Share Mac files with Windows users

To let users connect to your Mac from a Windows computer, turn on file sharing and enable SMB sharing.

Set up file sharing on the Mac

On your Mac, choose Apple menu

> System Preferences, then click Sharing.

Select the File Sharing tickbox, then click Options.

Select “Share files and folders using SMB”.

In the Windows File Sharing list, select the tickbox next to the user account that will be used to share files with Windows users, enter the password for that user, then click OK.

Choose View > Network, select your active connection, then click Advanced.

Click the WINS tab, then enter the workgroup name used by the Windows computer.

If you don’t know the workgroup name, on the Windows computer open Control Panel > System and Security > System. (Windows computers normally use either WORKGROUP or MSHOME.)

Click OK, then click Apply.

Provide the information Windows users need

To connect to your Mac, Windows users need the network address for your Mac, and a username and password to use to log in to your Mac.

To find your Mac computer’s network address, choose Apple menu

> System Preferences, click Sharing, then select File Sharing. The address appears below the “File Sharing: On” indicator, and looks similar to this example: smb://17.212.167.33/.

Create an account on your Mac for each Windows user. To create accounts, choose Apple menu > System Preferences, then click Users & Groups.

If you want to use an account that existed before you installed the latest version of macOS, you may need to reset the password for the account in Users & Groups preferences.

Because the passwords of user accounts used for Windows sharing may be stored in a less secure manner, turn off the account when it’s not being used. Before you turn off Windows sharing, turn off all the accounts you enabled. Otherwise, the passwords are still stored less securely.

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.

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.

Outlook 1
Data from 32-bit versions of Outlook in Windows 7 and later move as follows:

• People move to Contacts 2
• Appointments move to the Calendar app
• IMAP and Exchange settings and messages move to the Mail app
• POP settings and messages move to Mail 2

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 Mail 2

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 Mail 2
• 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.

Pictures
Photos and other images move 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 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:

• 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.

Manage windows on Mac

When you open an app or the Finder on your Mac, a window opens on the desktop. Only one app at a time is active; the name of the app (in bold) and the app menus are shown in the menu bar.

Some apps, such as Safari or Mail, let you open multiple windows or different types of windows at the same time. macOS provides several ways to manage open apps and windows.

Move, align and merge windows

On your Mac, do any of the following:

Move a window: Drag the window by its title bar to where you want it. Some windows can’t be moved.

Align windows: Drag a window close to another one — as the window nears the other one, it aligns without overlapping. You can position multiple windows adjacent to each other.

To make adjacent windows the same size, drag the edge you want to resize — as it nears the edge of the adjacent window, it aligns with the edge and stops.

Merge an app’s windows into one tabbed window: In the app, choose Window > Merge All Windows.

To make a tab a separate window again, select the tab, then choose Window > Move Tab to New Window, or just drag the tab out of the window. See Use tabs in windows.

Maximise or minimise windows

On your Mac, do any of the following in a window:

Maximise a window: Press and hold the Option key while you click the green maximise button in the top-left corner of an app window. To return to the previous window size, Option-click the button again.

You can also double-click an app’s title bar to maximise the window (as long as the option to do so is set to “zoom” in Dock & Menu Bar preferences).

Minimise a window: Click the yellow minimise button in the top-left corner of the window or press Command-M.

You can set an option in Dock & Menu Bar preferences to have a window minimise when you double-click its title bar.

Most windows can be manually resized. Drag the window’s edge (top, bottom, or sides) or double-click an edge to expand that side of the window.

Quickly switch between app windows

On your Mac, do any of the following:

Switch to the previous app: Press Command-Tab.

Scroll through all open apps: Press and hold the Command key, press the Tab key, then press the Left or Right arrow key until you get to the app you want. Release the Command key.

If you change your mind while scrolling through the apps and don’t want to switch apps, press Esc (Escape) or the Full Stop key, then release the Command key.

Close windows

On your Mac, do any of the following:

Close a single window: In a window, click the red Close button in the top-left corner of the window, or press Command-W.

Close all open windows for an app: Press Option-Command-W.

Closing one or all windows for an app does not close or quit the app. To do so, press Command-Q, or click the app’s name in the menu bar, then choose Quit [App]. See Quit apps.

You can hide the active app by pressing Command-H.

Use Mission Control to quickly arrange open windows and spaces in a single layer to easily spot the one you need.
