Trying to Make a Server on Mac


Recommended Posts


I've created a custom modpack and a server to go along with it for my friends and I. I have the server on my regular computer and everything works fine, but since I have to allocate quite a bit of RAM for it, I decided to try to move the server to my MacBook so I can play without constant lag spikes. I downloaded the zipped version of the server's folder on my mac, and followed the proper procedure to create a mac server (creating start.command and giving it executable perms) but for some reason, I'm getting an error in launch.

A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException
