I was looking for a version of Forge for Minecraft 1.13 because I wanted to download mods for Minecraft's Update Aquatic.
Here's a link to the update.
There is a mod that does not support Mac and it is not available for 1.13.
I don't know what to do.
Forge for MC 1.13 hasn't been released yet. Just be patient.
