I have never had a problem with my ANT+ stick, but today’s update it is not even trying to connect to my cadence monitor (yellow hazard sign on ANT+ icon). I am running a MAC so no drivers involved.
Not running garmin or trainer road or anything like that from this computer. Really frustrated!
I used my iPhone the last couple of times. I just double checked my MacBook. Using the latest update, everything works. The ANT+ dongle was detected. I was also able to pair to my powermeter, etc…
Maybe coincidentally your ANT+ stick died? Do you have another computer or ANT+ stick you can test with?
