Migration Assistant needs something to transfer from ; that something can be a Mac, a PC running Windows 7 or later, or a Time Machine backup drive. The source computer can be connected to the same network via wired Ethernet or Wi-Fi as the new Mac, or via a direct Ethernet connection between the old and new computers. A Time Machine backup drive must be directly connected to your new Mac or over the network if an Apple AirPort Time Capsule device is used for the backup.
If you want to transfer files from a Windows PC to a new Mac, you also need to install and run the Migration Assistant for Windows software on the PC; the required version of that software depends on which version of macOS you have.
You can also initiate a Migration Assistant transfer to another Mac, which requires Migration Assistant to be running on that Mac. Click image to enlarge it.

MacOS has also long had the built-in Time Machine backup utility that lets you restore an entire Mac — applications, files, settings, and so on. It resides in the Applications folder.

Tip: You can also restore specific files from a Time Machine backup drive onto a new Mac. Use the Migration Assistant utility, covered in the previous section, to do so.
Time Machine is the gold standard for computer backup. To set up backup, connect an external drive to your original Mac. Connecting the backup drive via USB or other wired port is the fastest method, but you can also use a wired or wireless network if your backup drive is connected to a Time-Machine-compatible router, as many recent routers are. Restoring or cloning a Mac from Time Machine is a bit more complicated. First, shut down your new Mac, then connect your Time Machine backup drive to it.
Be a little patient until the macOS Utilities window opens. You may get a list of available backups, since Time Machine maintains a history that lets you choose an earlier backup if desired, such as to restore a Mac from before it became infected with a virus or got corrupted. In the next window you will be asked what drive to restore the backup to.
In this case you want the startup drive for your new Mac; select it and then click Restore. Click C ontinue to start the transfer. After Migration Assistant is done, log into the migrated account on the new Mac to see its files.
