Hello hello! So, I've absolutely loved the demo of the game and I've recently purchased chapter two, but I'm having technical difficulties as my mac just... won't open it. The game downloads fine. I unzipped it fine. I double clicked it to open... and nothing. I'm staring at the bouncing game icon as its taunting me. This is more painful than anything Cirrus could put me through (taking it as a challenge?) Help please??? It just says application not responding.
Unfortunately, I'm not a Mac user so I can only pass along information second-hand that may be able to help you. You may be able to right-click the icon and choose "Show Package Contents", and then go into the folders to find a different launcher that should? work.
In this case, I went into the Obscura.app folder, then Contents, and then MacOS, and there was a file called Obscura there, which hopefully launch the game? I'm afraid I can only be of so much help in this case; this is a tutorial from a dev friend of ours who has been able to use this method before, but I can't test it on my own.
