The message says it all. You can't use EOSU with that Mac OS. That is a Mac problem, not a Canon one. Check and see if Canon has updated the utility since the older 5D Mk III was released..

Hello Janeyjo,

With regards to the EOS 5D Mark III's connection to your Mac, you will want to be running EOS Utility 3.7.0. This can be downloaded for Sierra from the main Download Library, here. Once downloaded and installed your EOS 5D Mark III shouldn't encounter an error when connecting to Windows.

EOS Utility works fine with Sierra... just make sure you visit the support page and download the appropriate version.

I use a Mac and have had no trouble using the 5D III (or 5D IV) with any of the OS versions.

Visit this page: https://www.usa.canon.com/internet/portal/us/home/support/details/cameras/dslr/eos-5d-mark-iii?tab=drivers

In the “Drivers & Downloads” section make sure you select “Software”

Make sure you set the OS version to “macOS Sierra v10.12”

That will update the page to show all the available downloads. The latest version of EOS Utility (you’ll see a few) is v3.7.0.

You probably want to grab the latest version of EOS Utility and the latest version of Digital Photo Professional. Drag any older versions from your Mac’s “Applications” folder to the trash.
