I haven’t run Zwift on my Mac in a while. I just fired it up and it looks like the current Zwift version actually closes Garmin Express if Zwift sees it running. Try making sure there aren’t any other Garmin utilities (or any other ANT-related software) running.
you should see something like this in the upper left, with circles radiating from the ANT stick icon to indicate that the ANT+ adapter is operative and recognized by Zwift.
is it the mac that can’t find the sensors? because it’s my iphone that has the app that is searching. so sorry to sound so clueless. Also - do not see the race screen on my laptop - only the main website telling me I have no activities…
did some reading about re-instally OSX and partitioning and whatall - way beyond my paygrade.
great read, with a happy ending! I had some similar problems, but with bluetooth. It was suggested I connect the devices through the Zwift mobil link app. That sort-of worked… I’m just writing this in case you want to try something else as a back-up. (I have the same garmin sensors as you do)
