I can't import my photos from Canon 5D mark iv to Aperture 3.5.1 What is wrong?

I have Lightroom CC on a 2016 MBP 15" with OS X Sierra and have the same error message when trying to import directly to Lightroom from the Canon 5D mk IV. The solution is easy, take the card out of the camera and import the photos to Lightroom CC from a card reader. Lightroom CC has been updated to read the 5D mk IV RAW files. It would appear that current Sierra is not only unable to process the RAW files but is also unable to properly recognise the 5D mk IV hardware. Whatever, the above is a cheap and not too troublesome solution. Enjoy your new camera 🙂

The camera is not yet on the list of currently supported cameras: Digital camera RAW formats supported by OS X El Capitan - Apple Support

The Canon EOS 5D Mark III is supported, but the newer model not yet.

Once Apple releases the RAW support for this camera, it will probably require MacOS X El Capitan or the new system to come. All new RAW support versions have been released for the newest OS X version.

So you may want to upgrade to El Capitan and Aperture 3.6 while it is still possible.

Even after Apple stopped the developement for Aperture, you can still update to Aperture 3.6, if Aperture is appearing in your Purchases history and you are running El Capitan, see: Updating to Aperture 3.6 After the Release of Photos

Apple has still not added RAW support for your camera. The newest list for digital RAW support on Sierra is here: https://support.apple.com/en-us/HT207049

Adobe just added the support for Canon 5D Mark iv to Lightroom and DNG converter 9-7. http://www.canonrumors.com/adobe-releases-dng-converter-9-7-with-eos-5d-mark-iv- support/

I hope Apple will soon follow up. Can you use the software that came with your camera to develop the RAW and convert it to another lossless format like TIFF, while you are waiting?

Hi Tusim,

I think it's time you switched to Adobe Lightroom. Can't wait around for Apple to update camera raw for Aperture. The subscription is $9.99 a month for Lightroom and Photoshop. I waited to go with Adobe CC till I bought the Canon 5D Mark IV. I was using the Adobe software but the non CC versions do not work with the 5D raw files and there is no update to the older software in sight so I had to switch to CC.

Don't know why I waited so long. They work great with the new raw files in the Canon 5D4.

Let aperture go and update to Adobe CC. It's worth every penny.

An alternative to Lightroom would be DxO Optics Pro. It offers superb RAW processing and you can use it as a photo editing extension from Photos for Mac.

The "Supported Cameras" site is showing the support for your camera to be scheduled for November:

But note the footnote about sRAW and mRAW.

I am also waiting for this update. I understand there are better programs out there (which I use as well) but I want to be able to view my 5D4 RAW files in photos/aperture.

Shameful Apple, it'll be December soon.

DxO Optics Pro is now supporting the Canon EOS 5D Mk4.

If you purchase this Photos Editing Extension, you can develop the RAW files directly from Photos.

Are they RAW files? If so, I don't think Apple has come up with an update to process them. You might have to use something that does support that RAW, like an Adobe product. Or wait. Or not use RAW. Or use Adobe's free converter.

Their latest OS update support 5D MK4 for Phone and preview..., but aperture still not working for MK4 raw :(

If you updated to macOS 10.12.2, what is happening in Aperture? Does Aperture still not recognize the RAW of new photos you are trying to import? Have you tried to reprocess the RAW files already imported?

"Photo" and "preview" can read Canon 5D Mark4 raw, just the aperature can't read canon 5D mark4 raw.
