I keep getting this error whenever I try to sync my iPhone on my Macbook. I'm running iTunes 11.4 on OSX 10.9.4. I've tried deauthorizing then reauthorizing. Same issue. I quit iTunes, deleted the SC Info folder, rebooted and reauthorized my MBP. Same issue. I removed SC Info folder again, reinstalled iTunes 11.4, rebooted my MBP, rebooted my iPhone then reauthorized my MBP. Same issue. Stumped here, any suggestions on what to do next? Thanks.
