How do I transfer everything from my old iMac to my new iMac?

Before upgrading to a new Mac, it's essential to move your apps, files, user profiles, and preferences from the old machine. Apple simplifies this process with a built-in utility known as Migration Assistant.

This tool typically connects both Macs over Wi-Fi, but for faster and more stable transfers, you can also use an Ethernet or USB-C cable. Once connected, you'll be able to select exactly what data—folders, files, and settings—you want to carry over, ensuring your new Mac is ready to go with everything you need.
