Q: Canon CR2 files no longer viewable in Finder

I shoot with a Canon 5D Mark III in raw format only. This results in a .CR2 file, Canon's defacto file appendage. This camera is listed as being supported by El Capitan according to this link: Digital camera RAW formats supported by OS X El Capitan - Apple Support

However, when I highlight a file in the Finder window, I now longer get an image preview, just a file logo. The same thing happens if I try to preview the file using the space bar. This is incredibly frustrating since I can no longer tell which images I have downloaded off a CF card or make a selection from a group of images.

How do I fix this? Is it a common problem? Everything worked fine with Yosemite.

I'm using a 2013 Mac Pro if it makes any difference.

Mac Pro, OS X El Capitan (10.11.1)

This may not help, but try Control (right) click on the Finder window and select "Show View Options"

then make sure that "Show icon preview" is checked.

Also it might take anywhere from a few seconds to a few minutes for the preview icon to populate depending on what resources your Mac has available.

thanks for the suggestion den.thed but alas, that box was already checked.

as for resources, there's at least 6-10gb of RAM available at any time and plenty of processing power on this machine to render any previews. Apps like Bridge and Lightroom operate quite quickly

Send feedback to Apple. They won't answer, but at least they will know there is a problem.
