+UTM's multiple display feature doesn't always work well with the Apple ARM machines.

+1. Ensure the VM is stopped - UTM won't allow settings changes on a running VM.
+2. Navigate to the Edit dialog by either:
+   - Right clicking on the VM -> Edit.
+   - Left clicking on the VM -> Click Edit button in the upper right hand corner of the UTM window.
+3. Under the Network tab, change Network mode to "Emulated VLAN".
+4. A new Port Forwarding tab should populate, use this tab to create a new port forward with guest port 22 and host port any number (initial tutorial suggests 2222).
+5. Start the VM. When startup completes, run `sudo systemctl start sshd`
+6. You can now run `ssh user@localhost -p 2222` from your host terminal to create an ssh session or `scp -P 2222 vagrant@localhost:/path/to/file /path/to/destination` to copy files to your root host.
