Migrating Mail and Browser Profiles to a New Mac

Transfer your Apple Mail data and browser profiles to a new Mac using Migration Assistant and manual folder syncing for complete data integrity.

  1. Close all active applications. Quit Mail, Safari, Chrome, and Firefox on your current Mac to prevent file locking. Open the Activity Monitor via Command + Space, search for these processes, and force quit if they remain active to ensure no data corruption occurs during the migration process.
  2. Run Migration Assistant. On both Macs, open Migration Assistant from Applications > Utilities. Follow the prompts to connect the devices via Thunderbolt cable or Wi-Fi. Select your user account and ensure the checkboxes for Library and Application Data are toggled on to migrate your Mail and browser settings.
  3. Verify the Mail data path. If data did not carry over automatically, navigate to ~/Library/Mail/V10 on your old Mac. Copy the folder to an external drive. On your new Mac, open Mail, go to File > Import Mailboxes, and select the Apple Mail format to map your existing local folders.
  4. Restore Chrome profiles manually. Navigate to ~/Library/Application Support/Google/Chrome on your source Mac. Copy the 'Default' or 'Profile X' folders to the corresponding directory on your new Mac. Launch Chrome to re-authenticate your Google account and finalize the profile synchronization.
  5. Authorize your new machine. Open the Apple Music or TV app, navigate to Account > Authorizations, and select Authorize This Computer. This ensures that any DRM-protected content associated with your browser or account sync services functions correctly on the new hardware.
