I have Mac Sierra 10.13.6 and just upgraded my iPhone 7 to 13.1.2 and Itunes does not recognize my phone.
I understand that if I could upgrade to Mojave, I would not have this problem, but I cannot upgrade as I am user an older computer. Before I upgraded my iPhone last night, I was able to have Itunes recognize my phone once it was plugged, connected to WiFi and connected through a USB port.
I have problem solved with a new Apple charging cable, another computer, and it seems to be something that is going on with my phone and syncing to Itunes.
Help Please! lauree
