Hello there, auscgguysgirl.
It seems that you are having issues with syncing your iOS devices after they have been updated to iOS 9. The following Knowledge Base article delves into some great steps for troubleshooting:
iTunes: May become unresponsive when connecting iPhone, iPad, or iPod touch - Apple Support
Start with these initial steps and then proceed through the rest of the document:
Follow the steps below to troubleshoot the issue:
- Install any available software updates for your computer.
- OS X: Use Software Update.
- For Windows: Refer to the documentation for your computer for instructions on using Windows Update to update your computer.
- Update iTunes to the latest version.
- Test with automatic syncing disabled.
- For OS X: Click the iTunes menu and choose Preferences. Click the Devices tab and place a check next to option to "Prevent iPods, iPhones and iPads from syncing automatically." Click OK.
- For Windows: Click the Edit menu and choose Preferences. Click the Devices tab and place a check next to option to "Prevent iPods, iPhones and iPads from syncing automatically." Click OK.
Reconnect your device and test to see if the issue still occurs. If your device is recognized successfully, you may be able to isolate which type of data is causing the issue. Do this by deselecting all syncing options under each of the syncing tabs and then sync. After that, re-enable your sync options one at a time until the issue returns.
If the issue only occurs when syncing data from the Info tab is enabled (For example: Contact, Calendar, Mail account or Bookmark syncing), reset Sync History on OS X or on Windows.
- Check your device for podcasts. If there are any podcasts, manually delete all podcast episodes from the device by sliding your finger across the podcast episode's name and tapping Delete. Once all podcasts are removed from your device, reconnect it to the computer, open iTunes, and test.
- If possible, test to see if connecting your device to a different computer with the latest version of iTunes installed resolves the issue.
- Test with iTunes plug-ins removed.
Thanks for participating in Apple Support Communities.
Kind Regards.
