Tonido does not run in my iMac mid 2011 MacOS Sierra 10.12.4

[Felo]

I have followed your manual instructions (Install in the app folder). But, when I open Tonido won't do anything. I see the little sun in the top bar. However, when I try to click on it it will only give me the mac spinball. I have to force exit the process from activity monitor to uninstall and re-install but i have the same results.

Can you plese help get Tonido working on my system?
