I just purchased the game from Arcen (not Steam, Humble, etc) and I'm getting a black window with a system title bar on launch. The game doesn't crash, but there's a black screen with no sound and nothing else happens. I eventually quit the app with CMD-Q. This is on a laptop with no external monitor connected. The same thing happens when I try on a newer machine (also a laptop) with the same OS.
Here are my system specs:
Operating System: macOS Sierra (10.12.1)
Processor: 2.4 GHz Intel Core 2 Duo
RAM: 8GB
Video: NVIDIA GeForce 320M 256 MB
Grasping at straws, I reinstalled an old version of Bionic Dues I have laying around... and had the same thing happen. That was working under 10.11.x. Could this be a compatibility issue with the latest release of macOS? Is there any additional information that may be helpful?
