Hi
The Mac version has been rolled back to v1.1.0, and should now be playable. The only thing missing from the newer version is gamepad support (which was designed for Windows + Xbox 360 controller anyway so there should be no difference.)
A fix for the latest Mac version is being worked on and will be up soon, but until then it is safe to proceed with version 1.1.0 (labelled v1.1 in-game)
