Project Eternity - $1.6M, Mac version and more unlocked

Obsidian's Project Eternity Kickstarter has just ticked past $1.6M, unlocking the following stretch goals:

1.6 million, a Mac Version of Project Eternity and The Story Grows!
We've listened and we’ll make a Mac version of the game at this tier. We're also going to add a new major storyline along with new quests, locations, NPCs, and unique loot (special histories everyone?).

Looking forward to $1.8M, we'll get:

1.8 million, New Playable Race, Class, and Companion!
The options grow for your main character and the roster of your motley crew expands with the addition of a new companion from the selected class.
