Hello everyone, since yesterday i've been doing a deep search through every forum and i haven't been able to find a solution to this; i've read about a lot of people having that black screen when they start episode 2 or the DLC, but mine's shows up at the moment i start the game. I bought TWD through Steam and played for about 6 hours until i got to episode 3, after that i closed the game and never started again. I'm running it on MacOS 10.9.3 Mavericks. I have already tried to uninstall several times, change prefs.prop, delete saves, i've even deleted Steam totally and re-downloaded everything without Steam cloud, but it keeps on showing that black screen. I've uploaded the trace generated by your support script and uploaded here: http://www.sendspace.com/file/yzh5oh
Hope you can help me.
