Forge Folder instead of Installer

[RolyPoly]

I'm trying to get pixelmon working for my son and having a hard time getting forge installed correctly. I've youtubed for hours trying to figure it out on my own without success.

I use a mac, I've updated java and mincraft to version 1.11.2. I've downloaded the appropriate version of Forge. I get around the firewall prohibiting me from opening it but when I double click the .jar file to install it opens a file instead of a installer program. I could get the rest if I can get it installed but can't circumvent this. Help?

java -jar {jar name, including .jar extension}

Open terminal, navigate to the folder the jar is in, and run it like so.

I'm sorry, I'm a super moron judging by your signature.  I don't understand your instruction. 

I think I'll just tell my son pokemon are no longer a part of minecraft.

Moron I'll remain.

Thanks anyways... I think.
