I managed to install OS X on Virtualbox and it works fine for my purpose, which is basically trying to be cool. Anyway, I wanted to optimize the resolution for OSX.
This worked fine
VBoxManage setextradata "VM name" VBoxInternal2/EfiGopMode N
But that only sets the resolution of the OSX to some default resolutions (n=0,1,2,3,4,5 corresponding to 640x480, 800x600, 1024x768, 1280x1024, 1440x900, ect)
Is there a way to set the Mac OS guest to 1920 - 1080 for virtualbox?
