When I try to start Test.jar apple shows up with the error The Java JAR file “Test.jar” could not be started. when I do java version it says…
java version "15" 2020-09-15 Java(TM) SE Runtime Environment (build 15+36-1562) Java HotSpot(TM) 64-Bit Server VM (build 15+36-1562, mixed mode, sharing)
I have seen other questions and posts, but no one seems to answer the question. I am running macOS Catalina 10.15.7
The file I’m trying to run is https://cdn.cosmicclient.com/download/Launcher.jar
I would appreciate some help playing Minecraft. Any ideas?
