Canon 5DMark IV timeout?

Hello everyone-
I am tethered to an iMac with a USB 3 cable to the Canon 5D Mark 4. Sometimes I get a block on the image as shown- other times, the connection is lost between Capture One 11 and the camera. If I try turning off the camera, the display says something about 'Recording' an image and never seems to end. So I turnoff the camera, remove the cable, sometimes restart the iMac and start all over. How can I get this all to behave?

This seems to be a signal/power issue. USB3 is more prone to that then USB2. iMacs are also more likely to have this problem.

You could use a USB repeater, go for the best cable, make sure you do not exceed the 3 meter 10" limit for USB3, or use a different computer (no offence).

I would just say that your best solution is to look at the Ninja Atomos recorders. You can go as long as you want as well as record to both memory cards in your camera and the external recorder.
