Hi!
Unfortunately Mac isn’t an officially supported platform since I don’t own one, and I don’t have a way to compile and maintain the plugin for it. Because of this, you need to compile your own version of the plugin if you’re using MAC. It’s not showing up because MAC isn’t whitelisted by default, so you need to edit the .uplugin file and add it to supported platforms and Whitelist Platforms. After that just recompile your project, and it should work just fine. I know people that have done that successfully.
