virt viewer for Mac

Hi. Please excuse me if this is not the right place to ask. We are using virt viewer happily from Linux, and though the Windows release sometimes has issues it seems it is maintained. There is this Mac client here: https://people.freedesktop.org/~teuf/spice-gtk-osx/ We have been reported it is outdated and somehow buggy. Is there another alternative ? Are there plans to port virt-viewer for Macs ? Thank you.
