Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

iTunes could not connect to the iPhone because an invalid response was received from the device.

MacBook Pro Mac OS X Version 10.6.8

iTunes version 11.4

iPhone 5c 32GB iOS version 10.0.2

iPad 2 16GB iOS 9


recognizes/syncs the iPad; DOES NOT recognize iPhone:


"iTunes could not connect to the iPhone “XXXXXXX” because an invalid response was received from the device."

I always select "Trust" on the phone, but iTunes does not recognize my phone.

I have tried the list of suggestions, and nothing has worked.

I have restarted all devices.

Last iPhone sync worked fine, 2 days prior to new iOS download for iPhone.

It likes one but not the other. Is the iPhone iOS the problem?

iPhone 5c, iOS 10.0.2

iOS 10 requires iTunes 12.5.1 or newer which in turn requires OSX 10.9.5 or newer. Software Update only checks for updates for the current system version you are running but that itself may be out of date. It may or may not be possible to upgrade your computer to the required system. Find your computer model on the http://www.everymac.com web site and near the bottom of the system specification section it will say what OS versions it is capable of running. If you cannot run a newer system you will not be able to sync this phone to your present computer. OSX 10.9 and 10.10 are no longer available. Check this article on upgrade options: If your Mac is not Compatible with Sierra but you Have Not Upgraded to El Capitan - https://discussions.apple.com/docs/DOC-10692 El Capitan (OSX 10.11) and Sierra (OSX 10.12) may run slower on older machines and require additional RAM purchase (4 GB is a realistic minimum and many recommend 8GB). Doing a big jump in system versions is also more likely to affect old software.
