Only Windows and Linux/Solaris guests have full GAs. if the guest is MacOS then GA shared folders have never been supported: GAs for MacOS guests officially do not exist at all. If the forum choice is not misleading, i.e. Assuming that you are referring to a VM: the Guest Additions must be installed in each VM separately, assuming that GAs are even supported for the chosen guest OS family.

It's not entirely clear whether 'VB' refers to the VirtualBox software in general or to a specific VM. If you enable port forwarding properly the shared folder is also visible for other hosts or virtual hosts in the 192.168.0.0/24 network.Mpack wrote:Your terminology is a tad confusing.

To access the folder your hosts have to talk afp, smb (or nfs - which has to be set up seperately) of course.

Let's assume the host system's only physical network interface (e.g. The protocol can be chosen by hitting the 'Options' button.ĭepending on your host system you can also configure a shared folder there.

If the default public user folder is not sufficient, add another folder and determine user permissions. Instead share a folder in the OS X/macOS guest system by enabling 'File Sharing' in System Preferences > Sharing > File Sharing. The additions can't be installed in a OS X/macOS guest.

AFAIK the shared folder feature of VirtualBox only works with the VirtualBox guest additions.
