 ### Network sharing
 Another way of sharing files between the host and guest (including support for macOS 12) is to use the network file sharing feature of macOS running on the host. You can do it from "System Preferences" under the "Sharing" category. Check out [Apple's user guide](https://support.apple.com/guide/mac-help/set-up-file-sharing-on-mac-mh17131/mac) for more details. Once a network share is set up, your macOS guest can connect to it just like any other Mac.
