Message "Can't download the software because of a netwok problem” after iPhone updated to 17.1.1

There is a tiny little upgrade that needs to be installed after certain iPhone updates, to allow connection of the phone. Sometimes it goes off the rails and refuses to install, or never says it has finished, and other wonky results. Restart your Mac and try again another time. When you plug in your phone, you may see that notification again, and you can try again.

If successful, it typically completes in under two minutes, and does not appear to change anything, but now your phone will be recognized and you can complete you business.

perhaps some software you added or an especially convoluted network setup or a VPN you installed yourself is interfering.

restart in Safe mode and try the upgrade form there.

To determine whether added software is the problem, run in Safe Mode, where no third-party items are loaded.

"Works in Safe Mode, Fails in regular mode" implies, "it's something you added."

Start up your Mac in safe mode - Apple Support

"Unable to run update : When I plug in my iPhone, I'm prompted to update before phone can be recognized. When I attempt to run the update, I get 'Can't download the softweare because of a netwok problem;. This was not a problem before the iPhone updated to 17.1.1 I'm on a Mac Pro (mid 2012) running High Sierra 10.13.6. I have Xfinity cable."
