How to install Guest addition in mac os as guest and windows machine as host? [closed]

Solution 1:

No, there are no guest additions available for Mac OS X on VirtualBox. However, you can get the "shared folders" using SMB. In order to do so you'll have to add a Host-Only adapter to your Mac VM and enable "File Sharing" in Mac System Preferences.

Afterwards you can access the share via the IP address that was assigned to the Host-Only adapter of the VM (check with "ifconfig" in terminal). Here's a detailed walkthrough for all this.

For USB-support you'll have to install the proprietary VirtualBox extension pack first in order to enable "USB 3.0 support" in your VM's settings.
