from what I hear... everyone has that problems.
Some people get it working by going inside the app (right click and Show Package Contents) and running Contents/MacOS/cider_noui directly.. it launches through Terminal. Some people have reported this didn't work for them, but others have gotten it to work.
I do not have the game, but I'd suspect you could edit the Contents/Info.plist file and change the main executable from cider to cider_noui (or whatever its called) and the app would start working.
