How to Transfer Files and Apps to a New MacBook

This guide walks you through moving your files, settings, and applications from an old Mac to a new MacBook. It covers three main methods — Migration Assistant, Time Machine, and manual transfer — so you can choose what fits your situation. You’ll learn what to prepare beforehand, the exact steps for each method, and how to avoid common pitfalls.

What You’ll Need

  • Both Macs plugged into power (especially the new one).
  • Both Macs connected to the same Wi-Fi network, or a USB-C to USB-C cable for a faster wired transfer.
  • Your Apple ID and password.
  • Enough free storage on the new Mac (check in About This Mac → Storage).
  • If using Time Machine: an external drive with a recent backup.
  • If using manual transfer: an external drive or cloud storage with enough space.

Step-by-Step

Method 1: Using Migration Assistant (Recommended)

  1. Update both Macs to the latest macOS version compatible with each machine (System Settings → General → Software Update).
  2. On your new Mac, open Migration Assistant (in Applications/Utilities). If you’re setting up the new Mac for the first time, you can also choose Migration Assistant during the initial setup.
  3. Choose the transfer method: select From a Mac, Time Machine backup, or startup disk, then click Continue.
  4. On your old Mac, open Migration Assistant too (in Applications/Utilities). Click Continue, then select To another Mac.
  5. Connect the two Macs: If you have a USB-C cable, plug it into both. Otherwise, ensure both are on the same Wi-Fi network. Migration Assistant will detect the other Mac.
  6. Verify the code: A 6-digit code will appear on both screens. Confirm they match, then click Continue on both.
  7. Select what to transfer: You can choose to transfer all files, or only specific categories (Applications, Documents, System Settings, etc.). Uncheck anything you don’t need.
  8. Start the transfer: Click Continue and wait. The time depends on the amount of data and the connection speed (USB-C is fastest). Your new Mac may restart during the process.
  9. Finish setup: When done, sign in with your Apple ID and check that your apps and files are present.

Method 2: Using Time Machine Backup

  1. On your old Mac, make sure you have a recent Time Machine backup. If not, go to System Settings → General → Time Machine and back up to your external drive.
  2. Connect the backup drive to your new Mac.
  3. Start Migration Assistant on the new Mac (or choose it during initial setup).
  4. Select “From a Mac, Time Machine backup, or startup disk� and click Continue.
  5. Choose the backup drive from the list, then select the most recent backup snapshot.
  6. Select what to transfer (similar to Method 1) and click Continue.
  7. Wait for the transfer to complete. The new Mac will restart when done.

Method 3: Manual Transfer (Files Only)

  1. Connect an external drive to your old Mac, or ensure you have cloud storage (iCloud Drive, Dropbox, etc.) with enough space.
  2. Copy your files: Drag and drop Documents, Desktop, Pictures, Music, and any other important folders to the external drive or cloud.
  3. Eject the drive safely, then connect it to the new Mac (or sign in to cloud storage on the new Mac).
  4. Copy the files from the drive/cloud to the new Mac’s appropriate folders.
  5. Reinstall apps: You’ll need to download your apps again from the App Store or the developer’s website. Some apps (like those with licenses) require you to deactivate them on the old Mac first.
  6. Transfer settings manually: For things like email accounts, Wi-Fi passwords, and browser bookmarks, you may need to set them up again or use iCloud sync.

Common Mistakes

  • Not updating macOS first – If the new Mac runs a much newer version, Migration Assistant may fail or miss some data.
  • Using Wi-Fi when a cable is available – A USB-C cable is much faster and more reliable, especially for large transfers.
  • Not checking storage space – If the new Mac has less free space than the data you’re transferring, the process will fail.
  • Interrupting the transfer – Let it run to completion; putting the Mac to sleep or unplugging the cable can corrupt data.
  • Assuming apps will work without reinstallation – Some apps (especially older ones) may not be compatible with the new macOS version.
  • Forgetting to deactivate licenses – For paid apps, you may need to sign out or deactivate on the old Mac to use them on the new one.

Tips

  • Clean up before transferring – Delete old files and apps you no longer need to speed up the process and save space.
  • Use a wired connection if possible – A USB-C to USB-C cable (or Thunderbolt) is significantly faster than Wi-Fi.
  • Keep both Macs plugged in – A power loss during transfer can cause issues.
  • Check app compatibility – Before transferring, look up whether your essential apps support the new macOS version.
  • Use iCloud for continuous sync – After the transfer, enable iCloud Drive, Photos, and Desktop & Documents to keep files in sync automatically.
  • Back up your old Mac – Even if you’re using Migration Assistant, it’s wise to have a separate Time Machine backup as a safety net.

Troubleshooting

  • Migration Assistant can’t find the other Mac – Make sure both are on the same Wi-Fi network and have Bluetooth enabled. Try restarting both Macs, then reopening Migration Assistant.
  • Transfer is stuck or very slow – If using Wi-Fi, try moving closer to the router or switch to a wired cable. Also, close other apps that might be using the network.
  • Error message about insufficient storage – Free up space on the new Mac by deleting unnecessary files or using an external drive for temporary storage.
  • Apps don’t work after transfer – Some apps may need to be reinstalled or updated. Check the App Store for updates, or download the latest version from the developer’s website.
  • Transfer keeps failing – Try using a different method (e.g., Time Machine instead of Migration Assistant). Also, ensure both Macs have the latest macOS updates.
  • Files are missing after transfer – Check the Users/Shared folder and the Users/[yourname] folder. Sometimes files are placed in different locations. Use Spotlight to search for specific filenames.

Frequently Asked Questions

Can I transfer apps without reinstalling them?

Yes, Migration Assistant can copy apps, but they may need to be updated or reactivated. Some apps with DRM or licenses might require you to sign in again.

How long does the transfer take?

It depends on the amount of data and the method. A USB-C cable can transfer 100 GB in about 30–60 minutes; Wi-Fi can take several hours for large amounts.

Will my passwords and Wi-Fi settings transfer?

Yes, if you use Migration Assistant or Time Machine, system settings and saved passwords (from Keychain) are transferred. Manual transfer does not include these.

Can I use my old Mac after the transfer?

Yes, but it’s recommended to erase it after you’ve confirmed everything works, especially if you plan to sell or give it away.

What if my old Mac is too old to run the latest macOS?

Migration Assistant still works as long as both Macs can run a compatible macOS version. You may need to update the old Mac to the latest version it supports.

Do I need to deactivate apps on the old Mac?

For apps that have a limited number of activations (e.g., Adobe, Microsoft), yes. Check the app’s licensing terms and deactivate on the old Mac before transferring.
