The best method depends on what you mean by “files.” For a new MacBook and a broad move of supported personal data, use Apple’s Windows Migration Assistant. For a few folders, connect to a Windows shared folder over SMB. An external drive is the most portable fallback, while an existing cloud-sync account is convenient when both computers have reliable internet access.
Migration Assistant copies data without deleting the PC, but it does not turn Windows applications into Mac applications. Whichever method you choose, keep the original files until copies open correctly on the Mac.
Choose the transfer method that fits your move
Decide first whether you are migrating your user data or merely copying selected files. The table below shows the practical differences.
| Method | Best for | What you need | Main limitation |
|---|---|---|---|
| Windows Migration Assistant | A new MacBook or a broad transfer of supported personal data | The matching Windows Migration Assistant version, both computers available, and a compatible network or connection | It transfers supported data, not a guarantee that Windows programs will run on macOS |
| Windows shared folder (SMB) | A few folders or a one-time copy on a trusted local network | File sharing enabled on Windows, reachable computers, and Windows credentials | Permissions, firewall settings, or incompatible filenames can interrupt copying |
| External drive | Large or offline transfers, or a fallback after another method fails | A drive with enough capacity and a connector that fits the MacBook; ExFAT or FAT for cross-platform use | Reformatting erases the drive, and NTFS may be read-only on macOS |
| Cloud sync already in use | Selected files when an account is already configured on the PC and Mac | The same account, available cloud space, and reliable internet | Completion depends on upload and download finishing; current quota and pricing vary by account |
Prepare both computers before copying
A few checks prevent most failed transfers and accidental data loss.

- Close applications that may be changing the files you plan to copy. Do not edit the same documents on both computers during the transfer.
- Check the MacBook’s available storage in Apple menu > System Settings > General > Storage. The destination must have room for the selected data.
- Keep the original PC files untouched until you have opened representative documents, photos, videos, and archives on the Mac.
- Identify the MacBook’s ports before choosing a cable or drive. A USB-A drive or cable may need a USB-C adapter or hub.
- If you are using a network method, place both computers on the same trusted home or office network. Avoid sharing personal folders on an untrusted public network.
Method 1: Use Windows Migration Assistant for a broad move
Migration Assistant is Apple’s purpose-built route for moving supported information from Windows. Apple says it can copy contacts, calendars, email accounts, and other data to appropriate locations on the Mac. It does not erase the Windows PC or replace macOS on the Mac.
What Migration Assistant does—and does not do
The tool is for personal-data migration, not Windows-software migration. Some incompatible applications may not transfer, and a Windows application that does transfer is not thereby made usable on macOS. Plan to install Mac-compatible versions separately and copy the documents those applications created.
Migration Assistant lets you select categories rather than forcing an all-or-nothing copy. Documents and other home-folder files generally go to the corresponding Mac home folder. Photos may be imported into Photos or copied for manual addition. Non-system files from the Windows system disk and other available disks require an administrator login and are placed in a Shared folder.
Use the Windows assistant that matches the Mac’s macOS
Apple’s indexed compatibility article dated October 13, 2026 lists these Windows Migration Assistant builds. Apple can change the table, so check the live Apple instructions immediately before downloading.

| 2.3.1.0 | Windows 7 or later | Big Sur 11 |
| Older builds | As specified for the relevant older Windows release | Earlier macOS releases listed in Apple’s table |
For macOS 13 or earlier, Apple says to put both computers on the same network or connect them directly with Ethernet, as applicable. A Windows PC without Bluetooth Low Energy may prompt you to use a compatible USB Bluetooth adapter; check compatibility before buying one.
Step-by-step Migration Assistant transfer
- Update and close applications. Install available updates on Windows and macOS. Close every application that is open on either computer.
- Remove connection blockers temporarily. If Apple’s connection cannot be established, temporarily disable antivirus, firewall, or VPN settings that may block the transfer. Re-enable each protection as soon as the connection is working or the transfer is complete.
- Prepare proximity and radios. Keep the computers near each other and turn on Wi-Fi and Bluetooth. For older macOS versions, use the same network or an Ethernet connection as required by Apple’s instructions.
- Open Migration Assistant on the Mac. If the MacBook is still in its initial setup, choose the option to transfer from a Windows PC when it appears. If setup is finished, open Migration Assistant from the Utilities folder or find it with Spotlight, then choose From a Windows PC.
- Install and open the matching Windows utility. Download the version that corresponds to the Mac’s macOS, launch it on Windows, and follow its prompts.
- Pair the computers. The Mac displays a code. Enter that code in Migration Assistant on the Windows PC and confirm that the computers are referring to one another.
- Select information. Review the categories and users shown by the assistant. Select the contacts, calendars, email accounts, documents, photos, and other supported data you want to copy.
- Start the transfer. Leave both computers powered and undisturbed until the assistant reports completion. Do not shut down either computer or disconnect a required network cable during this stage.
- Check the results. Sign in to the relevant Mac account, inspect the destination folders and Photos, and open several files from each important category.
Where your data may appear on the Mac
- Home-folder documents and other personal files normally appear in the Mac user’s home folder.
- Imported photos may be available in the Photos app, while some image files may need to be added manually.
- Files copied from the Windows system disk or other disks can require administrator authorization and may be placed in the Mac’s Shared folder.
- Email accounts and calendars may be transferred as account data, but you may still need to authenticate with the service before new messages or events synchronize.
Migration Assistant connection problems
If the Mac and PC do not pair, first confirm that the utility version matches the Mac’s macOS and that both computers meet Apple’s connection prerequisites. On older systems, check the shared network or Ethernet cable. If the PC lacks Bluetooth Low Energy and the utility asks for an adapter, use one known to support that requirement. A firewall, VPN, or security product can also block discovery; change those settings only long enough to test the connection, then restore protection.
Method 2: Copy selected folders through a Windows SMB share
Server Message Block (SMB) sharing is usually the quickest way to move a handful of folders when both computers are on the same local network. It avoids installing a migration utility and lets you choose exactly what to copy.

