Thunderbolt 4 host computers
Thunderbolt 4 is essentially Thunderbolt 3 but with a few additional requirements.
Unfortunately, we've found that the Thunderbolt 4 implementation on a number of systems is problematic when Thunderbolt 1 or 2 devices (like the Clarett Thunderbolt range) are connected, often leading to crashes ("blue screens"). These crashes are nothing to do with Focusrite's devices or drivers and instead relate to a low level interaction problem with the host Thunderbolt controller.

Thunderbolt 3 host computers
While, in theory, all Thunderbolt 3 systems should work the same from our testing we have found that this is not always the case. We’ve therefore qualified some Thunderbolt 3 systems as working correctly – you can find more information about which systems we’ve tested and can therefore recommend, as well as a link to the correct page on our beta site so that you can install the latest driver in this article.
Although we would like to, it is impossible for us to test every Thunderbolt-equipped PC in the field. We can only guarantee performance on machines that we have tested - your mileage may vary with non-qualified systems and our support team may not be able to assist you if you’re attempting to use a system we’ve not tested as working (though we'll do our best!).
Thunderbolt 1 and 2 host computers
As of 2020 Focusrite no longer tests computers with Thunderbolt 1 or 2 ports. If you already have a PC with a Thunderbolt 1 or 2 port fitted as standard it may work without issue with a Clarett Thunderbolt interface, however this cannot be guaranteed.
Adding a Thunderbolt port to your computer
If your computer doesn’t have a Thunderbolt port and you plan on purchasing a PCIe card to obtain Thunderbolt connectivity, you will need to find a card which is compatible with your motherboard. Not all motherboards have the capability for Thunderbolt expansion, you'll need a spare PCIe slot and a Thunderbolt 'header'. Please consult your motherboard vendor or PC manufacturer for details on which card to buy and how to install and configure appropriately as Focusrite may not be able to support you with this.
