I ran Zoipher 3.3.21933 32bit on Mac OS 10.9, it worked without major issues.
Since I upgraded to Mac OS 10.11, the application crashes in 2 out of 3 cases when I try to make a call. From the log file, I think it might be an issue with the headset - the log files say:
Thread 17 Crashed:: com.apple.audio.IOThread.client
Any thoughts, any ideas? I don't even now where to start looking for a solution...
