Spark Preferences Window Not opening, Also no Sounds

I have an iMac running OSX Yosemite 10.10.3 and for some reason spark is not notifying me of incoming messages by sound (The messages still show however i get no sound) and when i try to open the preferences window to look at the sound settings nothing happens. Im really unsure whats causing the issue so any help would be really appreciated.

Thank you.

Spark on Mac Os is broken and it is not know when and whether it will be fixed (no developers for Spark). I suggest using other client on Mac OS.

Looks like i can use the native messaging app within Mac OSX to do messaging. Are you aware of a good replacement for the spark phone plugin? this is really the only piece of functionality i still need.

I don’t have experience with Mac OS, so can’t suggest anything. Jitsi has mac version and it has ita own voice chat plugin, maybe it will work for you.
