What is a "Session ID" and why's it missing?

Ever since 2 iOS updates ago... I haven't been able to update my iPhone 5c. When I try to update it I get this error message:


"iTunes could not connect to this iPhone. The session ID is missing."


I saw no previous issues like this... anyone know what's going on?

Mac Pro, OS X Yosemite (10.10.1), Logic X, 8 TB of external OWC HD's

Hey Andy,


I see from your post that you're getting an error message when you plug your iPhone into your Mac that says, "iTunes could not connect to this iPhone. The session ID is missing." To start troubleshooting this issue I'd like you to please try the options below.


  • Use a different USB cable
  • Try a different USB port (or plug directly into the Mac if you are using a USB hub)


If the issue persists please let us know.


Take care.
