The latest update to Kuuvik Capture is now available on the Mac App Store. It brings complete Canon EOS 5D Mark IV support, including the ability to shoot and display Dual Pixel RAW files. I’d recommend to check out my former notes on 5D Mark IV RAW files.
This release also boosts RAW decoding and camera communication performance – you can find more details on these improvements in my previous post.
A new preference
As a first step toward JPG support, you can now shoot RAW+JPG (Large/Fine) in the camera. Since Kuuvik Capture works from the RAW file only to display the histogram and highlight/shadow warnings, just the RAW files are downloaded even if you shoot RAW+JPG. JPG files are saved to the memory card.
You can switch between RAW (the default) and RAW+JPG Large/Fine in Preferences.
Notes on macOS 10.12 Sierra
Usually I’m not doing this, but this time I highly recommend NOT to upgrade to macOS 10.12. At the time of writing the new OS has way too many bugs, two of which affecting Kuuvik Capture users specifically.
1) Connecting the 5D Mark IV via USB to an app, and then quitting the app will leave the camera in an inconsistent state, and no app will be able to connect to the camera until the USB cable is disconnected and plugged in, or the camera is turned off and back on, or the memory card door opened and closed.
This only happens with the 5D Mark IV and on macOS 10.12 with the USB connection. The same camera on 10.11 works fine, all other cameras we’ve tried on 10.12 work fine. Even the Wi-Fi connection works fine – well, it’s not a surprise since it doesn’t use the flaky macOS PTP/IP stack.
It seems that macOS forgets to close the session with the camera. There is no workaround to the issue, other than the things mentioned above that actually break the session on the camera side.
2) On some computers (MacBook Pro 15″ Retina Mid-2012 for example) 5DS/R files are not displayed at all.
This is due to a bug in the macOS video driver, and thus happens only on some machines. There’s a workaround, however. Kuuvik Capture can downsize there files to be just 24 megapixels for display. Just open the Terminal app, and enter the following command:
defaults write com.direstudio.KuuvikCapture forceLargeImageDownsizing 1
Once Apple fixes the bug, you can turn downsizing off by the following command:
defaults write com.direstudio.KuuvikCapture forceLargeImageDownsizing 0
Of course we are working on to get these issues fixed, but until then the best remedy is to avoid upgrading.
Update 10/26/2016: macOS 10.12.1 does not resolve these issues.
The update is free for existing Kuuvik Capture 2 customers. New users can download Kuuvik Capture 2 from the Mac App Store for $79.99 / €79.99 / £59.99.
