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?

Try this answer, it worked for me with OS X Lion.

I'm not sure it will work for El Capitan

  • Seems like the com.apple.boot.plist and the com.chameleon.Boot.plist files are not in El Capitan anymore.
