Open Windows Migration Assistant, then click Continue. 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. New FileMaker data migration tool Go from days to hours or hours to minutes when importing large data sets. This new time-saving command-line tool helps you update your deployed custom apps in no time.

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, authorise your computer to make iTunes Store purchases. It’s important to authorise this before you sync or play content 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 Windows is up to date. Migration Assistant works with Windows 7 and later.
  • Make sure 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 the migration has finished.

Then use the check disk (chkdsk) utility on your PC to make sure 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 has 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 is not reporting any issues. If the utility can't fix every issue it has found, you may need to get 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 will open automatically 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 display the same passcode that your Mac is displaying.
  9. When both computers display the same passcode, click Continue on your PC and Mac.
  10. Your Mac will scan the drives on your PC to build a list of information to migrate. When the scan has finished, select the information you want to migrate to your Mac and click Continue. Find out about some of the types of data you can transfer.

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

After you've moved your data

When the migration has finished, 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’ll be 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've migrated, authorise your computer for iTunes Store purchases. It’s important to authorise this before you sync or play content downloaded from the iTunes Store.

If you experience any issues when 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 the migration has finished, 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 the migration has finished. 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 copy important data to your Mac manually.

What data can I transfer?

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

Emails, contacts and calendar information
Email messages, email account settings, contacts and appointments are moved 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 are moved as follows:

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

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

  • IMAP settings and messages are moved to Mail
  • POP settings and messages are moved to Mail2

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

  • IMAP settings and messages are moved to Mail
  • POP settings and messages are moved to Mail2
  • People are moved to Contacts

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

System settings
Language and location settings, and custom desktop pictures are moved to System Preferences. Your web browser homepage is moved to Safari preferences.

Pictures
Photos and other images are moved to your home folder. You can then add them to Photos, or open Photos and let it search your Mac for photos to import.

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

Other files
Migration Assistant also moves these files:

Migration Assistant App On Mac Windows 10

  • 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 migrate Mail, Contacts or Calendars from Outlook 2013 or Outlook 2016 manually by signing in and entering the content on your Mac manually.

2. Migration Assistant only transfers 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. Every time you migrate, your Mac creates a new user account.

FileVault

Operating systemmacOS
LicenseProprietary

FileVault is a disk encryption program in Mac OS X 10.3 (2003) and later. It performs on-the-fly encryption with volumes on Mac computers.

Versions and key features[edit]

FileVault was introduced with Mac OS X Panther (10.3),[1] and could only be applied to a user's home directory, not the startup volume. The operating system uses an encrypted sparse disk image (a large single file) to present a volume for the home directory. Mac OS X Leopard and Mac OS X Snow Leopard use more modern sparse bundle disk images[2] which spread the data over 8 MB files (called bands) within a bundle. Apple refers to this original iteration of FileVault as legacy FileVault.[3]

Mac OS X Lion (2011) and newer offer FileVault 2,[3] which is a significant redesign. This encrypts the entire OS X startup volume and typically includes the home directory, abandoning the disk image approach. For this approach to disk encryption, authorised users' information is loaded from a separate non-encrypted boot volume[4] (partition/slice type Apple_Boot).

FileVault[edit]

The original version of FileVault was added in Mac OS X Panther to encrypt a user's home directory.

Master passwords and recovery keys[edit]

When FileVault is enabled the system invites the user to create a master password for the computer. If a user password is forgotten, the master password or recovery key may be used to decrypt the files instead.

Migration[edit]

Migration of FileVault home directories is subject to two limitations:[5]

  • there must be no prior migration to the target computer
  • the target must have no existing user accounts.

If Migration Assistant has already been used or if there are user accounts on the target:

  • before migration, FileVault must be disabled at the source.

If transferring FileVault data from a previous Mac that uses 10.4 using the built-in utility to move data to a new machine, the data continues to be stored in the old sparse image format, and the user must turn FileVault off and then on again to re-encrypt in the new sparse bundle format.

Manual encryption[edit]

Instead of using FileVault to encrypt a user's home directory, using Disk Utility a user can create an encrypted disk image themselves and store any subset of their home directory in there (for example, ~/Documents/private). This encrypted image behaves similar to a FileVault encrypted home directory, but is under the user's maintenance.

