Hey,

I'm trying to add LabyMod 4 on my M1 mac. I downloaded the .jar file and executed it, but I'm stuck on this step, because I can't select the Prism Launcher App.

I know this is supposed to be the MultiMC executable that is probably the reason why it doesn't work. In that case, how can I add LabyMod 4 on my Prism Launcher ?

Operating System: macOS
\LabyMod Version: 4.
\Minecraft Version: 1.8.9
