FitFileExplorer is a simple open source utility to open Fit files on your mac.
The goal of the utility is to show all the information in the fit file as is. This is intended to be a tool to explore all the information available in a fit file generically rather than a user friendly way to show some summary information. The target audience is likely developers or people that like to explore raw files.
For fields that contains many entries (record, laps, etc) it will also display graphs of the data from the last column the user clicked on.
If the data contains gps coordinate, the track on a map will also be displayed.
This utility is open source on GitHub.
Support for Developer fields and Stryd power units
