Can you post your complete FreeCAD info as explained here: viewtopic.php?f=3&t=2264
There have been a couple of backports to the 0.16 release branch, at least one that was related to an OSX crash.
Also, I don't know how to do either on OSX, but can you start FreeCAD from a terminal and paste the contents after the crash, or even better yet start /FreeCAD with gdb and provide the stack trace after the crash.
