Addons not shown

I don’t know how this happened on my MAC but at some point my addons were moved from they’re proper place in the Blender package. At least I suspect that. I even removed Blender and downloaded it again and it is still doing the same thing. So here is a shot of what my add-on screen shows.

Here is the Blender package contents. I really don’t know where the add ons are supposed to go so if anyone knows that would be great.
