How to Transfer Data to a New MacBook

Just got a new (or used) MacBook and need to move your files, apps, and settings? There are three ways to do it. This guide covers all three, tells you which one to use based on your situation, and walks you through each step-by-step.

Which Method Is Right for You?

Migration Assistant (Mac to Mac) BEST FOR MOST

If you have your old Mac and it still works, Migration Assistant transfers everything — apps, files, settings, passwords, even your dock layout — directly over WiFi or a cable. It's the easiest and most complete method.

Use when: you have both Macs available and your old one works
Transfers: everything (apps, documents, settings, passwords, email, photos)
Time: 30 min to 2+ hours depending on how much data you have

Time Machine Backup GREAT IF YOU BACK UP

If you have a Time Machine backup on an external hard drive, you can restore from it during Mac setup. This gives you the same complete transfer as Migration Assistant, even if your old Mac is broken, sold, or unavailable.

Use when: you don't have the old Mac but have a Time Machine backup
Transfers: everything that was in your last backup
Time: similar to Migration Assistant — 30 min to 2+ hours

iCloud + Manual Transfer USE WHEN NEEDED

If you don't have the old Mac or a backup, you can sign into iCloud on the new Mac to restore documents, photos, contacts, and calendar — then manually reinstall apps. Not as seamless, but it works.

Use when: no old Mac, no Time Machine backup
Transfers: iCloud content (documents, photos, contacts, notes, mail)
Apps: must be reinstalled manually from the App Store or each developer's website
Time: a few hours, spread across a day as apps reinstall

Method 1: Migration Assistant (Mac to Mac)

Before you start

Update both Macs to the latest macOS they support. This prevents compatibility issues during transfer.

Connect both Macs to power. A transfer that dies halfway through is worse than not starting one.

Connect both to the same WiFi network — or use a USB-C cable for a faster transfer.

On the new Mac (during first-time setup)

When you first power on a new or freshly erased Mac, the setup assistant will ask "How do you want to transfer your information?" Select "From a Mac, Time Machine backup, or Startup Disk."

If you've already completed setup, open Applications → Utilities → Migration Assistant and run it from there.

On the old Mac

Open Migration Assistant (Applications → Utilities → Migration Assistant).

Select "To another Mac" and click Continue. Enter your admin password if prompted.

A code will appear on both Macs. Confirm they match, then select what you want to transfer — Applications, User Accounts (your files and settings), and Other Files and Folders.

Click Continue and let it run. Don't put either Mac to sleep. When it finishes, the new Mac restarts with everything transferred.

Tip: If you're transferring over WiFi and have a lot of data (100GB+), expect 2–4 hours. A USB-C cable between both Macs cuts this to 30–60 minutes on most setups.

Method 2: Restore from Time Machine

Steps

Connect your Time Machine drive to the new Mac using a USB-C adapter if needed.

During first-time Mac setup, select "From a Mac, Time Machine backup, or Startup Disk" when asked how to transfer.

Select your Time Machine backup from the list. Choose the most recent backup.

Select what to transfer and click Continue. The Mac will restore from backup and restart.

If you've already completed first-time setup without restoring, open Migration Assistant (Applications → Utilities) and select "From a Time Machine backup" to run the restore at any time.

Method 3: iCloud + Manual App Reinstall

Steps

Sign into your Apple ID during Mac setup. iCloud will begin syncing your Documents, Desktop, Photos, Contacts, Calendar, Notes, and Reminders automatically.

Open the App Store and go to your account → Purchased. Reinstall every app you downloaded from the App Store.

For apps not from the App Store (Adobe, Slack, Zoom, Spotify, etc.), download and reinstall each one from the developer's website. You'll need to sign back into each.

Re-enter passwords in Safari → Passwords (or use a password manager to restore your vault). Keychain passwords from iCloud sync automatically if you enabled iCloud Keychain.

Restore any files stored locally (not in iCloud) by copying them manually from an external drive or AirDrop from the old Mac if it's still accessible.

Transferring from a Windows PC to a Mac

If you're switching from Windows, Apple has a free app called Move to Mac (available from the Microsoft Store) that works alongside Migration Assistant on your new Mac. It migrates contacts, calendars, photos, music, documents, and some settings. Apps don't transfer — you'll need Mac versions of any software you use.

On the new Mac, open Migration Assistant and select "From a Windows PC"
Install the Move to Mac app on your Windows PC
Follow the on-screen prompts on both machines — they'll connect over your local network
Select what to transfer and let it run

After the Transfer: Quick Checklist

Check that your files transferred — open Documents and Desktop, confirm everything is there
Sign into apps that need re-authorization — Adobe, Microsoft Office, Slack often prompt you to sign in again
Check your email is set up and syncing in Mail
Test your most-used apps to confirm they open and work correctly
Wipe the old Mac after confirming everything transferred — System Settings → General → Transfer or Reset → Erase All Content and Settings
