Troubleshooting slow tethering performance on macOS

QUESTION

There is significant delay between when I fire the shutter on my tethered camera and when the image is rendered fully in Capture One. How can I improve this?

ANSWER

First, check this article as most of the solutions found there will resolve any tethering issues, including slow performance: Tethering problems: the camera is not connected or frequently disconnected

In addition to this, check that the camera is connected over the proper USB protocol. In System Profiler, under the USB section, find the camera and the Speed:

This indicates what speed the camera is connected:

• 12Mb/s: USB 1.1
• 480Mb/s: USB 2
• 5Gb/s: USB 3

If the camera is connecting slower than it should be, reconnect it and refresh System Profiler (via cmd+R). If it persists, try a different port on the machine, preferably on a different USB bus.
