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

[Skip70]

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.

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