Hi @cabral1349,
I'm using this plugin right now for a project with the current github version (that shouldn't be so different from the 0.9 release). I have not had any problems with it so far but I'm using osx 10.9.5
The error that you posted is quite strange, as it is addressing an audio plugin (that one in particular is used by Final Cut, for instance).
Try moving that plugin out of the folder where it is.
If I was you, I would downgrade the OS. Mavericks is not great but in my experience it runs better that yosemite (yet nothing like the ol' mighty snow leopard )
Best
