Can't Update R5 firmware to 2.10

[kmonroe99]

R5, USA, current firmware is 1.5.0, trying to update to 2.1; Mac OS Sequoia 15.4.1.  When using EOS Utility 3 with USB connection, the utility software and camera talk to each other but I get the message "The selected file is not the appropriate updater for this camera. " when trying to update.  If I try to update straight from freshly formatted card, I get "Update file cannot be found..." and I have to remove battery to be able to use the camera.

I have been told that it doesn’t matter which Canon site you download from, but I have seen examples in these forums where it made the difference.

One thing that has not been mentioned yet is to have only one card in the camera during updates.
