MacBook Access to Fenix files?

When I connect my Edge 1030 to my MacBook I get to see the files and can transfer .fit files to the computer and manipulate them with Fitfile Tools etc. It mounts the Edge as a drive. Why can't the Fenix behave similarly? The work around is to use Activity Monitor to kill Garmin Express and then Open MTP to download the files. Just curious if anyone can explain the different behaviour of the 2 Garmin products.
