A QUESTION FOR 1DX-2 USERS WHO ALSO USE MACS PLEASE :
I have CFast 2.0 and CF cards loaded, both SanDisk Extreme PRO 64GB. I only record RAW and to the CFast card with the CF card for overflow (which is rare).
My Macs are an iMac and a MacBook Pro, both running macOS High Sierra 10.13.6. I connect to upload images into Apple's Image Capture via the Canon supplied USB cable. My iMac only has USB-2 whereas my laptop has USB-3 ports.
The problem is that Image Capture rarely sees/loads the files from my camera's CFast card, although randomly '1 time out of 20' it occasionally does. So my workaround is to first copy ('Transfer' in the blue Menu) all the image files from the CFast to the CF card within the 1DX-2 while it is switched off and disconnected, and then the CR2 files can arrive on my Mac. The problem also existed when both my Macs were running the previous OS.
I always religiously reformat both cards before using my camera again.
The only reason I can think of is that the macOS does not support CFast cards? Any suggestions or help would be appreciated.
Thanks,
Robin
