EOS R7 getting ERR 12 when trying to connect to MacBook Pro (macOS Tahoe 26.5.2). EOS Utility 3

[Trae59]

Hello, I need help with getting my EOS R7 to connect to my MacBook Pro. I get the error message ERR12 or ERR 11. I've tried disconnecting the WiFi and restarting it all over. I've checked and I'm not connected to VPN. Any suggestions on how to get this to work?

Trae59,

It may be that EOS Utlity 3 is not compatible with Tahoe. You'll need to research that.

You could try calling Canon Support at 1-800-OK CANON.

Your version of MacOS was on 6-29-26.  The most current version of the EOS Utility seems to have been released just prior to the Spple update.
