Le passage du communiqué de Cyan concernant la version Mac:
Mac Version
The Mac version is a work in progress. When we started Obduction three years ago, Unreal Engine 4 included limited Mac support. While we’ve been building Obduction, Epic has been improving the Mac version of Unreal, but it is still a little raw. As a result, it would be best to think of the Mac version of Obduction as an early release. Rest assured we’ll continue working with Epic and provide updates after launch. And just FYI, if you want a better launch-day Mac experience, Obduction works great under Boot Camp.
