I've recently installed this game through Steam on my MacBook Pro (model info below). And have run into two issues, a display issue at initial startup of the game and a crash issue.
Yesterday, I played for 70 minutes according to Steam before the game froze during Chapter 1 and I had to force quit. Seconds before it froze, many of the textures had odd/out of place black & transparent checkerboard patterns.
Prior to playing today I used Steam's option to verify the local game cache (all was good) and then I played again for a bit less than an hour and ended up with the same results after completing Chapter 1 and viewing the in-game 'preview' of Chapter 2 (that is, before actually starting Chapter 2).
At this point, I uninstalled and reinstalled through Steam's process of deleting local game files and then installing. I played again (Chapter 2) for a bit less than an hour and the game crashed properly (unfortunately I did not save a copy of the app crash report).
At no point while playing or any of the crashes has my machine gotten warm or the fans spun noticeably loud as they typically do when I play other games or do something processor/graphics-card intensive.
I did generate a small Console excerpt containing the few messages that matched a search for 'wolf' (all related to the TWAU app). I also ran the support tool:
I'm running OS X 10.9.4 on a late 2013 Macbook Pro (retina). It's a high-end model with 16GB RAM and the combo onboard Intel graphics + dedicated GeForce card.
Every time I've started the game, the display is 'off' position-wise despite being fullscreen. The very first time, the resolution was set to the lowest option available (800x600 I believe) and the image displayed was positioned incorrectly, strips of the screen along the left and bottom were black and the top/right portions of the image were cut off/off-screen. Changing the resolution in the game's graphics settings resulted in the new resolution being positioned correctly on the screen. On the subsequent game starts mentioned above, the previously-set game resolution was remembered, however, the image positioning was still not matching the screen bounds and, again, changing the resolution 'fixed' it.
I'm using the laptop's built-in physical display and have never connected a separate/external display. The theoretical native resolution of the screen is 2880x1800. In the OS X preferences, it may be worth noting that I'm not using the default display resolution scaling, I have it set to "Scaled" and have the slider set to the option labeled "looks like 1680x1050" (this is one of the resolutions I had used when the game crashed). For reference, this is the setting in the System Preferences:
If there's any other information that's useful just let me know and I can get it for you. Looking forward to a resolution and I've really enjoyed the amount of the game that I've played thus far.
