My Xs quit working, so I purchased an 11 Pro today. My iMac is on Catalina. The iPhone showed up in Finder, and I began the Restore process by accepting the Terms and Conditions, however each time I accepted and hit continue, to start the actual restore process, the iPhone would immediately disappear from Finder with no warning and the Restore wouldn't happen. Happened over and over.
I found, after a quick search, there are plenty of others who had the same issue. For anyone else having the issue, force the phone to be set up as a new phone first, that will update the software, and then do the Restore. It's the only way to get it to work (for me) and there is zero warning or instruction telling the user to do that first.
