All Apogee Thunderbolt interfaces can be connected to Mac computers with USB-C Thunderbolt 3 using Apple’s adapter:

Thunderbolt 3 is backwards compatible with Thunderbolt 2 and Thunderbolt 1 devices so any Apogee Thunderbolt device will work through this adapter with no reduction in performance, latency, or sound quality.

Note: Some 3rd-party venders sell a Display Port adapter. Though the plug is the same size and shape as Thunderbolt 2 & 1, these adapters do not support Thunderbolt.

It should be noted that Thunderbolt 3 ports look exactly like USB-C ports and their cables also look similar. This can get a little confusing, so here are a few basic rules to help clear up any questions about connectivity:

  • USB-C and Thunderbolt 3 have the same-size port and the same-size connector for their cables. Since USB-C and Thunderbolt 3 ports look exactly the same, you will need to make sure your Mac has Thunderbolt 3 capabilities before using it with an Apogee Thunderbolt device and an Apple Thunderbolt 3 to Thunderbolt 2 adapter.
  • A Mac with Thunderbolt 3 ports, such as the 2016 MacBook Pro with Touch Bar, can use it’s Thunderbolt 3 ports to connect to any Thunderbolt 3 device, USB-C device, and Thunderbolt 2 or Thunderbolt 1 device if you use the Apple Thunderbolt 3 to Thunderbolt 2 adapter.
  • A Mac with only USB-C ports, such as the 2015 and 2016 12″ MacBook, can NOT connect to any Thunderbolt device, even when using adapters. It can connect to USB-C devices and other types of USB devices, using the proper adapters.
