Downloaded via today, the error message says the app developer can’t be verified. :(

I get the same message. 

Fix here:  Scroll down to the last heading of the article.


Still not loading for me on Mac. Catalina, version 10.5.5

I've already allowed it from unidentified developer. (I do that step all the time.)

It opens, bounces in the dock, shows a black dot for a second, then closes. I'm looking through system.log but I don't see anything related to it. 

Same as me... really wanted to play this.


Here's the full trace log:

The game is now running when using this command instead:

cd /Applications/
java -Djava.library.path="/usr/lib/" -XstartOnFirstThread -jar desktop-1.0.jar

Ohhhhh, interesting - thank you a_v_a.  I'm gonna try and modify the launcher config to include that library path and see if it helps.

I look forward to that because, like many others, it won't start on my Mac.


I've added that library.path argument to the launcher in the macOS build labeled 0.51 "unstable" - if anyone had trouble getting the 0.50 version of the game working on macOS, give that one a shot and let me know if it works for you!  (or if it still does the same) 😬🤞

I'm having these problems with 0.51 unstable. EDIT: fixed it, not sure why this works but i moved it out of the little unzip folder and now it opens.

It works fine now!
