EOS R6 Mark II Can't get firmware to update

[Photographer-63]

Hello everyone. I'm trying to update the firmware on my two Canon R6 Mark II cameras, and I can't get it to update using the correct procedure on my Mac. I've used three (3) brand new memory cards, and nothing works. I format the card, download the firmware from the Canon website, insert the card into the camera, go to firmware settings, and follow the procedure, but the memory card isn't recognized. What could I be doing wrong, or do I need to send the cameras to Canon for repair? Any recommendations would be greatly appreciated. Thank you very much.