Encrypting only a part of a user's home directory might be problematic when applications need access to the encrypted files, which will not be available until the user mounts the encrypted image. This can be mitigated to a certain extent by making symbolic links for these specific files.

Limitations and issues[edit]

Backups[edit]

These limitations apply to versions of Mac OS X prior to v10.7 only.

Without Mac OS X Server, Time Machine will back up a FileVault home directory only while the user is logged out. In such cases, Time Machine is limited to backing up the home directory in its entirety. Using Mac OS X Server as a Time Machine destination, backups of FileVault home directories occur while users are logged in.

Because FileVault restricts the ways in which other users' processes can access the user's content, some third party backup solutions can back up the contents of a user's FileVault home directory only if other parts of the computer (including other users' home directories) are excluded.[6][7]

Issues[edit]

Several shortcomings were identified in Legacy FileVault. Its security can be broken by cracking either 1024-bit RSA or 3DES-EDE.

Migration Assistant App On Mac Shortcut

Legacy FileVault used the CBC mode of operation (see disk encryption theory); FileVault 2 uses stronger XTS-AESW mode. Another issue is storage of keys in the macOS 'safe sleep' mode.[8] A study published in 2008 found data remanence in dynamic random-access memory (DRAM), with data retention of seconds to minutes at room temperature and much longer times when memory chips were cooled to low temperature. The study authors were able to use a cold boot attack to recover cryptographic keys for several popular disk encryption systems, including FileVault, by taking advantage of redundancy in the way keys are stored after they have been expanded for efficient use, such as in key scheduling. The authors recommend that computers be powered down, rather than be left in a 'sleep' state, when not in physical control by the owner.[9]

Migration Assistant App On Mac

Early versions of FileVault automatically stored the user's passphrase in the system keychain, requiring the user to notice and manually disable this security hole.

In 2006, following a talk at the 23rd Chaos Communication Congress titled Unlocking FileVault: An Analysis of Apple's Encrypted Disk Storage System, Jacob Appelbaum & Ralf-Philipp Weinmann released VileFault which decrypts encrypted Mac OS X disk image files.[10]

A free space wipe using Disk Utility left a large portion of previously deleted file remnants intact. Similarly, FileVault compact operations only wiped small parts of previously deleted data.[11]

FileVault 2[edit]

Security[edit]

FileVault uses the user's login password as the encryption pass phrase. It uses the XTS-AES mode of AES with 128 bit blocks and a 256 bit key to encrypt the disk, as recommended by NIST.[12][13] Only unlock-enabled users can start or unlock the drive. Once unlocked, other users may also use the computer until it is shut down.[3]

Performance[edit]

The I/O performance penalty for using FileVault 2 was found to be in the order of around 3% when using CPUs with the AES instruction set, such as the Intel Core i, and OS X 10.10.3.[14] Performance deterioration will be larger for CPUs without this instruction set, such as older Core CPUs.

Master passwords and recovery keys[edit]

When FileVault 2 is enabled while the system is running, the system creates and displays a recovery key for the computer, and optionally offers the user to store the key with Apple. The 120 bit recovery key is encoded with all letters and numbers 1 through 9, and read from /dev/random, and therefore relies on the security of the PRNG used in macOS. During a cryptanalysis in 2012, this mechanism was found safe.[15]

Changing the recovery key is not possible without re-encrypting the File Vault volume.[3]

Validation[edit]

Users who use FileVault 2 in OS X 10.9 and above can validate their key correctly works after encryption by running sudo fdesetup validaterecovery in Terminal after encryption has finished. The key must be in form xxxx-xxxx-xxxx-xxxx-xxxx-xxxx and will return true if correct.[16]

Starting the OS with FileVault 2 without a user account[edit]

If a volume to be used for startup is erased and encrypted before clean installation of OS X 10.7.4 or 10.8:

  • there is a password for the volume
  • the clean system will immediately behave as if FileVault was enabled after installation
  • there is no recovery key, no option to store the key with Apple (but the system will behave as if a key was created)
  • when the computer is started, Disk Password will appear at the EfiLoginUI – this may be used to unlock the volume and start the system
  • the running system will present the traditional login window.

Apple describes this type of approach as Disk Password—based DEK.[12]
