Hi, all. My son plays Minecraft on our Mac, but over the past few weeks he can't get the game to start. When he hits 'play' in the launcher, the screen goes dark and he has to force quit to get out of it. The error log is as follows. Many thanks in advance if anyone has a clue how to resolve this.

If on Windows, make sure to provide all of the necessary dll's as specified in the twitchsdk README. Also, make sure to set the PATH environment variable to point to the directory containing the dll's.
