AeroPod, PowerPod and Newton

I understand how to save it, just not how to export it then to the TP device manager or the TP online program. When I try to use the device manager it will not allow me to select a .csv file.

I am having a problem figuring out how to export files into Training Peaks on my Mac. I see how to do it on windows, but as I try to do it the same it does not recognize it as a file that I can bring into the device manager or that I can drag into the device manager. Any help is greatly appreciated.
