How to Use Migration Assistant: Move Data to Your New Mac (2026)
If you want to transfer files, apps, and settings to a new Mac, Apple Migration Assistant is the easiest and most reliable tool available. It allows you to move your entire user account, documents, applications, and system settings from an older Mac, Windows PC, or Time Machine backup.
This built-in macOS utility simplifies the process when upgrading to a new MacBook Air, MacBook Pro, iMac, or Mac Studio. If you are setting up a new device and want to avoid copying files manually, Migration Assistant can handle the entire transfer in a single guided process. For example, after moving your files you may also want to review how to take a screenshot on Mac since many users customize shortcuts again after migrating systems.
This guide explains how Migration Assistant works, when to use it, and how to transfer your data safely.
What Is Apple Migration Assistant and How Does It Work?
Migration Assistant is a built-in macOS tool designed to transfer data between computers or from backups. It copies essential data such as user accounts, applications, documents, and system preferences to a new Mac.
The tool supports several migration sources:

- A Time Machine backup
- A startup disk or external drive
It works on both Intel-based Macs and Apple Silicon devices powered by chips such as M1, M2, M3, and M4. The transfer can occur over Wi-Fi, Ethernet, or through a direct cable connection for faster speeds.
