I bought it from Steam for my MacBook Pro Retina with Mountain Lion.
Subtitles and every text overlays are unreadable. Instead of text i see some colored squares.
I found many reports for this bug on Telltale Game Forums and... to this day nothing happened.
It is hard to give us some statement? Just "we're working on it" or "nope, that will never happens".
It is embarrasing for you guys that we have to ask and beg for it.
