After updating by iPad2 to IOS 7, which wroked, I came home and then updated itunes to 11.1 before attempting a sync over USB. The sync goes through a backjup, and mail sync and son on until it reaches the syncing of apps. At that point iTunes stops the update with the error code -50 and the entire sync fails.

 

Has anyone encountered this? Any fixes?

 

Thanks in advance!

    According to this article:

    iTunes: Specific update-and-restore error messages and advanced troubleshooting

    http://support.apple.com/kb/TS3694#error50

    Error 13, 14, 35 and 50 (or -50)

    These errors are typically resolved by performing one or more of the steps listed below:

    1. Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting.
    2. Put a USB 2.0 hub between the device and the computer.
    3. Try a different Dock Connector or Lightning Connector to USB cable.
    4. Eliminate third-party security software conflicts.
    5. There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. An incorrectly set default packet size can cause this error. Contact the software manufacturer that installed the packet-size modification for assistance. Or, follow this article by Microsoft to reset the packet size back to the default for Windows:How to reset Internet Protocol (TCP/IP).
    6. Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online.
    7. Try to restore from another known-good computer and network.

    The iPad is connected directly to my Quad Core iMac, I have tried all of the ports and there is no difference to the issue.

     

    Attempting to use a hub results in the same problem.

     

    Different Doc Connector cable results in the same problem.

     

    Restarted iMac will no third party programs running, no change in problem.

     

    Connect to internet directly, no hub, same fault.

     

    Try to restore from my MacBook Pro, same fault.

     

     

    Any other ideas? Thank you for the thoughts!

    Me again....

     

    So, updated to the new iTunes 11.1.1 and this problem still continues. Cannot sync at all with my iPad. Oh some of the problems with 11 are fixed, and thank you for that, but the #1 problem is still there.

     

    Any new ideas?
