EOS 6D Mark II Firmware only shows as a .dmg file

Skip70 — Tue, 29 Aug 2023 12:18:20 GMT

I've downloaded the firmware but it only shows on my Mac as a .dmg file. When I click on it, it does not open further. Is this whole .dmg file what I drag to my card?

Thanks. I obviously don't want to screw this up!

Thanks for joining the conversation, Skip70!

So that the Community can help you better, we need to know exactly which Canon camera model you're using and which firmware version you're trying to install. That, and any other details you'd like to give will help the Community better understand your issue!

Sorry.

6D Mark II. I went on firmware site and 1.2.0 is what came up. I assume that is the latest.

A "dmg" is a Disk iMaGe. When you double-click it, it should reveal an item on your desktop within Finder. If not, when in Finder, access the Finder menu, then select Settings (Note: may be Preferences on older operating systems).

When the Finder Settings/Preferences window displays, select the "General" icon, and ensure you have the following items checked:

[X] Hard disks

[X] External disks

[X] CDs, DVDs, and iPods

When you find the item on your desktop, it should contain the instructions along with the firmware file. Typically, you need to copy just the firmware file itself to an SD card. But review the instructions for exact details.

Yes, those were all checked, still does not open. Next call: Mac Support!

If you've double-clicked on the .dmg and are still not seeing anything, launch the Disk Utility application. I can be found in the Utilities folder within your Applications folder. Or, type in Command-Space and type in Disk Utility followed by Return/Enter to launch it.

In the Disk Utility window, it should list all the disks currently connected to your Mac. You can also use the File menu, then Open Disk Image... option within Disk Utility to open a disk image.

(Not tech support, but I am 100% Apple) - the DMG needs to be on your Mac - either in your Downloads Folder, or on your Desktop - not on the SD card. Double click the DMG file, and it will Mount (it only looks like it flashes - but nothing "happens"). From there - on your DESKTOP, you'll see a drive icon that says "eos6d2 [something" - double click that. You'll see the .FIR file, and a folder with 5 PDF files - one is English (en).

Drag the .FIR file to the ROOT of your SD card (not in any folder - just drop it into the card)

Let me know if you need screenshots! 😊

Thanks again for the detailed alternate. Still does not open, so on phone with Apple now. I've never had problems in the past opening .dmg files.

Do you have any other .dmg files you can try? Perhaps the one you've downloaded is incomplete or has become corrupted. Though that should have generated an error message within Disk Utility.

Re: Uploading a firmware update using Mac OS

Skip70 — Tue, 29 Aug 2023 13:09:36 GMT

Yes, of course, I'm on the Mac. It does not open. Other dmg files do open, just not this one.

Thanks for all the responses, but it appears the problem is with Canon. I was able to successfully open other .dmg files from the Canon website, just not the firmware (Yes, I had the right OS selected).

I had Apple tech doing the same thing remotely on his computer and he had exactly the same problem with the firmware file.

Perhaps if Canon is monitoring this thread they can look into it.

I would recommend downloading again. I just downloaded the 1.0.2 DMG and it opened up a-ok on my Mac. Shows up as a volume named "eos6d2-v120-mac".

From Terminal, if executing the md5 command on the eos6d2-v120-mac.dmg file, it displays:

4f38ef57942d3f287c8ab9660f36aced

If you do the same from Terminal and see a different value, then somehow that file is getting mangled along the way to your computer.

Skip70 — Tue, 29 Aug 2023 13:25:12 GMT

Thanks, but I stay out of Terminal and nuclear power plant control rooms. I've downloaded it three times and the Apple tech downloaded it twice. Other .dmg files open, just not this one. Even if I did go into Terminal and find a different value on the file, it does not fix the issue. I hope Canon will monitor this and look into it.

As in the case of Ricky and Stephen the firmware file is opening / mounting for me as well. I'm using Ventura. .FIR file and instructions are present. Working as expected.

Re: EOS 6D Mark II Firmware only shows as a .dmg file

Skip70 — Tue, 29 Aug 2023 13:32:31 GMT

Well, I dunno... I open .dmg files all the time without problem, and even opened other .dmg files on the Canon website. The Apple tech also was unable to open the firmware file.

Hmmm, I wonder if someone can send the their .fir version of the file?

Re: EOS 6D Mark II Firmware only shows as a .dmg file

rs-eos — Tue, 29 Aug 2023 13:36:55 GMT

But there wouldn't be anything for Canon to do. By checking the MD5 digest, you'd know for sure if the file was somehow being modified along to the way to your Mac. Not sure what that would be though; perhaps something with your internet provider?

Or, do you have a virus checker that you have installed that is perhaps incorrectly flagging this particular DMG and then modifying it?

If you really want to avoid Terminal, do at least check the file size of the downloaded DMG (Command-I or Get Info from Finder). For my downloaded copy, it shows a size of: 38,020,608 bytes.

I downloaded the file when you said you were having problems earlier.

This is my system:
M1 Mac Mini 8GB RAM macOS Sonoma 14 Beta

Again, when you download the DMG, it will go into your Downloads folder:

Double-click it, and it will mount (it will just look like it flashes). It will then be either in Finder - on the left Nav Bar under Locations:

OR on your Desktop:

Once you've located the icon for the Disk Image, double click it and open it. You'll see the .FIR file, and a folder with PDF instructions:

Simply drag the .FIR file onto your SD card (in a card reader is the easiest way), and you're good to go!

I hope this helps, but if you need one-on-one assistance, don't hesitate to contact phone support at 800-OK-CANON (800-652-2666). They'll be happy to walk you through it!

The file that I and the Apple tech are downloading is:

eos6d2-v120.mac.dmg

Re: EOS 6D Mark II Firmware only shows as a .dmg file

Skip70 — Tue, 29 Aug 2023 13:42:41 GMT

Thanks for hanging in on this, but I went through all the virus-blocking culprits. The file size is 38M, as it should be. It doesn't explain how the Apple tech had exactly the same problem on his computer. I have no problems with other .dmg files, including two others on from the Canon site.

Re: Uploading a firmware update using Mac OS

Stephen — Tue, 29 Aug 2023 13:45:23 GMT

The file should be eos6d2-v120-mac.dmg not .mac.dmg. Are you sure you're downloading the file from the Canon USA website: https://www.usa.canon.com/support/p/eos-6d-mark-ii#idReference%3Dsoftware-drivers
