Thanks for helping me it worked!

This: Make sure Java 8 is the one configured in the PATH variable

For booting my server... As you suggested, I would like to replace the Java 12 reference for Java 8 but not sure where to start...

in what file do I need to make the change?

when i check in the java control panel on my computer it's written that I'm on java 8 update 241 how do i change to the good version?

I'm trying to boot my server with the command bellow in the terminal app in my mac to allocate more RAM to the server but instead i get an error (its a modded server) java -Xmx1024M -Xms1024M -jar
