VirtualBox Changing OSX guest screen resolution:

1) The guest must be turned off.
2) VBoxManage setextradata “Yosemite” VBoxInternal2/EfiGopMode N

Where N is:
0 – 640×480
1 – 800×600
2 – 1024×768
3 – 1280×1024
4 – 1440×900
5 – 1920×1200

3) This unfortunately didn’t work for me:
VBoxManage setextradata “Yosemite” CustomVideoMode1 1920x1080x32
