Hello. I have the same problem. I bought an iPhone 14 Pro, it came with iOS 16.7.1. I have a MBP 2011 latest series, iTunes DOES NOT recognize the phone! The same software notice appeared and ends by saying that this software is no longer available!!
In other words, Apple cut off communication between my Mac and the new phone WITHOUT prior notice! I have been punished for my purchase!... (I had iPhone 5; 5S; 2 x SE; 3 iPods; 1 iPad, and now the extraordinary 14Pro..., I consider myself an excellent customer and admirer of the Apple brand).
I can't even imagine updating to iOS 17!!, I'm sorry because I'm interested in the update to the camera, very important!
Something incredible!!, I have a PC at work with two OS: Windows 7 and Windows 10. In both operations I use iTunes.
iTunes on Windows 7 (2009 - older than EL Capitan!!!), PERFECTLY recognizes my 14Pro with 16.7.1!!!!.
Gentlemen of Apple, please, as loyal customers we need an URGENT solution to this problem! Our computers are MAC, your computers!! and NOT PC!!!.
