Can't find Garmin folder on Mac

Since I'm having some issues with my IQ data fields that keep getting deleted in an activity I'd like to see if the Beta software has fixed this.

When I connect the watch to the Mac via the USB cable, it syncs with Garmin Express, but it doesn't display the watch on the Mac. In the settings I have already selected "Garmin" under USB connection.

I hope someone can help me, thanks in advance for the effort.
