Fenix 6x Pro not recognized by Basecamp 4.8.12, Big Sur 11.5.1., Macbook Pro M1/Apple Silicon

Hi folks,

seems like never ending pain with Garmin devices continues with BaseCamp 4.8.12 on Big Sur 11.5.1., Macbook Pro M1/Apple Silicon. I am unable to see the watch (Fenix 6x / Tactix delta) in Basecamp at all, but in Express its working fine. In MTP USB mode, I got nothing. In Garmin USB mode i got error in com with device, but at least its visible in BaseCamp to display device details.Thats it. The watch is running lastest SW 16.70.

I tried:

  • different cables, different USB-C hubs and convertors
  • both Garmin and MTP USB modes
  • reinstalling Basecamp
  • adding Basecamp to Privacy allowing full disk access
  • removing Garmin Express completely

Any ideas?

Thank you for racional suggestions.
