You may want to add groups/discussions for Linux and Mac development. I use Linux often and having a wide variety of people with different system configurations can help a lot -- I'd certainly be willing to help out.
Just want to second the motion of adding this simulator to the Mac. PLEASE. Love what your doing with it. I currently own a 2016 model of a MacBook Pro. I understand that the workplace graphic cards might not be suitable, but I am sure it could perform fairly decently.
