Macbook Pro is unable to mount SD card formated in Mavic Air but PC running windows can.  Neither Apple nor DJI customer support seem to have the desire to resolve this problem.  SD card is a Samsung EVO Select 64GB.  Macbook has no problems with same model card out of my Gopro Hero 6.  Macbook does not have a built in card reader, it's the model with 2 USB-C ports only. I'm able to download the files from drone to Macbook via wired connecton.So far I've tried:
Tried 2 different USB SD adaptors to rule out a reader problem.
Different cards (same model) formatting in both Macbook and PC.  It appears that if you don't format in the drone the dorne cannot mount the card.
Any suggestions?
