EOS r6: Firmware 1.5 dmg file will not open under MacOS 12.01

[fpelletier]

Hi Everyone,

I'm new here and posting for the first time.  I have a Canon EOS r6 and was trying to update the firmware to version 1.5.  I successfully downloaded the firmware from Canon site, but when I try to open the dmg file on my Mac, both M1 and Intel units (both have MacOS 12.01 Monterey), the dmg file will not open.  

On the canon site, I had to choose MacOS 11 just to download the file.  It seems that Canon released the firmware without support for MacOS 12 Monterey.  

Has anyone else experienced this or has successfully update their EOS R5/R6 cameras using MacOS 12.01?

Thanks for your help.

You need to look under Finder preferences, general.  You should see a popup like this.  Once you click on hard disk, it will appear on your desktop.

Hi Rick, I appreciate your confidence in your answer but i still have not gotten the .dmg to mount despite doing all the things. Hard disk is clicked and it does NOT mount. M1 Max running 13.2.1.

SOLVED:  I called Canon - they suggested i try the zip file instead. That worked like a charm.
