This sounds similar to the crash I am experiencing but it happens every time I try to leave the captain's cabin after character creation. My computer freezes and I don't receive the crash messages, everything locks up and I have to force shut down my computer.
MacOS 10.13.4
2.7 GHz Intel Core i7
16 GB ram
Intel HD Graphics 3000 512 MB
I turned down the graphics quality to the lowest setting
The game log ends with the same message as your repeated over and over:
GfxDevice: creating device client; threaded=1
