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.

What data can I transfer?

Migration Assistant lets you choose the data to move to your Mac. Here’s what moves over for specific apps and data types:

Email, contacts, and calendar information
Email messages, email-account settings, contacts, and appointments move based on which version of Windows you're using and which accounts you have.

Outlook1
Data from 32-bit versions of Outlook in Windows 7 and later move as follows:

  • People move to Contacts2
  • Appointments move to the Calendar app
  • IMAP and Exchange settings and messages move to the Mail app
  • POP settings and messages move to Mail2

Windows Live Mail
Data from Windows Live Mail in Windows 7 and later moves as follows:

  • IMAP settings and messages move to Mail
  • POP settings and messages move to Mail2

Windows Mail
Data from Windows Mail in Windows 7 and later (excluding Windows 8) move as follows:

  • IMAP settings and messages move to Mail
  • POP settings and messages move to Mail2
  • People move to Contacts

Bookmarks
Bookmarks from Internet Explorer, Safari for Windows, and Firefox move to Safari.

System settings
Language and location settings, and custom desktop pictures move to System Preferences. Your web browser homepage moves to Safari preferences.

Migration Assistant transfers your iTunes media as follows: music to the Apple Music app, videos to the Apple TV app, podcasts to the Apple Podcasts app, and audiobooks to the Apple Books app.

Other files
Migration Assistant also moves these files:

Big Data Mac Os X

  • Files from the top-level folder of the currently logged-in user’s home directory
  • Non-system files located in the Windows or Program Files folders
  • Top-level folders located on the Windows system disk and other attached disks

1. Migration Assistant doesn’t support 64-bit versions of Outlook. You can manually migrate Mail, Contacts, or Calendars from Outlook 2013 or Outlook 2016 by signing in and entering the content on your Mac manually.

2. Migration Assistant transfers only the Mail or Contacts data that belongs to the logged-in Windows user. To transfer data from another user account, use Migration Assistant again while you’re logged in to another Windows account. Each time you migrate, your Mac creates a new user account.

We design Mac hardware and software with advanced technologies that work together to run apps more securely, protect your data, and help keep you safe on the web. And with macOS Big Sur available as a free upgrade, it’s easy to get the most secure version of macOS for your Mac.*

Apple M1 chip.
A shared architecture for security.

The Apple M1 chip with built-in Secure Enclave brings the same powerful security capabilities of iPhone to Mac — protecting your login password, automatically encrypting your data, and powering file-level encryption so you stay safe. And the Apple M1 chip keeps macOS secure while it’s running, just as iOS has protected iPhone for years.

Apple helps you keep your Mac secure with software updates.

The best way to keep your Mac secure is to run the latest software. When new updates are available, macOS sends you a notification — or you can opt in to have updates installed automatically when your Mac is not in use. macOS checks for new updates every day and starts applying them in the background, so it’s easier and faster than ever to always have the latest and safest version.

Protection starts at the core.

The technically sophisticated runtime protections in macOS work at the very core of your Mac to keep your system safe from malware. This starts with state-of-the-art antivirus software built in to block and remove malware. Technologies like XD (execute disable), ASLR (address space layout randomization), and SIP (system integrity protection) make it difficult for malware to do harm, and they ensure that processes with root permission cannot change critical system files.

Download apps safely from the Mac App Store. And the internet.

Now apps from both the App Store and the internet can be installed worry-free. App Review makes sure each app in the App Store is reviewed before it’s accepted. Gatekeeper on your Mac ensures that all apps from the internet have already been checked by Apple for known malicious code — before you run them the first time. If there’s ever a problem with an app, Apple can quickly stop new installations and even block the app from launching again.

Stay in control of what data apps can access.

Big Data Master Data Management

Apps need your permission to access files in your Documents, Downloads, and Desktop folders as well as in iCloud Drive and external volumes. And you’ll be prompted before any app can access the camera or mic, capture keyboard activity, or take a photo or video of your screen.

FileVault 2 encrypts your data.

With FileVault 2, your data is safe and secure — even if your Mac falls into the wrong hands. FileVault 2 encrypts the entire drive on your Mac, protecting your data with XTS-AES 128 encryption. Mac computers built on the Apple M1 chip take data protection even further by using dedicated hardware to protect your login password and enabling file-level encryption, which developers can take advantage of — just as on iPhone.

Designed to protect your privacy.

Online privacy isn’t just something you should hope for — it’s something you should expect. That’s why Safari comes with powerful privacy protection technology built in, including Intelligent Tracking Prevention that identifies trackers and helps prevent them from profiling or following you across the web. A new weekly Privacy Report on your start page shows how Safari protects you as you browse over time. Or click the Privacy Report button in your Safari toolbar for an instant snapshot of the cross-site trackers Safari is actively preventing on that web page.

Automatic protections from intruders.

Safari uses iCloud Keychain to securely store your passwords across all your devices. If it ever detects a security concern, Password Monitoring will alert you. Safari also prevents suspicious websites from loading and warns you if they’re detected. And because it runs web pages in separate processes, any harmful code is confined to a single browser tab and can’t crash the whole browser or access your data.

Find your missing Mac with Find My.

The Find My app can help you locate a missing Mac — even if it’s offline or sleeping — by sending out Bluetooth signals that can be detected by nearby Apple devices. These devices then relay the detected location of your Mac to iCloud so you can locate it. It’s all anonymous and encrypted end-to-end so no one — including Apple — knows the identity of any reporting device or the location of your Mac. And it all happens silently using tiny bits of data that piggyback on existing network traffic. So there’s no need to worry about your battery life, your data usage, or your privacy being compromised.

Keep your Mac safe.
Even if it’s in the wrong hands.

All Mac systems built on the Apple M1 chip or with the Apple T2 Security Chip support Activation Lock, just like your iPhone or iPad. So if your Mac is ever misplaced or lost, the only person who can erase and reactivate it is you.
