O ye of little faith....
The developers watch this forum regularly. It is the main source of developer feedback during Beta testing.
I see your Flyspray task. It is in the right place, and will be closed in some manner before the next Release.
Meanwhile, what we need to address the current
issue is your logfile, your opencpn.conf file, and your navobj.xml file. One or more of these files is causing the hang issue. If you delete them all, OpenCPN should start back up with defaults, and you will be back up and running.
I doubt this is a Mac specific issue. Probably some mal-formed xml in the navobj file. Lets take a look.
