Artnet on Mac OS between 2 programs

[PrimalMic]

Hello,
I am using capture on my Mac Studio m2 and would like to also use Show Express in order to run some basic shows to test my design. I have tried an failed to get Artnet to talk between the 2 programs. I would ideally not want to use a separate hardware besides the 512s. Anyone know of a way to route Artnet between 2 programs on the same Mac machine?

Thank you tons!
