Minecraft Forge Server crash on Startup (mac)


Recommended Posts

Hi, I'm new to creating a minecraft (1.15.2) Forge Server and each time i try to start up the Forge Server it will crash. I have accepted the EULA. And I do not have any mods installed so far. 

What is going wrong and how can I fix it?

Make sure Java 8 is installed and then either make sure the global "java" command points to that Java 8 installation or use the full path instead of just "java".

What kind of commands would i have to type into terminal? 

Sorry im quite new to all this. 

Thank you for your help though
