Environment: iPhone 4s 6.1.2 Mac Mini 10.8.3 Macbook Air 10.8.2 When I connect my iPhone to my Mini I get the error from the title. 1. It only happens on one machine (my main mac mini). On my Air it works ok, and on my work Windows machine also OK 2. Happened only after I updated to 6.1.1 3. iPhone is visible to iTunes only if in DFU mode 4. I've done the iTunes troubleshooting 5. I've completely removed iTunes with CleanMyMac and reinstalled 6. I've connected the phone with a different cable and to a different USB 7. I've restarted both my mac and hard restarted the iPhone 8. I've setup a clean iOS with no restore from backup Nothing helps.... So.... Help?!
