EOS Utility 3 won't open on macOS Sequoia, help!

Steve0916 — Fri, 28 Feb 2025 14:30:47 GMT

I know there have been several discussions on this topic, but have there been any solutions yet? I just updated to Sequoia yesterday and first my EOS Utility 3 wouldn't open. I followed some threads and downloaded 3.18.5 which opens, but does not see my 5D Mark IV. Are there any work arounds? I use this everyday for work.

Thank you

Steve, have you attempt to remove the application, download a fresh version and do a clean install?

Canon has created a consolidated/updated applications portal. When the page loads it recognizes your OS and loads the appropriate applications. There is also a prompt for your camera model. It's a great page, all the applications located on a single page and very intuitive.

Hi Marc, Thanks for your reply. I did try a clean install and it didn't work. I called Canon and they said that EOS Utility isn't compatible with my OS right now, but will be soon.

I appreciate the help John. I have a Mac studio and it does not have that additional drop down in the security tab, only the Allow Applications from tab.
