OBS Plugin Installation on MacOS does not show

[hypercube]

I installed the following free OBS plugins from the following sites.

Tokyo Dawn Labs

High quality audio processors made with love. Compatible with VST, Audio-Unit and AAX audio plugin hosts, Windows and Mac OS.

Wider

Wider is a unique stereo “mono-compatible” plugin. Any signal that has been extended will always remain in phase, even if summed to mono.

polyversemusic.com

In both the cases, I was given a macOS specific .dmg file

I ran the dmg file on my mac, the installation was successful, however I could not see the plugin in OBS where the audio mixer was supposed to show them

What is the problem and how do i fix it. Where is the installer installing these plugins and how come I dont see them ?

My system information is
MaC OS Mohave
Version 10.14.6

Mac Pro

OBS Version
26.1.2 ( 64 Bit Version)

Try opening Garageband. That should trigger a plug-in scan.

OBS at this stage only offers VST 2.x versions of plugins to be used as third party, not all manufactures have these versions. I use Fuse Audio Labs plugins inside OBS with great success.
