Okay, apologies for not knowing, i'm having a difficult time navigating through these forums.
I am using MacOS, so i'm not sure where to find my logs.
I did some basic research, but could not find anything on my specific problem. I found a thread on THIS forum, and replied to it, not realising that it was old, and decided to make this thread.
Everything i know is that i put my mods in the right spot, installed forge by pressing the "installer" button on the site for 1.14.2, I can launch minecraft fine, and on the main screen it shows up that the mods are recognised, but they just don't seem to work in game.
I am playing with Optifine (which works fine when i use it as a singular client), and i'm also using the capes mod found here, and as far as I'm concerned I'm not doing anything incorrectly.
Hopefully that's useful to help youg uys help me
