I have to do something wrong but I'm hopeless.
I updated my mac to macOS Catalina version 10.15.5.
Downloaded the latest version of Forge Pixelmon Pixelmon-1.12.2-8.0.2-universal.jar.
I ran it and I've got an error "The Java JAR file "Pixelmon-1.12.2-8.0.2-universal.jar" could not be launched.
I tried to find an error in Consle but without luck. So I reinstall my Java but still the same error.
I tried to run it from terminal from terminal and finally I've got the error at least: "no main manifest attribute"
But now I'm lost as I tried to find some help on Google but don't understand how to fix it at all. Anybody can help me?
Did you install forge?
