Audio output with headphones on Mac

Hello ! I just started to use VCV rack and I am struggling trying to use my headset. When I choose external in Audio, I can use the mic as an input (I can play it on the computer speakers) but I can’t set it as an output. Well I can but I have no sound. Have you already come across this problem ? I am running VCV on mac. Thanks for your help !

Either make an aggregate device or use two audio modules, which you can do now in Rack v2.

not aggregate, multi-output device, I have had zero luck when by accident I created an aggregate device, works fine if I use Multi-output device in Rack, and Blackhole as the receiver in QT. Seriously low CPU overhead and very low latency solution
