The *dmg *.pkg etc. didn’t work for me too.
So my solution on macOS (10.11) is:
*** Install Homebrew
*** Install virt-viewer
$ brew tap jeffreywildman/homebrew-virt-manager
* Use a shell script to open console.vv file like remote-viewer.sh
#!/bin/sh -eu
set $( ls $HOME/Downloads/console*.vv | tee -a /dev/tty | tail -1)
/usr/local/bin/remote-viewer "$@" ; rm -f $HOME/Downloads/console*.vv &
because i didn’t get configured a „action“ for *.vv files.
$ remote-viewer.sh
Enhancements are welcome!
