Running L6.10b1 on Mac OS X 10.11.2
When I first installed the update the application kept on hanging and needing to be force quit. I got samplings of logs for a couple of those times... Eventually that cleared up to where it seemed workable, but now whenever I work offline the "preparing library" indicator remains displayed indefinitely and My Passage Guide totally fails. Every section refuses to expand, sitting there "working" for many minutes (see screen shot).

here are logs...the most recent ones are of working offline.
