Cannot connect with trainers

(AlZwift Swift) #1

I have been able to connect both my Lemond Revolution and my Wahoo Kickr Snap with my 2011 Macbook Pro running Mavericks (10.10.5); but I cannot connect with my 2014 Macbook Pro running El Capitan (10.11.2). The Zwift App shows both the ANT+ device “beacon” and the Pairing screen, but fails to detect the devices.
