What Do You Need For Your Mac To Transfer Files Via Target Disk Mode?

Since this is not an in-computer process and requires a secondary mac, there are a few things you need to take care of.

• 2 Mac computers: To transfer files from one Mac to the other, having two fully functional Mac is the first step. Ensure that both of them have either a Thunderbolt port or a Firewire port.
• A Firewall or Thunderbolt Adapter Cable: A regular USB port will not be enough for this kind of file transfer as these macs have Thunderbolt or Firewall ports. So make sure that you have an adapter cable that can connect to these ports. And if one of your macs has a Thunderbolt port and the other has a Firewall one, you will need a Thunderbolt-to-Firewire Cable and vice versa. Moreover, if both have a thunderbolt or Firewall, then you need that sort of wire.
• Disable File Vault: By default, all Macs now have file vault encryption to prevent anyone from accessing home directories over Target Disk Mode. So, you have to disable this option. And to do that, start the Mac usually, go to System Preferences, choose Security and Privacy. Furthermore, select file vault and switch it off temporarily. Enable it again after using the Target Disk Mode.
• Remove Firmware Password: Disable the firmware password for a while till you are using Target Disk Mode.
