Mac apps commonly don't work because the SomeApp.app/Contents/MacOS/SomeExecutable doesn't have the execute permission set , but even so it wouldn't run because the jre needed replaced. Also the current build fixes the DesktopLauncher quit problem though you still need to replace the jre to get the app to not crash instantly (because of the jre issue), but again can't execute an executable if it doesn't have the execute permission which is why I made a helper script that you can just copy (it's in my posts)
