The safest way to move your documents, applications, user accounts, and settings from an old Mac to a new MacBook is Apple’s built-in Migration Assistant. It can transfer directly between the two Macs or restore from a Time Machine backup. You can run it during the new Mac’s first-time setup or later, and it does not erase the old Mac or replace macOS on the new one.
For most people, use a direct Mac-to-Mac transfer when both computers are available and working. Use a Time Machine backup when you already have a current backup, the old Mac is unavailable, or you want a separate recovery copy. Neither method requires buying a cable in the normal case.
Choose the right migration method
Migration Assistant moves the contents that Apple supports—documents, applications, user accounts, and settings—without turning the process into a manual file-by-file copy. Decide which source is practical before you begin.

Prepare both Macs before moving anything
Install available macOS updates
Update both computers before opening Migration Assistant. Apple’s instruction is explicit: “Make sure macOS is up to date on each Mac.” Updates can improve compatibility and reduce avoidable setup failures. The Macs do not have to run the same macOS version, so do not delay a transfer solely because the versions differ.
Connect power and arrange the computers
Plug both MacBooks into power. Keep them close together with Wi-Fi enabled if you are transferring wirelessly. Avoid moving either computer or closing its lid during the transfer. A direct transfer can still be attempted when Wi-Fi is unavailable only if your chosen, model-specific wired procedure supports it; do not buy hardware before checking the models and ports.
Temporarily disable software that can interrupt the connection
Apple advises turning off antivirus software, third-party firewalls, and VPN software until migration is complete. These programs can block discovery or communication between the Macs. Re-enable them after you have verified the new Mac.
Decide whether you also need a backup
A direct transfer does not create a backup by itself. If the old Mac contains irreplaceable material, make or confirm a Time Machine backup before starting, even if you plan to transfer directly. An external hard drive for Mac Time Machine backup is optional equipment for that purpose, not a requirement for direct Mac-to-Mac migration.
Keep account and application details available
Have passwords, two-factor authentication devices, recovery keys, and software subscription details nearby. Migration Assistant can move an application and its files, but it cannot guarantee that every license, sign-in session, cloud connection, or activation state will continue working on a different Mac.

Directly transfer from the old Mac
The new Mac initiates the connection, while the old Mac authorizes sending its information. The labels can vary slightly by macOS release, so follow the wording displayed on your screens.
Start Migration Assistant on the new Mac during first-time setup
- Turn on the new MacBook and work through Setup Assistant until it asks whether you want to transfer information.
- Choose From a Mac, Time Machine or startup disk (or the equivalent wording shown on your version).
- Leave the new Mac at the transfer screen while you prepare the old Mac.
Start Migration Assistant on the old Mac
- Open Migration Assistant on the old Mac. During normal use, you can find it in the Utilities folder or by searching with Spotlight.
- Choose the option to transfer information To another Mac.
- Follow the prompts that allow the old Mac to be discovered by the new one.
Confirm the Mac and security code
- On the new Mac, select the old Mac when it appears as an available source.
- If a security code appears on either computer, compare both screens carefully.
- Continue only when the codes match. If they do not, cancel and restart the connection rather than authorizing an unknown device.
Select what to transfer
Migration Assistant displays categories such as user accounts, applications, files and folders, and computer or network settings. Select the categories you need, review the storage calculation, and start the transfer. You can migrate the account and files you use every day without assuming that every system setting or application credential will be portable.
The old Mac remains intact. Migration Assistant copies supported information; it does not delete the source Mac or replace the new Mac’s operating system.
Run Migration Assistant after the new Mac is already set up
You do not have to erase or reset a new Mac merely because you skipped migration during initial setup. Apple supports launching Migration Assistant later.
- On the new Mac, open Migration Assistant from the Utilities folder or with Spotlight.
- On current macOS releases, Apple’s Mac Help path is System Settings > General > Transfer or Reset > Open Migration Assistant.
- Choose From a Mac, Time Machine or startup disk.
- Open Migration Assistant on the old Mac and choose To another Mac.
- Select the source Mac on the new Mac, compare security codes if shown, choose categories, and begin.
Exact labels and locations can change between macOS releases. If your screen uses slightly different wording, choose the option that identifies the old Mac, a Time Machine backup, or a startup disk as the source.

Restore the new Mac from a Time Machine backup
Use this route when the old Mac is unavailable, when you already maintain a current backup, or when you prefer restoring from a known snapshot.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsConnect and identify the backup
- Connect the Time Machine backup disk to the new Mac.
- Open Migration Assistant during Setup Assistant or later from the Utilities folder, Spotlight, or System Settings > General > Transfer or Reset > Open Migration Assistant.
- Choose From a Mac, Time Machine or startup disk.
- Select the connected Time Machine disk and then choose the relevant backup when the available backups are listed.
Choose categories or individual items
- Wait while Migration Assistant calculates the storage available for restoration.
- Select the user accounts, applications, files and folders, and settings you want to restore. Depending on the backup and macOS version, you may be able to expand a category and choose individual items.
- Review the selection and start the restore.
Apple notes that a large Time Machine transfer can take hours and may look as though it has stopped. Keep the Mac connected to power and do not interrupt it solely because the progress display appears unchanged for a while.
Handle a same-name account carefully
If the new Mac already has an account with the same name as an account in the backup, Apple may offer two choices: replace the existing account or rename the old account so both remain. Read the prompt before selecting anything. Replacing can remove data currently stored in the new account; renaming preserves both accounts but may require you to move files or change which account you use as your main profile.
What happens to applications?
Applications can be included in a Migration Assistant transfer, but “included” does not mean every app will launch without work afterward.
Compatibility can prevent an app from transferring or running
Apple warns that an incompatible application, or an application for which a newer version is already installed on the new Mac, may not transfer or may not be usable. Compatibility can depend on the new Mac’s macOS release, processor architecture, required system extensions, and whether the developer still supports the software.

