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.

Hi fpelletier,

Looking at the comment chain are you still having the issue with the .dmg file not opening? The firmware file should be able to open in OS 12 with Intel or M1 chips. If it still isn't opening one more thing to try would be to bring up the file directly in Finder. When you bring it up switch Finder to either column or list view, navigate to the .dmg file, and when you open it the contents should be listed below or to the side of the .dmg file. 

I also see a Me Too note under your post about the camera not reading the firmware update. 

There are a few things to check when updating the firmware. When you transfer the firmware file to your SD card you only transfer the file ending in .fir. If you transferred anything else the camera will not be able to read it. The only one that should be put on the memory card is the .fir file.

The other thing is to double check the location of the .fir file on the memory card. If it is in the root folder it should be listed with the DCIM and MISC folders on the memory card. If it is inside of either of those folders the camera will not be able to read it. Instructions on checking those two items are included in with the firmware file you downloaded. In the folder will be the .fir file and a folder with the instructions.

Having the same problem again with new firmware. Amazing that Canon don't allow you to update on a Mac!

I'm having the same issue for the last two firmware updates I have not been able to dismount the .dmg file.  I double click the file as I normally do with a .dmg file but nothing happens.    I have a macbook pro with the M1Max chip.     Canon needs to make sure these files work on everyone's computers especially the new Macbooks.      Now there are two updates that I can't load on my R6 camera's  because of not being able to open your files.   Please Canon fix your files so we can all enjoy the updates!!!    Thank you.

I tested on MBP, M1.  Ventura.  No issues opening .dmg

FYI FW v1.7.0 for the R6 is available as of 12-7-2022

That is very odd that it would work on your M1 but not on mine that has the exact same specs.    I have opened other .dmg files with no problems but the ones from Canon don't open.   Computers ughhhhhh!!!!!!

It appears on desktop but doesn't decompress when double clicked

A .DMG file is an executable.  It does mount and will appear on your desktop when clicked as long as you have hard disk selected in Finder preferences.  You then copy the .FIR file to the root of your SD card to perform the firmware update.  

This difference was caused by changes Apple made to it's OS.  The CPU type M series or Intel does not matter.  You just need to enable the hard disk option in Finder before clicking the .DMG file.

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.
