Move your data from a Windows PC to your Mac

Use Windows Migration Assistant to transfer your pictures, documents, and other data from a Windows PC to your Mac.

Windows Migration Assistant transfers your contacts, calendars, email accounts, and more from a PC. It migrates this data to the appropriate places on your Mac. After migrating data to your Mac, authorize your computer for iTunes Store purchases. It’s important to authorize before you sync or play content that you download from the iTunes Store.

If you’re migrating from one Mac to another Mac, follow the steps to move your content to a new Mac.

Before you begin

To prepare for a smooth migration:

• Make sure that Windows is up to date. Migration Assistant works with Windows 7 and later.
• Make sure that you know the name and password of an administrator account on your PC.
• Connect your Mac and PC to the same network, such as your home Wi-Fi network. Or connect an Ethernet cable between the ports on your Mac and PC to create a direct network connection. Some Mac models require an Ethernet adapter, such as the Belkin USB-C to Gigabit Ethernet Adapter or Apple Thunderbolt to Gigabit Ethernet Adapter.
• If you’re using Microsoft OneDrive on your PC, follow Microsoft’s instructions for uninstalling OneDrive before continuing. You can reinstall OneDrive after migration is complete.

Then use the check disk (chkdsk) utility on your PC to make sure that your Windows hard drive doesn’t have any issues:

1. Right-click the Start button, then click Run.
2. Type cmd and press Enter. Command Prompt opens.
3. At the prompt, type chkdsk and press Enter.
4. If the utility reports that it found problems, type the following, where drive is the letter that represents your Windows startup disk, such as D:
5. Press Enter.
6. At the prompt, type Y , then restart your PC.
7. Repeat this process until the check disk utility reports no issues. If the utility can’t fix every issue that it finds, you might need to have your PC serviced. Then migrate your data to your Mac.

Move your data

This section guides you through migration, post-migration, and what to do if the steps don’t work for you.

How to move your information from a PC to your Mac

1. On your PC, download and install the appropriate Windows Migration Assistant, based on the version of macOS on your Mac:
   • Windows Migration Assistant for macOS Big Sur
   • Windows Migration Assistant for macOS Mojave and macOS Catalina
   • Windows Migration Assistant for macOS Sierra and High Sierra
   • Windows Migration Assistant for OS X El Capitan or earlier
2. Quit any open Windows apps.
3. Open Windows Migration Assistant, then click Continue.
   
4. Start up your Mac. Setup Assistant automatically opens the first time you turn on your Mac. If you’ve already set up your Mac, open Migration Assistant, which is in the Utilities folder of your Applications folder.
5. On your Mac, follow the onscreen prompts until you get to the migration pane of the assistant. Select the option to transfer your information “From a Windows PC,” then click Continue.
   
6. When prompted, enter an administrator name and password.
7. Click Continue to close any other open apps.
8. In the migration window on your Mac, select your PC from the list of available computers. Then wait for the PC to show the same passcode that your Mac shows.
9. When both computers display the same passcode, click Continue on your PC and Mac.
10. Your Mac scans the drives on your PC to build a list of information to migrate. When the scan completes, select the information that you want to migrate to your Mac and click Continue. Learn about some of the data that you can transfer.
    

You can watch the progress and estimated time remaining on both the PC and your Mac. They tell you when migration is complete.

After you move your data

When migration completes, close Windows Migration Assistant on your PC. Then log in to the new user account on your Mac. The first time you log in to a user account migrated from your PC, you’re asked to set a password. You can use the same password that you used on your PC, or create a new password.

After logging in to the user account that you migrated, authorize your computer for iTunes Store purchases. It’s important to authorize before you sync or play content downloaded from the iTunes Store.

If you have issues moving your data

• Quit all open apps on your PC, then try migrating your content again. For example, you can press Alt-Tab to choose an open application, then press Alt-F4 to quit it.
• If your PC doesn’t appear in the Setup Assistant or Migration Assistant window on your Mac, make sure the computers are connected to the same network. You can create a network by connecting a single Ethernet cable between your Mac and PC. If that doesn’t help, check for firewall software on your PC and turn it off. After migration completes, you can turn firewall software on again.
• If Migration Assistant doesn’t open on your PC, turn off any antivirus software on your PC. Then try to open Migration Assistant again. After migration completes. You can turn that software on again.
• If you still can’t migrate your information successfully, you can use an external drive or file sharing to manually copy important data to your Mac.

Moving to a new Mac? Before taking these steps, you can use Migration Assistant to move your files from the old Mac to your new Mac.

Learn more about deauthorizing computers used with your iTunes account.

Sign out of iCloud

Sign out of iMessage

Reset NVRAM

Shut down your Mac, then turn it on and immediately press and hold these four keys together: Option, Command, P, and R. Release the keys after about 20 seconds. This clears user settings from memory and restores certain security features that might have been altered.

Optional: Unpair Bluetooth devices that you’re keeping

If your Mac is paired with a Bluetooth keyboard, mouse, trackpad, or other Bluetooth device that you plan to keep, you can unpair it. This optional step prevents accidental input when the Mac and device have separate owners but remain in Bluetooth range of each other.

If you’re unpairing Bluetooth input devices from a desktop computer such as an iMac, Mac mini, or Mac Pro, you must plug in a USB keyboard and mouse to complete the remaining steps in this article.

To unpair a Bluetooth device, choose Apple menu  > System Preferences, then click Bluetooth. Move your pointer over the device that you want to unpair, then click the remove (x) button next to the device name.

Erase your hard drive and reinstall macOS

The best way to restore your Mac to factory settings is to erase your hard drive and reinstall macOS.

After macOS installation is complete, the Mac restarts to a setup assistant that asks you to choose a country or region. To leave the Mac in an out-of-box state, don’t continue setup. Instead, press Command-Q to shut down the Mac. When the new owner turns on the Mac, the setup assistant guides them through the setup process.
