Applications running in the background may interfere with the tethering software’s ability to connect with the camera. This includes applications that are running in application windows, as well as applications running in the background and in the Taskbar or Menu Bar. Some types of applications that are known to cause issues include, but are not limited to:
- Cloud software (i.e. Dropbox, Google Drive, etc.)
- Anti-Virus or Firewall (Defender, Avast, etc.)
- Tethering Applications (Imaging Edge, Acquire, EOS Utility, etc.)
Check to make sure you only have one tethering software application open. Having multiple tethering software applications open at the same time can cause connection issues. Some software, including many camera utility applications, may launch automatically and may only run in the Taskbar (Windows) or Menu Bar (MacOS). These applications can attempt to automatically connect to the camera even if it is not clear that they are open.
Check for software running in the background:
It is a best practice to close all software that is not actively used in tethering. Check the Dock (MacOS) or Taskbar (Windows) as well as the Menu Bar (MacOS) or System Tray (Windows) to be sure no applications are running other than your intended tethering software. The Activity Monitor (MacOS) or Task Manager (Windows) can be used to identify applications that are running in the background as well as to quit those applications.
Turn off Auto-Connect and Auto-Start features in camera software:
Some software applications have settings that allow the software to automatically launch at startup and/or launch or connect when the operating system recognizes a camera has been connected. This can cause issues connecting your camera to your intended tethering software. Be sure that any installed tethering software or camera utilities are not set to automatically start or automatically connect with the camera.
