Need to Move Lots of Data Between Macs Try Target Disk Mode
We can move data between Macs. You can send files via AirDrop, attach them to an email message, put them in a Messages conversation, turn on and connect via File Sharing, or use Dropbox or Google Drive as an intermediary, to name just a few of the more obvious approaches. Additionally, you can also use other cloud storage services like Microsoft OneDrive or pCloud, or even transfer files directly using a USB drive or external hard drive.