- Create or identify the folder containing the files you want to move. A dedicated transfer folder makes permissions easier to review.
- Use Windows’ folder-sharing controls to enable sharing for that folder and note the share name.
- Ensure the Windows account you will use has permission to read the folder. If you intend to send files back to Windows, grant write permission only when needed.
- Confirm that network discovery and file sharing are enabled for the trusted network profile, and that the Windows firewall permits file-sharing connections.
- Record the Windows computer name or its local IP address. Keep both computers connected to the same network.
Connect from Finder
- On the MacBook, open Finder.
- Choose Go > Connect to Server.
- Enter a server address such as
smb://computer-name/shareorsmb://IP-address/share, replacing the examples with the Windows computer name or IP address and the share name. - Select Connect, then authenticate with the Windows username and password when prompted.
- Choose the shared folder. It appears as a connected location in Finder, where you can drag files to a Mac folder.
- When finished, eject the connected share from Finder. Leave the Windows originals in place until you have verified the copies.
When SMB is the right choice
Use SMB for selected folders, a local one-time copy, or a transfer that should not consume cloud storage. It is less suitable when the computers cannot share a trusted network, when permissions are controlled by an organization, or when you need a complete migration of account data and settings.

SMB failures and filename restrictions
If Finder cannot see the Windows computer, verify that sharing is enabled, both machines can reach each other, the address is correct, and the Windows credentials have access. Check firewall rules before changing account permissions.
If copying stops on one particular file, inspect its name and the permissions on its parent folder. Windows disallows characters including < > : " / \ | ? *. Rename an offending file or folder on Windows, then retry the copy. Preserve the extension and avoid renaming files while they are open in another application.
Method 3: Transfer with an external drive
An external hard drive, SSD, USB drive, or flash memory card works without a shared network. It is useful for a large offline transfer, a backup before migration, or a fallback when Migration Assistant cannot connect. The drive’s cable must fit the MacBook; an adapter may be required.
Choose a filesystem that both computers can use
For a drive that will be written by both Windows and macOS, Apple’s Disk Utility guidance recommends MS-DOS (FAT) for a disk of 32 GB or less and ExFAT for a disk larger than 32 GB.

| Drive size | Cross-platform format Apple recommends | Practical implication |
|---|---|---|
| 32 GB or less | MS-DOS (FAT) | Readable and writable on Windows and Mac for ordinary transfers |
| Over 32 GB | ExFAT | Suitable for a larger Windows-and-Mac transfer without relying on NTFS write support |
| NTFS | Not a cross-platform write choice on macOS | macOS may read the disk, but Apple says it may not be able to write to it |
Formatting or erasing a disk deletes the files already on it. Before opening Disk Utility or confirming an erase, copy anything important to another location, verify the selected device, and make sure you have chosen the intended filesystem. Do not format a drive merely because it is convenient if it already contains the Windows files you need.
Copy files with the drive
- On Windows, connect the drive and copy the selected files to it. Wait for all copy dialogs and any drive activity to finish.
- Use Windows’ safe-eject control before disconnecting the drive.
- Connect the drive to the MacBook, using an adapter or hub if its connector does not fit.
- Open Finder and select the drive in the sidebar.
- Copy the files into the intended Mac folder, such as Documents, Pictures, or a project folder.
- Eject the drive from Finder after the copy completes.
- Open representative files on the Mac before deleting or repurposing the Windows originals.
Check capacity, connectors, and security
A new portable SSD is optional; Migration Assistant, SMB, or an existing cloud account may be enough. If you choose a drive, confirm its capacity against the actual data size, the connector type for both computers, and whether you need encryption for sensitive files. No transfer-speed figure should be assumed without testing the specific drive, cable, and computers together.

