What Causes the iTunes Error 4005?

There are a few potential causes of the iTunes error 4005:

  • Outdated version of iTunes – If you haven’t updated iTunes recently, an outdated version could be causing sync and restore issues.

How to Fix iTunes Error 4005

If you encounter iTunes error 4005, try the following troubleshooting steps:

  1. Update to the latest version of iTunes – Go to Help > Check for Updates or download the newest version from Apple’s website.

  3. Restart your computer and device – A simple restart can clear out minor glitches causing error 4005.
  4. Try a different USB cable and USB port if possible – Cable issues are a common cause of sync problems.
  5. Disable WiFi/VPN connections – Connect your computer directly to the internet via ethernet if possible when syncing/restoring.

  7. Check Apple’s System Status page – Verify there are no outages with Apple services or the iTunes Store.
  8. Reset permissions on the iTunes library folder – Go to Get Info > Sharing & Permissions on the iTunes folder and make sure you have Read & Write access.

Fixing Corrupt iTunes Library

One of the most common causes of error 4005 is a corrupted iTunes library. If other basic troubleshooting steps don’t resolve the problem, you may need to recreate your iTunes library. Follow these steps:

  1. Exit iTunes if open.
  2. Hold Shift + Option (Mac) or Shift + Ctrl (Windows) and launch iTunes. This will open a dialog asking if you want to create a new library or choose a different library.
  3. Click Create Library and choose a new folder location to store your new iTunes library.
  4. Import your media files back into the new library, making sure to leave out any corrupt or problematic files.
  5. Sync your device with the new, clean iTunes library.
