User level: Level 1 (17 points)When attempting to update my iPhone 15 + to 26.7, using iTunes on a MacPro (Mid 2010) running Mojave 10.14.6. Update fails! Says I need a software update before iTunes can update the iPhone but the software download never completes. Says it can’t connect to the update server?? iTunes in Mojave has always updated my iPhone 15 Plus and my iPad Pro.
Any ideas or help would be greatly appreciated!

Hi there
Please try this
The easiest way to bypass iTunes server connection errors is to let the iPhone handle the update itself:

Dear WheelieNick,
Thank you for your response. I’m aware you can do “Over the air” updates however, it is my understanding that they are “Incremental updates” downloading only the code that has changed. Using iTunes or using Finder with later OS’s download the complete code contained in the OS update. I’ve always believed a “Complete” update is hopefully more reliable and less error prone because that is what the Apple developers test on. I might be wrong, but I believe this to be true.
Sincerely,
Dave Hill
