We’ve started the public beta for the experimental client ports to Linux and Mac. They are available as a complementary service to anyone who owns Arma 3 for Windows. Please check out the overview page[dev.arma3.com] for more details, limitations and a F.A.Q.
You can access the beta ports by installing Arma 3 while Steam is running on a port platform (main branch). Please report issues on the Feedback Tracker[feedback.arma3.com], and leave us your feedback on the forums[forums.bistudio.com]. We’re very interested to learn how the ports work on your hardware, drivers and OS versions, bad or good!Read more
