Help Uploading images with Canon EOS 7D MKII to Imac with Catalina

[Christhephotog]

All of a sudden I can no longer upload images from my Canon EOS 7D MKII to my I mac using the Catalina operating system. I get a USB Accesories Disabled Message. I've unplugged all of the USB cords and it still gives the same message.

After Further specification checking it appears that a 7DMkII may not record in C-RAW, but its "RAW" format may be different from the "RAW" format used in the old 7D, so it might still be a image format issue.  You might try shooting a couple of jPEGs on the 7DMkII and see if your iMac will read them.
