This is a command line executable. After downloading the file you might have to change it to an executable (chmod). You also have to allow it to run (System Preferences / Security).
Download track logs from Brauniger/Flytec, IQ Basic, Digifly Air, MLR, Flymaster and Ascent.

Download the file (click on GpsDump.1.02). The file GpsDumpMac64.1.02 will most likely be downloaded to the Downloads folder.
Open a terminal window. Go to the Downloads folder ("cd ~/Downloads"). Make the file GpsDumpMac64.1.02 executable ("chmod u+x GpsDumpMac64.1.02").
Start System Preferences - Security & Privacy - General. Look for "GpsDumpMac64.1.02 was blocked from use because it is not from an identified developer". Open the lock. Click on "Allow Anyway". Close the lock.
In the terminal window execute "./GpsDumpMac64.1.02". A pop up window with a warning is showed. Click "Open". GpsDump should now have printed a menu in the terminal window.
You only do the above when you download GpsDump.
Connect your instrument to your Mac. Execute "ls -al /dev/cu.*" in the terminal window. You should see a list of devices, one of them is your instrument. When I connect my Flymaster the device /dev/cu.usbmodem0000001 is listed. Take a note of the text after "/dev/", in my case "usbmodem0000001".
The basic command for downloading a track from a Flymaster (new models) is then "./GpsDumpMac64.1.02 -gyn -cu.usbmodem0000001 -l
The name of the interface port will in most cases be the same if you connect your instrument to the same USB interface each time.
