If your iOS 12 device isn't recognized by iTunes, you might need to upgrade macOS or iTunes

iTunes might not respond, might not recognize your device, or you might see a message that says "iTunes could not connect to this [device]. You do not have permission." when you try to connect an iPhone, iPad, or iPod touch with iOS 12 installed.

Update your Mac to the latest version of macOS and to the latest version of iTunes. If iTunes still doesn't recognize your device, follow the steps below to upgrade to iTunes 12.8 on your Mac.

iPhone XS and iPhone XS Max require a Mac running at least OS X El Capitan 10.11.6 or later and iTunes 12.8 or later to sync and back up with iTunes.

To upgrade iTunes, use these steps:

  1. If it's open, quit iTunes.
  2. If your iOS device is connected to your Mac using USB, disconnect the cord.
  3. Download iTunes 12.8 from Apple and install it on your Mac.
  4. Unlock your iOS device, and while the home screen is visible, reconnect it to your Mac using USB.
  5. Open iTunes.
  6. When you see a message that says "A software update is required to connect to this [device]," click Install. Learn more about what to do when you see this message.
