How to transfer files from Mac to Mac using a USB cable?

Perhaps, you think migrating files over the air is not secure enough for your secret files. Or, regarding that, the wireless data migration is time-wasting, especially for large files.

1. Use an external storage device

If you happen to have an available external storage device, like a USB flash drive or an external hard drive, you can use it as a bridge to transfer files between Mac computers.

You can connect the external drive to the Mac you want to transfer files from. Then, copy files or folders onto the drive and right-click the drive to safely Eject it.

Now, unplug the external drive from that Mac and reconnect it to the target Mac. Next, you can move the files on the drive to the Mac.

Target Disk Mode is to connect the two Macs with a USB or Thunderbolt cable to make an Intel-based Mac's internal hard drive perform as an external hard drive for the destination Mac machine. It is often used to transfer files from an old Mac to a new Mac because of the fast data transfer speed.

Here's how to use Target Disk Mode to transfer files from an old Mac to a new Mac:

  1. Use Thunderbolt or FireWire cable to connect the two computers.
  2. On the old Mac, click the Apple menu > System Preferences > Startup Disk > Target Disk Mode to restart the Mac into Target Disk Mode. The old Mac will show a Thunderbolt icon on the screen. 
    Boot into target Disk Mode on Mac
  3. On the destination Mac, open Finder. You can see the internal hard drive of the old Mac show up under the Locations tab on the left sidebar of Finder. Now, you can copy or move all or only the important files from the old Mac's drive to your new Mac.

3. Use Time Machine backups

This way is more suitable for some of you who want to migrate all the data on the old Mac to a new Mac computer, including the old Mac's preferences, applications, user accounts, and other files.

The detailed steps of transferring files to a new MacBook with Time Machine backup are as below:

  1. Back up your old Mac (If you have, skip this step).

  4. Select Restore From Time Machine Backup in macOS Recovery Mode and click Continue. 
    Restore from Time Machine in macOS Recovery mode
