Thunderbolt 3
Use Thunderbolt 3 with displays and other devices that connect using either a Thunderbolt 3 cable or USB-C cable. You can also connect a USB-C power adaptor and cable to charge your notebook computer. If you have a device that doesn't connect to this port, you might be able to use an adaptor to connect it.
These Mac models have Thunderbolt 3 ports:
- MacBook Pro introduced in 2016 or later
- MacBook Air introduced in 2018or later
- iMac introduced in 2017 or later
- iMac Pro (all models)
- Mac mini introduced in 2018
- Mac Pro introduced in 2019
If your Mac notebook or desktop computer has more than one port like this, each port supports ThunderBolt 3 and USB-C.
USB-C
Use USB-C with displays and other devices that connect using a USB-C cable. You can also connect a USB-C power adaptor and cable to charge your notebook computer. If you have a device that doesn't connect to this port, you might be able to use an adaptor to connect it.
MacBook models introduced in 2015 or later have a single USB-C port. This port doesn't support Thunderbolt devices.
If your Mac has only one port like this, it's a MacBook that supports USB-C but not Thunderbolt.
Thunderbolt
Use Thunderbolt or Thunderbolt 2 with displays and other devices that connect using a Thunderbolt cable.
These Mac models have Thunderbolt or Thunderbolt 2 ports:

- MacBook Air introduced in 2011 until 2017
- Mac mini introduced in 2011 until 2014
- iMac introduced in 2011 until 2015
- Mac Pro introduced in 2013
