In reply to Andrei.

Try: VBoxManage setextradata “macOS” VBoxInternal2/EfiGraphicsResolution 1920×1080

Note: without quates.

Hi all,

In order to make method work for me I had to add quotes to VBoxInternal2/EfiGraphicsResolution parameter like this:

VBoxManage setextradata “MacOs Big Sur” “VBoxInternal2/EfiGraphicsResolution” 1920×1080

Thanks indeed for the help
