I only seem to have the tblz_log.txt file, not the boundless_game_log.txt one...
I've created a gist for the tblz_log file here https://gist.github.com/anonymous/bd9433467ed48594dfa7b9491e68920d
One thing I did notice this time around - I loaded the game a total of 3 times - the first 2 times, the game loaded fine and went straight in (still with white textures though), but the 3rd time, it got stuck on the "Loading..." screen with the spinning mac icon. Not sure if that is relevant?
Edit: 4th time loaded ok again (after I force quit the 3rd attempt), but upon quitting, I got a mac system error saying that boundless quit unexpectedly.
I did another gist, just in case this one holds any different information (sorry I didn't have time to compare to see if this was the case). https://gist.github.com/anonymous/09e72d31e9547145f4efac9f400840e1
