When I double click the white file I get this pop up. Am I not to open it, but just drag it to my blank SD card?Screenshot 2024-05-26 at 11.55.57 AM.png
I'm running into this same issue, as my MAC is Sonoma 14.2.1 only offers utility, no firmware for my 6D Mark II. Are you sure I can go to the previous Mac option to run the firmware offered?
