Can't install download onto two Mac minis, running Mac Big Sur either on Intel of M1

I tried Add plugins to lrclassic: nothing there except installer which I know isn’t the plug in and of course won’t load.

You need to NAVIGATE to the folder where the plugin is. There are step by step instructions in the link I provided. I’ will quote that here for your convenience:

• In the plugin manager, you need to find the plugin file (which will have an extension of .lrplugin). You can do this by navigating back to your home directory, which will be your username (in my case, it is “nathan”). You can get there quickly by clicking the dropdown menu at the top of the plugin manager file dialog box, and selecting your username.
  
• Then, navigate to the Plugins directory.

• Inside, you will see the NegativeLabPro.lrplugin file. Add this.
