Hi, there seams to be something wrong with the latest version of Garmin Express for macOS.
Almost every time I disconnect a Fenix 3/3HR/5 it freezes and require a soft reset.
Today I found a solution for this FREEZE-problem :-)
If I first quit Garmin Express (not just click on the red x) and then unmount my Fenix the watch doesn’t freeze.
Maybe not the best solution, but it seams to work.
It wold be great if this bug was fixed in the future :-)
