I’ve seen several posts about Macs not recognizing Canon camcorders.
The following allowed me to see my camcorder in Finder and import items via drag and drop.
- Connect camcorder to power source
- connect camcorder to USB port
- Turn on camcorder
- Place camcorder in dual-mode; photo and video
- Press camera/play button
There was a delay of a few minutes while the thumbnails were created.
Afterward, I was able to see the SD card in Finder and directly access the content.