Plan for sign-ins and activation
The cited Apple instructions do not guarantee that paid-app activation, subscription status, cloud synchronization, saved passwords, or account sign-ins migrate. After the transfer, open each essential app and be prepared to sign in, enter a license key, approve a device, or install an update from the publisher.
Prioritize critical applications
Make a short list before migration: work tools, accounting or tax software, password managers, creative applications, development environments, device utilities, and any app that stores local data. Check the publisher’s compatibility and reactivation instructions for those items, then test them on the new Mac while the old Mac is still available.
Verify the new Mac before retiring the old one
Do not wipe, sell, or trade in the old Mac immediately after the progress bar completes. Use a deliberate verification pass.
- Sign in to every migrated user account you intend to keep.
- Open important documents from the new Mac and confirm that recent files, desktop items, and expected folders are present.
- Launch essential applications and complete any required updates, sign-ins, or license activation.
- Check cloud services and make sure synchronization is complete before judging that data is missing.
- Reconnect printers, external displays, storage devices, scanners, and other peripherals, then install compatible drivers or utilities if needed.
- Confirm browser profiles, mail accounts, calendars, contacts, and password-manager access.
- Review available storage on the new Mac and make sure the migrated account has enough space for future updates.
- Turn antivirus, firewall, and VPN software back on and test the network afterward.
- Run a fresh Time Machine backup from the new Mac if you want ongoing recovery protection.
Keep the old Mac untouched until these checks pass and you have another backup of anything you cannot replace.

Troubleshoot common migration problems
The Macs do not see each other
- Confirm both Macs are awake, connected to power, and have Wi-Fi enabled.
- Move them close together and close unrelated network-intensive applications.
- Temporarily disable antivirus software, third-party firewalls, and VPNs as Apple recommends.
- Quit Migration Assistant on both Macs, restart both computers, and repeat the source and destination choices.
- Check that you selected To another Mac on the old Mac and From a Mac, Time Machine or startup disk on the new Mac.
The security codes do not match
Do not continue. Cancel the connection, restart Migration Assistant on both Macs, and select the source again. Proceed only when the code shown on each computer is identical.

The transfer appears stuck
Large transfers—especially restores from Time Machine—can take hours and may appear to pause. Keep both Macs powered and connected. Interrupt only after you have allowed substantial time and ruled out a sleeping or disconnected computer. If you must restart, begin again from the latest usable backup rather than deleting data from the old Mac.
An account is missing or duplicated
Review the category selections and the account-conflict prompt. A same-name account may have been replaced or renamed. Sign out and check other user accounts on the new Mac before assuming files were lost.
An application is absent or will not open
Look for an existing newer version on the new Mac, then check the publisher’s compatibility guidance. Install a current version where available, re-enter the license or subscription credentials, and restore the app’s data from its supported backup or cloud service. Keep the old Mac available until the application works as expected.

Do you need a cable or an external drive?
External drive: useful but optional
A Time Machine disk is worthwhile when you want an independent backup, need to migrate without the old Mac, or want a recovery point before changing computers. It is not required for direct migration. If you buy one, confirm its capacity, connection type, and compatibility with your Mac before purchase; Apple’s support pages do not endorse a particular brand or model.
Thunderbolt cable: only for a specific model combination
Apple’s general Mac Help documentation describes a cable procedure for a narrow older-Mac scenario. That does not make a cable a universal requirement for MacBook migration. Check the exact model year, ports, operating systems, and cable capability before spending money. For ordinary current Mac-to-Mac transfers, start with the supported wireless Migration Assistant workflow.
When to erase or give away the old Mac
Erase the old computer only after you have verified files, applications, accounts, cloud data, and backups on the new Mac. Migration Assistant itself does not erase the old Mac, so you control when that final step happens. If an essential app, archive, or device still depends on the old system, keep it until you have a tested replacement path.
Quick Recap
Key decisions at a glance
- Both Macs work: choose direct Migration Assistant transfer.
- You have a current Time Machine disk: restore from that backup when it is more convenient or safer than using the old Mac.
- The new Mac is already configured: launch Migration Assistant later; a reset is not required.
- You are worried about licenses: prepare publisher credentials and test essential apps before retiring the old computer.
- You are considering accessories: treat an external backup drive as optional and a cable as model-specific, not mandatory.
