To capture general audio on Mac you might try BlackHole or Soundflower:


Would that do the trick?

It is possible to run Jack on macOS but only for jack-supported applications like certain professional music software and open source tools.

Apple has carefully crafted their OS to prevent you from doing that, for digital rights management reasons, so the OS doesn't give jack access to any audio beyond the boundaries of jack itself. It's like the post office: You can send a letter to me, and someone else can send a letter to me too. I get to see both, but you will never know anything about the other mail I get, unless I share it with you. Apple doesn't share.
