So I've just filled the Micro SD card on my Mavic. I've tried to open it on the mac, loads. However there is no content inside the folders.

I've used all 16GB, but can't access it.

Anyone any ideas how to view the files?

Decided to reformat the card, it's working now. Lost all the files on it as expected.

Sorry for the trouble. Did you try to format the SD card directly to a PC using a card reader? Please make sure to back up your files. Kindly check the recommended SD cards below. Do you have a different SD card that we can use so that we can check what is the main issue?
