How do I use the Thunderbolt 3 to Thunderbolt 2 adapter to connect a hard drive with Thunderbolt 3 to a Mac with Thunderbolt 2?

I will need to make one assumption and that is that the USB-C (Thunderbolt 3) connection on the Hard Drive is a female connection. Here is what I come up with-

You will need the ➔ Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter. See Image below-

The USB-C end will connect to your Hard Drive.

You will also need a ➔ Thunderbolt 2 Cable if you do not already have one.See image below-

One end of the Thunderbolt cable will go in the adapter and the other to your Mac.

great answer, Axel F.!

Remember that adapter does not supply POWER , so the drive needs external power supply.

Great Point Grant. Need to confirm with OP that the Drive has external power supply.

Hello mlundber,

Can you confirm whether the external hard drive comes with its own power supply?
