Data”
FS1:\macOS Install Data\> cd “Locked Files”
FS1:\macOS Install Data\Locked Files\> cd “Boot Files”
FS1:\macOS Install Data\Locked Files\Boot Files\> boot.efi

Essentially, Apple moved the update boot.efi and Virtualbox is running the regular boot.efi and the update doesn’t finish.

If you get “Installing High Sierra” and then a progress bar that takes about 50 minutes, you are golden. Anything else and something is messed. I successfully got the latest xCode running on the latest High Sierra in virtualbox.
