Using MacBook as external audio interface

You cannot use the old MBP as a "through" interface between the TC Electronics device & another Mac.

And unfortunately, Apple discontinued "Firewire CoreAudio Support" in macOS Ventura; so even if you got the necessary adapters to connect a Firewire device to a new Apple Silicon Mac, it still wouldn't work.

It's time to move on to a USB-based audio interface.

Without the vendor's own driver, connecting via Firewire would require CoreAudio. The device is old enough that the driver is probably 32-bit, which means it will not run on Catalina or any more recent version of macOS.

I did a little research and your TC Twin also has SPDIF & Optical digital outputs. You *MAY* be able to use it with a thunderbolt hub like this one connected to a modern Mac. However it is still unlikely you would be able to use the Control Panel app, as that is also probably 32-bit and it requires the Firewire interface. But you could use other recording apps with the Twin as a basic analog/digital converter.

There are a lot of 'ifs' there ... it would require some experimentation. If your old 2011 MBP has SPDIF input (I think they did back then) you could attempt to connect that way and see if it works. Keep in mind, however, that the ControlApp probably doesn't work without a Firewire connection.

There's no way to use your 2011 MacBook Pro as a Firewire adapter, if that's what you're asking about.

Apple never came out with a Thunderbolt 3 to Firewire adapter. They had a Thunderbolt 1 to Firewire 800 adapter that you could daisy-chain with a Thunderbolt 3-to-2 adapter … but they discontinued that Firewire adapter a few months ago (?), and now it seems to be out of stock everywhere.

I've also read (on these forums) that in some recent version of macOS, Apple removed Core Audio support for plug and play Firewire audio devices that don't have their own device drivers. That's another issue you might encounter even if you can somehow find the hardware needed to make a Firewire connection.

The elephant in the room is that even with adapters, it will likely not work on the new Mac.

It is possible that this may not work either as it could still have 32 bit components and macOS has been 64 bit only for several years now. Also, even if all the components of the driver are 64 bit, it may still not work on current macOS because of several changes to how drivers are handled since High Sierra. Also, on top of that, the new "M" series CPUs are a totally different architecture from Intel Macs and requires drivers built for that processor architecture. So unless the vendor of your device has written drivers for the new Macs, you are out of luck.

So, even if you found a functional adapter scheme, you still will likely be out of luck getting it to work.

Beware of so-called USB-to-Firewire adapters.

You cannot convert USB to Firewire simply by gluing a USB connector to a Firewire connector and wiring together some pins. USB and Firewire are too different. If you are lucky, things just "won't work" – if you aren't, those pins will be wired together in a way that may cause damage to your equipment.

Thunderbolt (any version) to Firewire – theoretically yes, even if there are no TB3-to-FW or TB4-to-FW adapters actually available on the market.

USB to Firewire - world of hurt.

I suppose you want to continue using the ControlApp to manage the TC Twin. You could just continue using it with your 2011 MBP & TC Twin. Then use File Sharing to transfer your digitized audio files to another (new) Mac.
