I'm in a Mac, I've properly used two different versions of 1.8.9 (which are the recommended ones) and when I click play, it loads, and then crashes. When that happens, what appears is: It looks like you are using an unsupported modified version of the game.
Under that it says in a small orange box: The game crashed whilst initializing the game Error: java.lang.NoClassDefFoundError: caa and when I click View crash report, nothing happens. It's just a decoration. I right click looking for a link or something, nothing. Can anyone help me?
