Plugins NOT showing up on MAC

[jonrocha1981]

I am new to streaming-ish. I am not an idiot when around tech, but this plugin issue for MAC is frustrating at best.

I have downloaded a multistream plugin for MAC. (obs-multi-rtmp-0.6.0.0-macos-universal.pkg) but has not shown up on my dock in OBS. I have:

-Started and restarted OBS
-Gone through the FRUSTRATING process of making sure the .so file is in the file of "plugins" under OBS (even finding these folders is a chore to begin with)
-Have found there are TWO plug in folders (one is under apps>contents>plugins, the other is under obs>file>show settings folder)

Either way, I cannot get ANY of these to show up under the dock.

Can ANYONE break this down like I am a five year old and explain why this is or what I have to do to make these plugins show up? I have a feeling it is something stupid easy, but that no one has covered over YouTube or any other forums I am have spent hours running through.
