EOS Utility 2 has always worked fine for me, providing an easy way to download new images from my 70D. But after upgrading from Mojave (macos 10.14.6) to Catalina (10.15.2), the app still launches, but when I connect the camera, I get 30 seconds or so of busy indicator, then "Failed to communicate with camera. Check connections." I can get images off the card by removing the card and using a card reader, but I'd like to continue using the Utility 2 app. Any ideas?
MacBook Pro 13-Inch "Core i5" 2.3 Mid-2017
EOS Utility 2 v. 2.14.31
camera firmware 1.1.3.

This latest update from Apple has been a major headache for a great number of applications, not just Canon. Keep checking for updates from Canon and Apple.
If you know how to undo the latest Apple update, then do that. Otherwise, you will have to suffer along with the rest of the pack.

Indeed EOS Utility2 - v2.14.31c Supported OS's:
macOS 10.14, macOS 10.13, macOS 10.12, OS X 10.11
EOS Utility3 doesn't support the 70D (currently) and may never.

Ran into the same problem today. This page shows limited functionality for 126.96.36.199 on MacOS 10.15 with a few workaround options. I was able to use Image Capture to pull images off the camera.
