This is me wrestling with the Minecraft launcher by rowan_peterPosted onJuly 17, 2013July 21, 2013 This is me wrestling with the Minecraft launcher. I’ve downloaded the latest installer, installed the latest version of Java and even got busy in the Terminal as prescribed in the forums. Nuthin’. First, I installed the old Minecraft launcher. Success, but I couldn’t connect to a server with my old installation. I then downloaded the new installer and launched Minecraft. It worked!
