Here we are answering the question, “why won’t my iPhone sync to my iTunes” precisely. Along with being the solutions, these tips are also the cause of the error. So, make sure that you resolve all of them.

Tip 1. Update iTunes to Date

The first thing to check when the iPhone won't sync to iTunes is the iTunes pending update. If there is a pending software update, then it is evident that you will face problems during sync. So, get rid of the older version of iTunes, and the issue will be resolved.

If you have a mac:

If your mac is running on macOS(Catalina), you can update iTunes from the Apple Music app, Apple TV app, Apple Books app and Apple Podacasts app.

Once you failed to update the latest version of macOS, you can:

  • Go to "App Store" on Mac.
  • Tap "Updates" at the top of this window.
  • Check if there is iTunes update, then press "Install".

If you have a PC:

If you have iTunes installed from the Microsoft Store.

  • When a new version released, iTunes from the Microsoft Store would update automatically.
  • You can also check for updates from Microsoft Store.

If you have iTunes installed from Apple's website.

  • Double click iTunes.
  • Select "Help" > "Check for Updates" at the top menu bar.
  • Follow the onscreen steps to install the latest version.

Tip 2. Check USB Lightning Cablee

In case there is a fault in the USB lightning cable that you are using, you will abruptly face the iPhone won't sync to computer issue. Make sure that the cable you are using is working fine and dust-free. Also, keep in mind that you must use the original cable designed by Apple for connection. If the wire is fine and you are still facing the sync issue, then move on to the next fix.

Tip 3. Try a Different USB Port

When the iPhone doesn't sync photos, check if the USB port is working fine or not. There are multiple USB ports on every system. So, if one port is causing issues, then you should try using a different port. This will ensure that the problem isn’t caused by iTunes.

Tip 4. Update your Firewall Settings

If the iPhone still won’t sync with iTunes, then chances are there that the system firewall is blocking iTunes operations. This firewall software program has the Security function, which prevents harmful operations. But sometimes, the Firewall also blocks iTunes from working correctly. This fix is typically for the Windows system, but you can also use it on Mac systems.

  1. 1. Open the Control Panel and select the System & Security option. Pick the Windows Firewall option and review the list of apps that can communicate through firewalls.
  2. 2. Make sure that the box in front of iTunes is checked, which means iTunes can operate without interruption of the Firewall software. Click on the “Ok” button to apply the changes, and now you can sync the device with iTunes.

Tip 5. Reauthorize iTunes

A major reason why the iPhone does not sync music to iTunes is a security concern that halts the sync session every time you try it. To fix this, you need to reauthorize your system with iTunes.

Step 1: Launch iTunes on your system and go to the Account tab. You will see the option that states “Authorizations.” Select the “Authorize This Computer” option and save changes.

When you have the authorization, the option won’t be highlighted. But when the option is highlighted, it means that you need to reauthorize your computer. Click on the option and wait for iTunes to finish the operation.

Tip 6. Restart your Computer

As a simple fix when the iPhone won’t sync to a computer, restarting it will be the easiest fix. It is essential that you restart your computer to implement the changes you recently made to the system.

Tip 7. Restart your iPhone

A simple restart is a soft fix for issues when the iPhone won't sync with the computer. If the problem is with the iOS device, not the system or iTunes, a simple restart is likely to resolve the issue. Fortunately, to restart the iPhone models, there is a common method.

For iPhone 8 or above:

Tip 8. Try Another Sync Method: Wi-Fi or USB

Just imagine that it is your Fitbit that won't sync with the iPhone, then switching the method of sync might be the answer to your problems. Fortunately, iTunes can sync with the connected device using USB cable and Wi-Fi. So, in case the USB is not working, you can turn on the Wi-Fi sync option.

Open iTunes and go to the Summary tab. In the Options tab, you will see the “Sync with this iPod over Wi-Fi” option.

enable wifi sync

Tick the option and try syncing the device. Hopefully, it will resolve the problem, and you will be able to sync your iDevice with iTunes seamlessly.

When the iPhone won't sync over Wi-Fi, this means that there is a problem with the drivers. Whenever you connect your device with a computer, it installs a driver that allows the devices to communicate with each other. So, when there is a problem in the connection that you can’t understand, then updating the drivers seem like an ideal solution.

  1. 1. Open the Device Manager on your Windows system and select your device name.
  2. 2. Right-click on the name and open Properties window. Switch to the Driver window, and you will see if there is an update required for the drivers installed.
