setting background ref/Image Plane? OSX3.12b

Sorry to sound so lost, but I’m trying to properly load background reference drawings for sculpting. I can’t find any instructions on how to do that in the video tutorials (did I miss that part?), and anything I’ve found searching here and in the FAQ are either dated or not coordinating with the mac 3.12b version.

Should I be working with Image Plane? I don’t have that in my plug-ins, nor can I find out how to use it.
Are there tutorials on how to operate Image Plane and Projection Master?

Again; I’m running the mac 3.12b version.
