Soory for my poor English. I had a problem with my iMac Version Catalina 10.15.7 I had to get it repaired from scratch.
Since I had to download old version of Garmin Express the last one is not compatible with my iMac. I succeed to synchronise my EDGE 800.
But I can't access to my courses with my bike with Garmin Connect. There is an instability between SSO and Garmin connect and nothing appears.
Can Somebody help me to find a way to solve the problem.
