EOS R6 Mark II EOS Utility on MAC, app will not open

URM — Fri, 03 Oct 2025 02:42:35 GMT

I have an R6 Mark II and would like to use EOS Utility to quickly transfer files to my Mac. I was able to do this while running macOS Sonoma. Since then, with Sequoia and now Tahoe, I have been Unable to do so. It will download, but won't even open the app. My Mac is a 2022 M2 running Tahoe... Any suggestions?

Same computer and OS. No problems. Check that you have the latest version.

Same issue, Same OS, MacBook Air M4 and Canon R6 MII -- won't connect. The utility won't open, goes directly to locked up.
