I have a XT 640 V2   for some reason I cannot see the photos and videos on my Mac.  Mac says unreadable   I can see them on a windows computer    did not have this problem before the upgrade    thanks for any help

Hi bro, i just read this, i had the same problem and it came from the SD Card Capacity, i was using a 64GB SD Card on the XT, reading about this XT supports only 32GB SD Card
