Connect two Macs using Thunderbolt

  • Power off the Mac you would like to use in Target Disk Mode and connect a Thunderbolt cable from it to another Mac you intend to access it from.
  • Power on the Mac whilst holding down the T key.
  • After a few seconds, the Thunderbolt logo will appear on the Mac signifying it’s now in Target Disk Mode.

Now that the Mac is in Target Disk Mode, it will appear as an external hard drive on the Mac it’s connected to. You can then access any data that may reside on the Mac and even use Migration Assistant, providing an automated way to transfer your documents and applications from an old Mac to a new one.
