You'll see a notification if your device is already up to date. This will download the update to your computer, and apply it to your iOS device. This process may take a while, and you can monitor the progress of the update on your device's screen. After the update has been installed on your iPhone, iPad, or iPod, you'll need to complete it by entering your passcode or signing in with your Apple ID. If you installed a major update, you may be given a brief overview of the changes.
