Using Sierra on a Mac Mini to duplicate your issue with no response to Control-Click....if you are using the track pad on your MB Pro, you can get the "right-click" by using a gesture on the trackpad as well.
Try clicking the track pad using two fingers spread apart about an inch....you should be able to see what gestures are enabled by going to System Preferences.
Now let us know how that works.
FWIW, I'm using a third-party Kensington Trackball and the right click for that device works properly to get the pull down menu as your quoted procedure expects.