If OneDrive is already configured on the Windows PC, syncing can be convenient for selected folders. It depends on access to the same account, sufficient cloud space, and reliable internet. The available storage and account terms differ, so do not treat this method as a fixed-capacity or fixed-price alternative.

Move files through an existing sync setup
- On Windows, place the files you want to move in the folders selected for OneDrive synchronization, or select the appropriate folders in the OneDrive settings.
- Wait for the OneDrive status indicators to show that the files have finished uploading. Do not shut down the PC while files are still pending.
- On the MacBook, install or open OneDrive and sign in with the same account.
- Choose the folders you want available on the Mac. Files On-Demand or selective-sync settings can keep files online until you open or explicitly download them.
- Wait for the Mac to finish syncing, then open several files locally. A file listed in the cloud is not necessarily fully downloaded to the Mac.
This approach is best for a manageable selection of files that you already keep in the service. It is not a substitute for Migration Assistant when you need local account data such as contacts, calendars, or email settings copied as part of a new-Mac migration.

Verify the transfer before retiring the Windows files
Verification is part of the transfer, not an optional cleanup step. Use a checklist that matches what you moved.
- Open documents from each major folder, including at least one large file and one recently edited file.
- Open photos and videos in the Mac apps you plan to use. Check that dates, orientation, and folder organization are acceptable.
- For archives, extract a copy and confirm that the contents are intact.
- Check filenames that contain unusual punctuation, long paths, or characters that caused an SMB failure.
- For cloud-synced files, confirm that the files are available offline if you need to work without internet access.
- Review the Mac’s free storage after copying. A successful transfer can still leave too little room for macOS updates or applications.
- Keep the Windows PC, original drive, or cloud copy until the Mac files have been checked and backed up.
Troubleshooting by symptom
| Symptom | Likely checks | Action |
|---|---|---|
| Migration Assistant does not connect | Wrong utility version, incompatible macOS/Windows combination, blocked firewall or VPN, missing Bluetooth Low Energy support | Use Apple’s matching version, confirm the required network or Ethernet setup for older macOS, temporarily test without the blocking setting, and use a compatible USB Bluetooth adapter only if prompted |
| The Windows computer is absent in Finder | SMB sharing or network discovery is off, firewall blocks sharing, computers are on different networks, or the address is wrong | Enable sharing for the target folder, confirm reachability and the share address, and check Windows firewall rules for file sharing |
| Finder asks for credentials repeatedly | Incorrect Windows username format or password, or the account lacks permission to the share | Re-enter the Windows account credentials and verify that the account can access the shared folder on Windows |
| Copy stops at one file | Windows-forbidden filename characters or a folder permission problem | Rename the file or parent folder on Windows and confirm read permission, then retry |
| The Mac can read an external disk but cannot save to it | The disk is formatted NTFS or mounted read-only | Copy needed data elsewhere first; use a Windows-and-Mac-compatible FAT or ExFAT disk for future writes, and do not erase the existing disk until its contents are backed up |
| Cloud files appear online but are not usable offline | Sync or download is incomplete, or Files On-Demand left them online-only | Mark the required folders for local availability and wait for the Mac to finish downloading before disconnecting from the internet |
Which method should you use?
You are setting up a new MacBook
Start with Migration Assistant. It can bring over supported contacts, calendars, email accounts, home-folder files, and photos in one guided process. Download the version that matches the Mac’s macOS and keep an external backup or the untouched Windows originals until verification is complete.
You need only a few folders today
Use SMB when both computers are on the same trusted network and you can enable sharing on Windows. It avoids a cloud upload and lets you select individual folders. Use an external drive instead when network permissions are complicated or the computers cannot remain on the same network.
Recommended Free Tools
You have a very large or offline transfer
An ExFAT external drive over 32 GB is the straightforward cross-platform choice under Apple’s format guidance. Confirm the drive’s contents before any erase operation and check that the cable or adapter fits the MacBook.
You already keep the files in cloud storage
Continue with the existing sync service rather than creating a second workflow. Confirm the same account is signed in on the Mac, wait for upload and download completion, and make important files available offline before relying on them away from the internet.
Final safety check
The transfer is complete only when the files open on the Mac and you have a second copy or a verified original. Migration Assistant is the default for supported user-data migration; SMB handles selected folders over a local network; an external drive removes network dependence; and existing cloud sync is convenient for files already organized there. Choose one method, verify the result, and do not delete the Windows originals until the MacBook copy has proved usable.
