iTunes can't connect to iPad since upgrade 10.0.1
I have an iPad air2, recently upgraded to 10.0.1.
My computer is iMac, Mac OS X version 10.7.5
Since the upgrade, when I try to sync, I get the following message:
"iTunes could not connect to the iPad "iPad" because an invalid response was received from the device"
Exactly the same has happened with my iPhone5.
Am I missing a trick?
