I have been trying to upload a CSV file to the Airdata website but keep getting an error message. I have a 2019 iMac with which I have generated a CSV file from a flight log file, with the intention of creating a waypoint mission file using Litchiutilities. Can anyone suggest a solution? I am guessing using an iMac is the primary cause as I have done nothing but battle with Android and my drone software. I don't have access to a PC.
