trying to connect to an Apple iMac running Catalina. We get a connection and I can view their destop, but I cannot see any of the pull-down menus from my device. We both have the most current TeamViewer app installed (v14.6.2452). I am running on an Apple Macbook Pro Mid-2012 running OS X 10.12.6 and the other device is an Apple iMac running OS X 10.15. Any ideas? Thank you....
