[virtual-machine] How to install Guest addition in Mac OS as guest and Windows machine as host

Before you start, close VirtualBox! After those manipulations start VB as Administrator!


  1. Run CMD as Administrator
  2. Use lines below one by one:
  • cd "C:\Program Files\Oracle\Virtualbox"
  • VBoxManage setextradata “macOS_Catalina” VBoxInternal2/EfiGraphicsResolution 1920x1080

Description:

  • macOS_Catalina - insert your VB machine name.

  • 1920x1080 - put here your Screen Resolution.

Cheers!
