Zwift Mac Not Connecting to Ant

I have been running zwift on my macbook pro with a garmin ant dongle for 12 months without issues. I have been using a garmin speed cadence sensor on a basic trainer.


I’ve now upgraded my mac to OS Sierra and noticed that ant doesn’t seam to connect. The cadence sensor is light up on the bike and working normally, however zwift just can’t find it.


Anyone have any ideas? Or similar issues?


Thanks in advance. Carl

Make sure there is no Garmin software running in the background. Garmin ANT Agent and Garmin Express software for example.
