Can't connect with new Mac

I have a new Mac and tried to connect for a ride but for some reason cadence and power source wouldn’t connect. I went back to my PC and everything is fine. any idea of why this would happen and what the fix might be.


How are you connecting it Bluetooth? Ant+?

Didn’t know there was a reply here. Ant +

@deborah_nixon so you have a ant+ USB dongle? Does anything else connect, like HR?
