#29 Always crashes on OS X Sierra

[Jonathan Lovelace]

Every time I try to run PySolFC on my Mac after upgrading to Sierra, it crashes when the progress bar is about half-way through. If opened as a standard Mac application, it pops up a dialog with the following error message, and offering the two choices to "Open Console" and "Terminate."

PySolFC Error
An unexpected error has occurred during execution of the main script

error: Failed to start CoreAudio: AudioUnitSetProperty (kAudioUnitProperty_SetInputCallback)

Unfortunately nothing relevant actually gets recorded in the Console. However, if I run the program manually from the command line (for me it's /Applications/PySolFC.app/Contents/MacOS/PySolFC), it prints the following:

Traceback (most recent call last):
  File "/Applications/PySolFC.app/Contents/Resources/__boot__.py", line 158, in <module>

PySolFC worked fine (except for a couple of minor issues) in OS X El Capitan, and I presume in previous versions (this is my first Mac, and it came with El Capitan).

I strongly suspect this is the same root cause as #28, but I decided to open a new issue because the symptoms are somewhat different in the different environment.

Same issue here.
It can run, but without sound, running :
/Applications/PySolFC.app/Contents/MacOS/PySolFC --nosound
Hope this help.

I can confirm that I have the same problem, and that starting with the "-nosound" option lets the program run. Unfortunately, the prefernces option is greyed out. I have looked for a file or resouce that I can edit, but haven't located anything. Is there a way to make this change that will allow to program to start with this option from the normal icon (My wife isn't interested inlearning to use the terminal!)?

TIA
