"Itunes can not connect to this iphone. Could not send a message to the device."
I have an Iphone 7 and my Itunes account on my 2012 Macbook Pro will not detect my iphone. I have updated the software on my phone and laptop to the latest versions and still it will not register. When i connect my iphone its will say 'trust computer' amd i will select 'trust' but then iphoto will appear and say "unlock iphone" when it is unlocked and itunes will have a pop up message saying "Itunes can not connect to this iphone. Could not send a message to the device."
I have tried resetting network settings and i use a proper Apple usb cable, nothing seems to work. Please help i'ce had this issue for a year, i just want music on my phone.
