How to Sync iPhone to New Computer without Erasing in 3 Ways

...

iTunes allows you to back up your iPhone, iPad, or iPod to your computer. However, if you try to sync your iPhone with a new computer, things can get tricky. First, the new computer needs to be authorized. Then, when you try to sync your iPhone, iTunes warns you that doing so may erase the media files on your device. When you restore a backup from iTunes, you'll see another warning: All data on your iPhone will be replaced with what's on your new computer.

To keep your iPhone in sync with the new Windows and Mac based computer without losing data, many users choose to use third-party tools to back up or transfer their iPhone data. In this article, we'll show you two reliable ways to sync your iPhone with a new computer - without erasing your data.

Part 1: Sync iPhone to New Computer with iTunes

Worried about iTunes wiping your data during a sync? You're not alone. To keep your current data safe, make sure to turn off automatic syncing in iTunes first. Once that's done, you can sync your iPhone manually. Here's how:

Step 1: Open the latest version of iTunes on your computer.

Step 2: Click on the "Edit" menu and choose "Preferences."

Step 3: Go to the "Devices" tab and check the option that says "Prevent iPods, iPhones, and iPads from syncing automatically." Click "OK."

Step 4: Now plug your iPhone into your computer. In iTunes, right-click your device name under the "Devices" section. Choose "Transfer Purchases" to save your content, or click "Sync" to begin syncing manually.

Cons of using iTunes for syncing:

  • You can't preview files before syncing.
  • iTunes only supports syncing certain types of data, mainly media.
  • It's known to crash or freeze during the process. (iTunes Keeps Crashing?)

Part 2: Sync iPhone to New Computer via Finder

If you're using macOS Catalina or later, iTunes has been replaced by Finder for syncing your iPhone. Here's how you can safely sync your iPhone to a new Mac without losing anything:

Step 1: Disable Auto Sync

  1. Connect your iPhone to the new Mac using a USB cable.
  2. Open Finder from the Dock or Applications folder.
  3. Select your iPhone under the "Locations" section in the left sidebar.
  4. In the General tab, scroll down and uncheck the box next to "Automatically sync when this iPhone is connected."

Step 2: Trust the Device

  1. If prompted, click "Trust" on the Mac and tap "Trust" on your iPhone.
  2. Enter your iPhone passcode to confirm.

Step 3: Back Up or Sync Manually

  1. You can now choose to manually "Back Up Now" or manage data like music, movies, and files without auto-sync erasing anything.
  2. To avoid overwriting, don't select any sync options that might conflict with your iPhone's current content unless you're sure.

Cons of using Finder for syncing:

  • Limited data types can be synced (mainly media).
  • No option to preview files before syncing.
  • May overwrite existing data if not careful.
  • Manual sync process can be confusing for beginners.
