I finally got it to work. It seems that I had not allowed install somewhere in my system’s privacy and security. Sorry I can’t remember exactly which one now but that got the ball rolling. Then the insulation hung up writing scripts wouldn’t allow me to shut down. So I let it run overnight and even though it still wasn’t 100% successful, it got me to the next stage with a couple of force quits. I was able to shut down logon and see if it installed properly. One thing I noticed is that “Kensingtonworks .app”. You see the space? Very strange.
I have another issue now. Because the dongle is USB size and not see connector size, it’s not recognizing the track ball. However, I’m still able to use the track ball as a mouse. Very confusing. I think Kensington still has a lot of work to do.
