Tutorial voice too quiet and discusses "right" clicking on a mac

I was hanging out with someone I was introducing to the game and had them play through the tutorial. The sound effects were much louder than the tutorial's voice, making it difficult to make out what the voice was saying at times. In tutorial mode, I suggest that the voice be made louder, even if the default settings for the game are to have the voice be quieter compared to the music and sound effects.

Additionally, they were playing on a mac, but the tutorial instructions discussed left and right clicking. A mac uses a mouse with one button, so this can be confusing.
