Agree with above poster.
If it's confirmed, in fact, that there's no fix coming, is Obsidian offering refunds to those who purchased the game to play on a Mac? At this point, it's really unplayable at such low resolutions on a 2800 x 1800 Macbook Pro retina. It's unfortunate because I really loved the game, so ideally there'd be some kind of fix to bump the resolution back up.
