As above, the moment I launch the game it just instantly closes without showing anything. If I launch it directly (without the itch app) it remains open but it sits in the dock and there's no game windows or anything else visible. I hadn't seen this posted already so I don't know if it's a bug on my end or what.
macOS — Game launches and immediately closes (no screen visible, just immediately crashes)
It crashes instantly through the itch app too? Hmmmmmm. And it doesn't throw an error popup? Does itch give any "Examine the cause of failure" dialog or something when it crashes?
Nope, it just literally opens for half a second, the icon bounces a couple times in the dock, and then the icon closes. If I open it directly, the application remains in the dock but doesn't show any windows or anything (it doesn't seem to be locked up, however) and nothing happens.
Thanks for posting this, think I'm starting to finally get some leads on why the macOS version is being so difficult...
Going to try out a few things over the weekend to see if I can get it launching more reliably.
Since it looks like you at least have a version of Java installed on your machine, see if running this from the Terminal works...
> java -XstartOnFirstThread -jar desktop-1.0.jar
(Assuming that you have the Terminal navigated to the same folder as the jar file)
There might also still be an issue where I'm using a AWT/Swing popup to show crash error messages... but worth trying.
I get the following error:
java(3906,0x7fff99cea340) malloc: *** error for object 0x123b69140: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
 3906 abort java -XstartOnFirstThread -jar desktop-1.0.jar
Here's the Java version on my machine
java version "1.8.0_101" Java(TM) SE Runtime Environment (build 1.8.0_101-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)
