This is done on a mac.
I'm trying to set up a pixelmon server to play with my friends, but when I try to open the forge-1.12.2-14.23.5.2768-universal.jar file it tells me that the file could not be launched. I've installed the client and server part. I think I'm all up to date etc, but I don't know what's going wrong.
All help appreciated. Thanks
