iPhone 6s not connecting to iTunes after updating MacBook Pro
Yesterday I updated iTunes on my MacBook Pro to the latest version... version 12.8.
I also updated my iPhone 6s to the latest version... iOS 12.0 and I was no longer able to connect my iPhone to iTunes on my MacBook Pro. iTunes gave me a message saying 'To use your iPhone with iTunes, you need to install OS X 10.11.4 (or later)'.
So.... Today I updated my MacBook Pro to macOS High Sierra Version 10.13.4 and I am still unable to connect my iPhone to iTunes. iTunes doesn't come up when I plug my iPhone into the USB and it doesn't give me any error messages... my phone just doesn't show up in iTunes anymore.
I have tried restarting both my computer and phone, tried different USB cables, tried both USB ports and nothing seems to work.
I have a...
MacBook Pro
13-inch, Late 2011
I just received my iPhone Xs in the mail, so I am wondering... if I already backed up my iPhone 6s in iTunes before all the updating, will my iPhone Xs connect to iTunes or do I first need to figure out the problem as to why my iPhone 6s won't connect to iTunes?
Thanks in advance!
MacBook Pro, macOS High Sierra (10.13.4)
