I recently switched to MAC from Windows and am loading all my plugins. I used Sam’s plugins, Bolt Maker that I found in SU Extensions, and another called Hole in The Wall that I have not been able to find.
In my Windows SU plugin install there was an SDM Tools menu with edge, face, corG, Misc Tool menu items. Under the Face tool was the Hole In The Wall.
This is a nice plugin because it allowed me to make holes in my components without having to edit the component and make a hole using SU.
