Hi there flyers, first post, I have a possibly very dumb question driving me crazy. Want to update my firmware, I think I understand the whole process but can't get past "copy the .bin file to your SD card." The card will not accept or read the bin file, a 'no go' symbol comes up and it won't transfer. I am on Mac, have flown and used the SD card many times. I formatted the SD card in my quad, downloaded the firmware zip file from DJI, open that and see the .bin file. But when I try to copy or drag the .bin file onto the formatted SD card (in fat32), it won't accept it so I can't even get started. I've read and watched videos of people casually dragging the .bin file onto the SD card, but it just won't do it and I don't know why at all. Thanks for any help, seems like something real simple I'm missing.
