If you haven't had any luck with this, here's a few commands I entered at the prompt as pictured above:
VBoxManage modifyvm "Macky-Mac" --firmware efi64
VBoxManage setextradata "Macky-Mac" VBoxInternal2/EfiGopMode 3
VBoxManage setextradata "Macky-Mac"
Substitute the name of your virtual machine for Macky-Mac. Also, the #3 at the end of the second command denotes 1280x1024. I think 4 is 1440x900. I had done everything per this tutorial to no avail. I'm not altogether sure what this did as I couldn't see any changes in the vbox-prev file associated with the virtual machine.
