As seen above. It won't connect - Mac sees the watch, it charges, Garmin software just won't recognize it. Have uninstalled/reinstalled, restarted, etc - I have, in other words, done all of the things the first five comments will tell me to do anyhow.
Only possible issue I see is that the Garmin cable is USB 2.0, so I have to use an adapter/hub to connect it to any computer made in the last decade.
