Hi, I am a long time user of Garmin GPS and Apple MacBook Pro. Just sold my Garmin 61 and bought a 65. I'm using Catalina OS on the Mac. I can't get my computer to recognize my Garmin. Garmin tech has been no help. They don't seem to have a clue. Several recommendations but nothing works. They said I can only have one Garmin app open on my Mac at a time. When I open Garmin Uploader, Express opens also. I quit Express but my computer will still not see my Garmin. Need help from someone who knows. Terry
