On Mac (15in MacBook pro, macOS 10.12.6), the dialogue and other text sits above the text bubble. Because the text is on top of that text bubble / dialogue box, it's always very hard to read. Please consider fixing this and releasing an update.
Also, the right edge of the scenes is cut off. For instance, I know there's an item on the right-hand side of Bertram's room looking at the screenshots from the game, but I can't see or interact with that edge of the screen on Mac.
