GPS tech (Garmin, Hammerhead, Wahoo, RWGPS, etc)

I'm on OS10.7.5 which Apple have released some updates for. Now my Chrome extensions aren't working properly and Chrome cannot load Garmin Communicator – the plugin needed for Garmin Connect courses to be loaded onto my Garmin Edge 500.

Has anyone else had similar problems?

Am I likely to get a reply from Garmin help or is that wishful thinking?

Yeap same problem.

I already had the plugin installed and haven't updated anything on my computer afaik. I think it's a garmin issue possibly and not an apple one.

Actually I think the issue for me was a chrome update. Seems some people hve had issues with 64bit browsers.
I can upload on firefox(mac) without any issues.
