Canon cameras not connecting to EOS Utility 3 with a cable

Hi Maw2122,

This is the reply I received from Canon.

Thank you for your request and for contacting Canon.

We are sorry to hear that you are experiencing some issues with Canon EOS Utility

We would like to inform you that macOS 10.15.2 was released by Apple on December 11, 2019. Following operation checks performed with this version at Canon, we have confirmed a USB connection issue with “EOS Utility 3.11.1 for Mac OS X” and "Picture Style File Registration Tool 1.0.0 for Mac OS X" whereby the functions enabled by connecting a camera and a Mac device via USB cannot be used.

This issue does not occur on macOS 10.15.0/10.15.1.

We are currently preparing to release versions of these applications that incorporate a fix for this issue.

We sincerely apologise for the inconvenience and appreciate your patience on this matter.

Thank you again for contacting Canon Customer Service and we remain under your disposal for any additional questions or requests.

We wish you a nice day.

This is helpful, so it seems that Canon are looking into it

Mike.

HI I_rina,

Thanks for your reply, my software is up to date and I think it is a problem with OS 10.15.2 as it was ok in previous updates.

I have contacted Canon and they have come to the same conclusion and are looking into the situation and a possible update.

Regards, Mike.
