Okay so I've been using Technic launcher for a really long time now and I really enjoy using it. Just recently my laptop broke so I bought a used iMac and I can't seem to get it working. I installed the launcher and it says: To use the "java-Jar TechnicLauncer.jar" command-line tool you need to install JDK. So I went and installed the JDK but now I have no idea what to do. I am literally the worst person with technology and I seriously have no idea what to do now. On my old laptop, I just installed it and it was ready to be used. What do I do now :/
